  1. Trevor, I fully understand how to get from a U-Value to an R-Value, that is not the issue. The problem is that in Energos the R-values for equivalent constructions is of the magnitude of 0.17 (check the pre-populated values for some of the generic wall constructions), which would using the formula U = 1/R, give a U-value of 5.88 which is the same as a polythene sheet!! This is obviously wrong. I have done some more digging and found that in the US the R value unit is h.ft.ºF/Btu. How are we meant to use a system that cannot calculate values in metric. Also means that there must be a 'fiddle' in the software to export to PHPP - as that system is fully metric.
  2. Can someone please help me with the data input requirements for Energos. More specifically what the R-Value is and how do I relate it to the U-Value of a construction. Example: I have a project where the wall makeup is 140mm timber kit using 120mm 0.022 rigid board (thermal conductivity in W/mK) reflective membranes and a standard Low-E service zone internally finished internally with 2 layers 12.mm plasterboard and externally there is an existing sandstone wall with a 70mm cavity. This gives a U-Value of 0.19 W/m2K (Watts per square metre per degree Kelvin), the equivalent R-Value for that construction is 5.304 m2K/W. This makes no sense whatsoever in the Energos calculations, as R-Values for the equivalent constructions in the database are similar to the U-value (but not the same). Is there a units or conversion problem? - Ie. The building is being constructed in metric (SI units) and does Energos work in imperial?? If so there is a serious problem wth the software engine. Or have I just got it completely skewed. I have attached the wall U-Value calculation for information Please help.
  3. Kizza, That's the only way I could think of doing it as well. The situation is that my client's engineer uses PDS software to create the roads and drainage model and I am have to generate the site profiles for planning (comparing existing and proposed etc.) and for sales so that they can see the garden slopes. I can generate two independent site models, have them on two independent layers and then view generate the sections etc. Only thing is that I have to generate everything twice. The problem was in this case the engineer had only modelled the altered area so the existing survey model and the proposed model didn't marry up (as far as the extents were concerned. I had to trace round the proposed contour model, trim it from the existing survey model and then combine the two into a single drawing which would then match the extents of the survey. Thanks anyway. Kevin.
  4. I have an engineer who has carried out the engineering on a housing layout for a small site. I now have two 3D autoCAD files. 1. The existing site survey and 2. The proposed site levels and contours I know how to generate two individual site models and work on them individually. The question is can I import the survey model as the existing terrain model and import the proposed site level drawing as the proposed site mode, merge them together, then add the houses etc. to the proposed. Kevin.

  6. Carrie, Joining two separate files using the same technology as AutoCAD doesn't wok in VW. I.ei inserting a file as block then exploding it. The only way to combine files that I am aware of is to join the two files together by importing the layers and objects. Let me explain: 1. Create a new file (with blank template). 2. In the navigation palette, create a new layer, but instead of selecting "Create a new layer name" choose "Import Design Layers". 3. Using the "Choose" button navigate to the file you want to import from an select it. 4. The layers in the VW file will now appear in the dialogue box - Select the layer, but remember to also ensure that the "Import layer objects" check box is ticked. Repeat for the layers you want to import in all the files you want to import from. If there are layers of the same name - VW will add a suffix the the new year -1, -2 and so on. Doing it this way will bring in layer heights etc. Hope this helps. Kevin.
  7. Fergus, Is this what you are looking for - Standard rebated windows and doors. The attached file is a screenshot of a 10mm facing brick blink over the kit - Client required all opening to be brickwork sizes. Unfortunately VW cannot show firestops or lintels for timber frame (which is a shame). The Cill detailing is getting better, but still a long way to go. It is actually quite straightforward - once you get round the quirks of VW. 1. Create your window and put it in the wall (Take a note of your jamb and wall width). This is typical apartment external wall (U-Value 0.19) Example: 372mm wall (2 x 12.5mm plasterboard / service void 140mm kit / 9.5mm OSB / 50mm cavity / 102.5mm Facing Brick) Window jamb = 65mm thick Will require an offset of 51mm to sit the window frame on the inner brick face (Standard detailing) 2. Adjust the window offset - It always has to be moved. Who wants to put a window in the middle of the cavity???? 2. In window settings - go to components and select 1 external component (no splay. This will now put a drag grip on the LH side of the window. To adjust the blink size, just select and drag. I usually select / drag then hit tab and enter the distance (10 / 15 / 20mm) as required. If you have a roughcast finish to the external leaf, select 2 external components (and so on). 3. The Internal is just the same as the external although you can also drag the internal finish horizontally and vertically (either by feel or by specified distance). Hope this helps. Kevin.
