chris wanted to do bim. how does it work with 2d data transfer between two applications and operating systems?

and?

troy, that's interesting. i've read about exporting particular objects to ifc, but i haven't found this functionality in the v2012. where's that exactly? if you mean assigning the ifc entities: yes, it has been done. no, it was a file from scratch. i'm just examining the items one by one. i suspect that the elements overlapping stories or layers may be the reason, but i must be sure of this. i must check this one. how can i recognize the autocad line type? thanks for your time. rob

ok, but it doesn't help me now. i try to handle the clash detection with my design consultants in the first place. whether it comes to the simulations or not, it's the next issue. rob

additional to the previous post two solibri screenshots with those walls... the balustrade elements haven't been all assigned to ifc yet... rob

hi, i've just encountered massive ifc export troubles, even with items that should cause none. the main issue are the ground story walls, the one writes and exports ok from vw, the other one gets strange features, although it seems to display ok in solibri. both walls are the same insertion in vw, and assigned to the same entity (ifcwallstandardcase). the false wall doesn't get recognized as a wall neither in archicad 16 nor in revit 2009 (archicad screenshots - the wall turns to library object). i would generally want to know how can i manage the ifc file generation from vw. from this one small project, where i was forced to do an architecture type i can't really be proud of, i'm additionally stuck in a mess of chaotic ifc appearances without any clue of what's going on. further issues: the chimneys don't export to ifc at all (although assigned to an ifc-entity), the top-plates and accessories as well, the rafters cause import errors in archicad, either as ifcroof or ifcmember (framing member) instances, the vertical balustrade elements export as unknown entities in ifc and many more. what are the rules, maybe i'm missing something significant? can anybody help? thx in advance, rob

Perhaps that was a mistake. Perhaps they should have put all resources into kernel switch and optimisation and wrapped it all up in one release. then we probably wouldn't have push-pull until today... i'm curious, too rob

ok, so let me explain it in a more illustrative way. we have: 1. the proprietary bim-authoring tools layer (revit, archicad, vw, bentley, digital project, allplan and the likes) with their databases 2. the proprietary bim-analysis tools layer (ecodomus, ies ve a.s.o.) and there in the middle is the most important layer for the bim environment: 3. the middleware one, enabling _any_ communication and thus collaboration and data exchange (ifc, ifcxml, gbxml, bimxml, xls, the xml itself, gst - geometry simplification tool and many others). speaking of 'silo'ing' of any of the standards under the #3 equals the misunderstanding of the whole evolution. adesk, as they are the topic here, too, after the initial energy input for the ifc development started to sabotage the format, and in the end excluded the export from the revit lt features. ifc is an unwanted child at adesk, and they don't even try hide it. the adesk ifc exporter has been made the open source, and eventually the users implemented this feature in revit lt themselves. the tool (which is the topic here) still lacks gbxml and point cloud exports and the workgroup capability. if it is not an ignoring of the open bim direction than i don't know what is this in the end. i agree. nemetschek may have their own politics, but eventually they will have to contribute to the #3 layer in my above picture. otherwise they are the history on the bim-market. agreed again. all i expect from nemetschek is to develop the full bim-authoring capability, and to contribute to the bim middleware. rob p.s. i write this on the fly, sorry if i miss any point from your post.

The art only gets you into the front door..then the rest is up to you and the team of consultants. And who better than ENGINEERS to Analyse and Optimise D&C IMO,MATE, not your BIM, your BIM is now being replaced on large projects. Clients are now realising, its far better to have the entire team on the same program. Sketched in VWs and D&C in Revit to me is a personal insult/shame and what's NAG doing about it? My2c bim is about cooperation, not unification. i (do/will) always regard the proprietary and 'in silo' developments as couterproductive, even a sabotage of the bim idea implementation. bim in architectural practice rob

lidia, there's a strange grouping in the 3d view: the wall between the corridor to the bottom bedrooms is glued to the piece of furniture in the bottom-right bedroom. the selection shows it in the 3d view, in the top plan view it's ok. the ungrouping divides the furniture and the wall into simple lines. something is really strange with the walls. rob

everybody tries more or less to catch up but the best professionals will lead the bim processes. and it's ok so, as long as nobody's role is ignored. what i disagree is the excluding of the open bim principle. the deliverables' standards must be vendor and authoring software independent. the o&m processes may last for a few decades, probably much longer than the proprietary generated file formats. the bim interconnecting 'communication middleware' must be accessible to anybody, no matter what tools they use. rob

apparently you have something against the artistic and aesthetic parts of the man-built universe. 'the next generation of engineers' doesn't necessarily mean 'better suited to fulfill the human needs'. rob

are you on a mac or on a pc? what are the specs? rob

i make much use of the colours for the design layers organization in order to differentiate between the design options. the enclosed screenshot shows one set of the layers for the final delivery, but if i have many design options there are more colours. in this way i see instantly which layers and when are to be displayed. rob edit: the project is a pre-stories one...

sorry jeff, i've missed this one. i know about gbxml in vw 2013, now i read about the scope of ies with their virtual environment. it seems to be good news. can you please expand on this a bit? thx, rob

i can't follow why open bim should negatively affect efficiency. the inefficiency of the construction industry lies in the lacking communication while performing the processes. the owners communicated separately with the designers and the contractors via contracts, and that was it. further communication was not present because there were neither the incentives nor the mandatory necessities. in order to change this state (causing, according to the surveys, up to 35% waste in the material, time and money) the three-tier contracts with goal profits for every stakeholder, enabling the collaboration from the earliest possible phase and the open standards for better information exchange have been conceived. the efficiency in selling the proprietary software and formats is really built on sand, and not what healthy free market (if it was existing, which it isn't) wants. the efficiency must be sustainable and green, even if the contribution to it may mean lower selling rate in the first place. autodesk, for instance, are developing two simultaneous ways of interoperability: the ifc in/output and their own revit api for handling formats. being an open bim advocate i am aware i'm not very objective, but i'd like to hear counterarguments. rob

but the allplan is here ahead: ifc 2x3 v2.0 certification rob

any further information? maybe an omniclass export? does anything happen here? rob

after reading the links i realize that the case is more serious than i initially presumed... rob

hey guys, can you please provide the vw2012 versions of the testfiles? thx, rob

ion, many thanks. that was it i can't recall why they were 3d, but that was exactly the case. rob

ok, here's the file (vw2012). the left part is the remaining symbol instance trace, to the right the copy of the initial block before turning to a symbol. rob

hi, i've just tried to make a custom title block for my projects, according to the vw resource 'Creating a Custom Title Block in Vectorworks Fundamentals' and a video (of the vw2008 version): custom title block (video) the trouble is that after the creation of the texts, outlines and data record, the created symbol loses all line geometry, only text blocks remain. even if i edit the 2d component of the symbol, adding the missing lines, the result is the same, all outlines are gone, either. the 2d geometry is all screen objects, i've tried with single lines and the grouped outlines, but to no avail. does anybody have a clue what's going on? thx, rob

anything new here? how about gbxml usage (i don't have it yet)? how about 3rd pty tools? rob

afaik it's enough to install the latest one. correct me anybody if i'm wrong. rob
