  1. I am unable to get the viewport from clip cube to work. I have 'display with clip cube' ticked when I create the viewport but it always appears on the sheet layer without. I'm sure I am doing nothing wrong VW2019 SP3.1, Windows 10

    Bridle tool problem

    When I create a bridle (simple 2 leg to a structural member in this case) the auto select tool picks the correct objects as below: But when the bridle builds it is at the wrong height: Am I doing something wrong? VX2019 SP3.1 Windows 10

    LED wall looks dim, truss looks basic, no detail

    you have the 'simplified' class visible for your truss. Hide this class in the viewport proprieties and your truss detail will return

    Modelling an LED screen

    *similar disclaimer* I am also not an engineer Here is a demonstration of my theory. On the left is a truss object created to be the same weight and dimensions as a theoretical screen . It has a rigid cross section because as near as damn it that is how an LED screen behaves. This is coupled to the truss using a truss link with a rigid cross section (mimicking say a half coupler*). All but the end two links are in compression and have failed. In reality this would prevent the truss from deflecting as expected unless you were using a pliable method of supporting the screen (spanset etc). On the right is a distributed load of the same weight showing the correct deflection of the truss. So in theory: If I use a rigid connection between header bar and supporting truss, I prevent the truss from deflecting. Which braceworks cannot model. If I use a soft connection between header bar and supporting truss the load will be almost exclusively applied at the outer most connections where the deflection of the truss and the screen are equal. Now in answer to my own original question: I have spaced my mother grid and the hoists that support the circular truss to minimise the variance in deflection around the circumference. I have achieved this without the need to apply any chain shortening as without load cells this will be wildly inaccurate in practice. This means that in theory none of the supports between screen header and circular truss should be wildly in compression (the screen here is modelled as a distributed load applied direct to the circular truss) : There are factors like for instance adding additional hoists which can cause this deflection to vary massively and in this case chain shortening is the only option to restore the desired flat support truss: My conclusion has been that to most accurately match theory to practice, my truss deflection must be as uniform as possible under FEA like Braceworks. Excuse the lengthy rambling post but (especially given recent events) I am taking a personal (and have been asked to take a corporate) interest in the rigging of LED screens and am interested in peoples opinions. I'm happy to have holes picked in any of the above or to be proven completely wrong! *Pro Burger for those on the other side of the pond

    Modelling an LED screen

    I've a relatively complex rig where I'm very close to my loading limits for the roof. One of the key elements of the rig is a large circular LED screen suspended from a circular truss. Currently I have the screen modelled as a series of point loads, one for every pick up on the screen header bars. My though is that this in no way reflects how a screen actually behaves as it is an inherently rigid structure attached to one which deforms under load. Could I produce a custom 'truss' which replicates the screen header bar but has a rigid cross section and the same weight/m as the screen itself. This could then be 'attached' to the circular truss using multiple pliable truss cross points to give a more accurate transfer of forces (the screen header will be rigged using round slings from the truss) Any thought would be gratefully received
  6. I have been struggling to import a DWG model into VWX. this the result of an import into VWX2019: And this is the same model imported into VWX2018: There is a lot of detail missing from the 2019 import but I haven't changed any settings away from my normal import process PC system

    2019 SP3 strange DWG import behaviour

    solved - for some reason it had been set to convert all objects to 2D

    Viewport from clip cube not functioning

    Thanks I've worked out that clip cube only works with OpenGL and RW rendering and also appears without the clip cube until it's rendered
  9. When I convert my trusses to lighting positions they no longer appear in my truss count worksheets. Am I doing something wrong?
  10. Brilliant! That menu has always evaded me. It's not very obvious. Thanks
  11. Thanks Is there a way of adjusting this property once a worksheet is generated?

    Vectorworks 2019 SP1 Updater Not Working

    I have been in touch with tech support and they have provided me with links direct to the installers for for Vectorworks Updater, once installed this works fine for SP3 although I had to insert the license number myself Mac http://release.vectorworks.net/nnapub/updaters/24/NNA/eng/app/Vectorworks 2019 Updater-24.0.477321-mac.zip Windows http://release.vectorworks.net/nnapub/updaters/24/NNA/eng/app/Vectorworks 2019 Updater-24.0.477321-win-installer.exe

    Another problem with trusses

    You'll have to build your own spacers, the prolyte spacers in the libraries do not work

    The problem with the simplified display of trusses

    that rotation also happens randomly sometimes when connecting trusses, especially at corner blocks I think I reported it as a bug a while ago

    Vectorworks 2019 SP1 Updater Not Working

    SP3 and updater still does not work
  16. I know it's going to be a simple answer but I can't work out why the attached does not work. I'm expecting an extruded rectangle centred at 0,0 with a BotZ of 0. The extrude and rectangle parts work but once I add in the maths to make the centre 0,0 it all goes wrong, the debug tool doesn't seem to do anything. Help! screen marrionette.vwx
  17. Thanks Marissa that's great

    Hole in a Stage plug

    I think you will have to un-group the stage plug (it will no longer appear in reports etc) and then you can use a solid subtraction. (you must be in a 3D view when you un-group otherwise it will only give you the 2D components)

    Rotate Lighting Device Like a 3D Symbol

    you can also group the lighting fixtures to rotate them but this will not work for the truss

    Rotate Lighting Device Like a 3D Symbol

    Is is not possible to rotate hybrid symbols like lighting devices in this way. Do a quick forum search for 'create plot and model view'. There are plenty of threads on this in the entertainment section of the forum This tutorial is a good place to start.

    Single house rigging points

    THIS! Link to your request and I will support. It's such a common scenario. Hoist top hook snaps to house point and low hook to truss would be great

    RENDERING RECESSED LIGHTING LED

    Your Glow should be contained, it should not wash out your scene like this. Here is a simple glow texture (at 300%) in a channel, is this the effect you are trying to achieve?

    Audio array tool

    I'm still assessing whether braceworks is worth the investment and whilst playing around have found the following problem. If you have an array utilising more than one bumper, only the top bumper is included as a load. See here where I have selected the whole system, the second bumper is ignored. In the OIP there is no option to 'include in calculations' or name it as a load.

    Problems importing large DWG files

    HI Nina I can send you a dwg that I had problems with. It could well just be a problem caused by sloppy production on the other end of the process, I've had wildly varying success with dwgs from clients. I will message you with a file link.

    Problems importing large DWG files

    I've also had problems with large DWG imports (like large urban plans in 2D). 100% CPU usage on one core for 45min + until the import is complete. Generally this is in the last few numbers of the progress counter. I've also had to go back to 2018 to avoid some strange scaling issues when importing the same file.