  8. I've always had the same problem. I have just ended up creating a custom field in the worksheets. Anyone who has not come across this problem is obviously not exporting their models for take-off and scheduling. What is needed is the ability to create a custom gap at the head and base for "fitting" and a custom threshold / weather strip (if needed), or even better - allow for a carpet tolerance. We should be allowing at 15mm gap at the door base. Or even better having a tab in the door settings which allows there to be different shim gap for the jamb, cill and head. I presume that you are using a standard metric door. Internally (let's say a 826x2040 door). If the door frame is 35mm thick you would normally have a 2mm gap between door and frame and a 5mm fitting tolerance giving a structural opening width of 910mm. For the lintel height above FFL you would again have a 2mm gap at the head, 15mm gap at the floor - this gives a module height of 2092 leaving 18mm shim gap at the head between the frame and lintel. If you have to use one of those stupid imperial doors - you just end up with a bigger gap at the head. The problem only arises though when you are building with masonry internal walls - if you're using timber kit, you can just adjust the lintel height to suit (2064mm AFL, rings a bell for lintel height). Externally - you have to tie in with standard coursing and you end up with shim gaps which have to be filled either with timber packers or something else. The only way round this is by old fashioned large scale jamb / head and cill detailing
  9. I would always import a dwg file into a blank VW file and then reference the new VW file into the project and a design layer viewport. Reasons for: 1. You can export the dwg reference file as a dwg file back to the originator easily 2. If you import a dwg file directly into VW it will overwrite your class settings (dwg file imports always have fill on as solid - causes havoc with drawings) 3. You can always overwrite the dwg settings in the advanced settings tab of a design layer viewport to display how you want it to 4.Your file will not get overloaded with autoCAD layers (classes) - they will only show up in the viewport, which you can then customise. Reasons against - None that I am aware of. One thing that would be good for VW importing and exporting dwg files is the ability to use the dwg originators ctb file from an e-transmittal (or one which we have created ourselves), then we would be able to replicate the file settings and stop the constant moaning from autoCAD users about linetypes and colours to being incorrect
  10. Amelia, Once you have joined the walls, you have to join the components. VW isn't very smart in this respect and you have to tell it which components should be joined in on place and which components nee dot be joined in a corner. It will take a bit of practice, but when it works its great. Regards, Kevin.
  11. Amelia, They are two separate roofs, so imho there will always be a junction between them - hence the line. I would think that the only way to hide the line is to draw a 3D polyline around the whole coplanar roof surface in the plane of the roof and either attach a roof finish to it (roof tiles?) or a simple shade. Also if you have Renderworks, you can attach a render to the face of the roof and Renderworks should merge the two together (I think). Regards, Kevin.
  12. Tim, Yes that's the whole process time. Kevin.
  13. I have recently started using the callouts and the database manager to generate standard office text and specification. The ability to have a central notes database which can be updated and used to update other drawings is brilliant, but I have found some (what I feel are) major shortcomings. 1. When trying to import notes from the database say for a Building Warrant submission, there are standard notes which must be included every time. Why is the only way that I can import the notes is in a form that is predetermined and completely inflexible Eg. A) The only way to import notes from the database is to import through callouts - Why??? A callout by default require a leader, and is usually a short text string. I want to have access to an office database which contains specification and notes and that can be used to generate a full project specification if required. B) Callouts are near impossible to format, other than the most basic of editing What would be great is if when selecting the callout from the basic tools and the dialogue box opens (either stand alone or importing from the database) - Could we have an Insert as callout or Insert as notes button and allow custom formatting to the notes (see below) 2. Often projects will have notes from different parts of the databases. Why can these not be inked so that when one note ends the next one begins directly afterwards (and copies the same formatting (Ie. width of text box / font and size etc.). Linking different 'callouts' would also allow for easier editing and mean that when the office database is updated, if a project requires to have its notes amended, the whole specification wouldn't have to be reformatted, which at the construction stage, could mean dozens or even hundreds of drawings 3. Start using columns so that notes can flow instead of having to create multiple viewports which have to be adjusted every time a note gets updated 4. Allow for importing from word processing programs (copy and paste - with formatting) or direct import from Word (Exporting to word would be nice to have as well)
  14. +1 for me. Could be used to standardise all drawings and make for a corporate style which would then be consistent. The option is there with the eyedropper tool to make various viewport properties match each other, but to have this as an office wide resource would be great.
  15. Is there any way that VW can be set to either produce a warning when exporting to pdf if the file size is going to be greater than a predefined level. For example (I think i've mentioned before in other posts) - Preparing submission packs for Planning Consent - no file can be greater than 5MB. Also when creating viewports in sheet layers, it would be great if the object info pallet could give an estimate of the proposed pdf file size of that sheet so that adjustments could be made to viewports (resolution up or down) before sometimes waiting an hour or two (or more) for the pdf file to be generated only to find that the file size is too large and you have to start all over again.
  16. Jim, Following up from Tim's post (and your reply), BREEAM is not the UK Government approved tool for demonstrating compliance with the Building Regulations - The UK tool for domestic buildings is SAP and for non-domestic it is SBEM, neither of which are mentioned anywhere. BREEAM, although a very good tool will not tell you whether your design complies with the relevant regulations (neither does Passivhaus - for the UK anyway). Can you expand what you mean by the compliance presets? If ENERGOS is meant to give an idea how energy efficient a building is, it has to be against a benchmark that is recognised. For the UK that is SAP for domestic and SBEM for non-domestic. Interesting what you are saying about the xml files - Will the energy model be able to export the xml data in an approved format (my energy design program imports from an xml file). Kevin.
  17. Results are in - didn't work. This was in the screenshot "Your file is already compressed incredibly well. Even our magic compression formula can't make it any smaller. Sorry."
  18. Thanks Tim, Yes I have used preview - with varying levels of success (sometimes it doesn't seem to make any difference at all). I have uploaded a 9MB file for testing to smallpdf.com - still waiting for the result. Kevin.
  19. Seve, I have a T520 printer which I have set up for wireless access and after an initial fallout with HP (and Mac) I found the solution to the page rotation problem. My printer is a 24" printer so it takes the 610mm wide roll (perfect for printing out A1's and A2's however the margins which you have to allow the printer to use for rotating the plot for and A2 are pretty useless so the solution is as follows: A1 sheet - prints as normal - Note the page size is 594 x 841 To set the computer up for A2 - Step 1 - In VW start a blank drawing (or an existing one - it doesn't matter) Step 2 - Go to Page setup then select printer setup and in the Page Attributes settings select the printer you're having the problem with and go to manage custom sizes. Step 3 - Create a custom page size at 594 x 420 (note the 594 goes first) and set the margins at 5mm all round the sheet and select OK. Step 4 - Store it as "A2 Sheet" or whatever takes your fancy - This will add it to the bottom of the sheet size options. The sheet is now stored permanently in your Mac preferences In VW Go to your page set up as normal For the A1 sheet - select Landscape For the custom A2 sheet - select portrait Obviously if your machine is an A0 plotter - you will be printing A0 sheets perfectly well, but struggling with A1 sheets - Using the same method as above but using 841 x 594 will create the rotated A1 sheet. I found that doing it this way allows me to import my title borders, set them as "fit to page" with 5mm margins all round. This is a Mac problem. The Windows printer driver has an autorotate functions which does t automatically. Hope this helps. Kevin
  20. The pdf file size is a major problem. When creating a file set for Planning Consent or Building Warrants, the Local Authority has a 5MB maximum file size limit. This is across the board. It is not uncommon for me to have to drop pdf resolution down to the 36dpi mark to get files below 5MB, which as you can imagine completely reduces the quality of the output file. I should be able to produce an A1 pdf file at 300dpi that does not exceed 5MB. I have found out that tiles seem to be particularly poor when exporting to pdf. The fact that email providers now easily accept 10MB files is not the problem, I am dealing with government agencies who will not permit files larger than 5MB. Kevin.
  21. I had this problem until very recently. There are two computers in the office (a win 8.1 pc and an imac retina. I also operated a Net gear NAS server. To cur a long story short the problem seemed to fix itself after two things happened. 1. OS 10.10.3 had an incremental update 2. I had to upgrade my NAS server to a brand new Synology diskstation DO 14 Suddenly the system started working properly. I am convinced it was an OSX system problem that was sorted in the most recent update.
  22. Jim, If you are looking at the dormer tool. Can you please look at it properly, including the following: For example: A Dormer will nearly always have a window in it, so put one is as default and set at a predetermined height - don't care what it is as long as I can change it relative to the finished floor level. If I don't want the window - I can just remove it. This would also mean that you have to fix the laughable roof tool, which really is a bit of a joke. On the edit roof element dialogue box: Centre vertically - OK but from the dormer eaves level, not the top of the dormer - This is a turn out size depending on the width of the dormer, offset and roof pitch / type Offset from top - Totally useless - Should be Offset from roof bearing level (and should relate to the top or cill like a standard window) Height Offset - Should be from the roof bearing height (come back to later) Also, if a standard window can be included in the dormer - it can be scheduled. It is currently impossible to schedule dormer windows. - Would also include roof lights in this as well, but you would then have to include them as standard windows (could easily be overcome by including standard window profiles) The offset from corner should be from the building line - not the roof edge and should also be move dormers / roof-lights along a roof by a predetermined distance relative to a setting point of my choosing Slopes: No problem Width: No problem Depth: No problem(never used it) Height: Again - should have option to be relative to roof bearing level and not just the roof plane. Roof plane is really a turn out Should have the option of being able to include a bargeboard (of my choice of size) Things missing from the dormer tool: Eaves detail - Facia / soffit - Also, will quite often not be the same as the main roof (defaults from main roof could be included - as long as they can be edited) Also when installing windows in dormers, it again is very common to set the dormer with a 0 building line offset. In this scenario, the roof profile should by default be broken to allow the external wall to continue up the main elevation or we should have at least have the option of "breaking the roof". Now the roof tool: For all but the most basic of shapes and profiles the roof tool is pretty much useless. I am not talking about the freeform NURBS tools, which are great and the ability to create stunning parabolic roof shapes - which are all great. I am talking about being able to create a simple roof with a couple of simple features - like having a gable end on the same plane as the gable of the main roof - just fails. The only way to create that type of roof is to manually draw a polyline around the building and at the gables end create a dog leg which recesses by the same depth as the gable overhang, trace round the gable and rejoin. Doing this creates the roof but does not allow for facia's soffits etc plays havoc with dormers and if you dared to try and create a section - it just looks like a joke, it also messes up the bearing height (you now have created multiple eaves heights) and in plan view - you have additional roof junctions which don't actually exist - but show. Another big problem with the roof is the requirement of having to create multiple hybrid objects so that I can show a roof and plan at the same time when designing (1.5 storey properties - which are very very common). Up till now, the only way I can display a 1.5 storey building is to draw roof and truss lines over the plans in an annotation viewport with a mask - very difficult to get VW to display what I want it to - not very model friendly!! Sorry for the rant, but VW needs to still get a lot of the basics corrected before jumping into things like Microsoft HoloLens and the like. Kevin.
  23. Does anyone know if this problem has been sorted out yet. I have had to manually put the current revision in each sheet since I started using VW - and it is a real pain. It is really frustrating because it must just simply be a record field with we should be able to reference. It is also interesting that you can only have one instance on the :rNo or any other revision data on a sheet - Why???
  24. Solution Found. Haven't been on the forum for a while, but I found the problem - and sorted it. It has nothing to do with the rendering whatsoever, it was the wall construction. I had a fully detailed wall make-up specified in the houses and the breather membrane was the item which was causing the problem. It seems that VW keels over if each of the components does not have minimum thickness. Normally you would put a thickness of 0.1mm for membranes (so that they don't add to the overall wall thickness), but VW requires a thickness of at least 1.0mm or something goes wrong. Kevin.
  25. Jim, I have attached two files. 1st file - "fast renderworks" from the design layer of the root file 2nd File - "fast renderworks" from the main drawing. The output was meant to be a "realistic render - but the two files show well enough the difference between the original and referenced file. BTW - There are 11 house types referenced into the main drawing with 78 referenced viewports to create the whole drawing. I have attached a dropbox link to the two files. https://www.dropbox.com/sh/x2ruc1i5gx1qsy8/vMBqIYoGkF Thanks, Kevin.
