TrussPro Object view Problem

[Anonymous]

Using the TrussPro Object with a Scissor Chord the 3D view has a "full-panel" when viewing it it on direction. it is okay viewing it in the other direction.

Edit: this is using the Open GL 3D Engine.

Jay:

Even the top image is not correct, as the trusses show as partly solid and partly wireframe. A video card issue? Duplicate trusses in the same locations? This object displays fine on my setup.

I will look into the Video Card (ATI Mobility Radeon 9600 Pro Turbo).

There are no Duplicates.

I did not mention that I an viewing the 3D using the Open GL Engine not the internal 3D Engine (which looks fine;see Attached).

Only selecting one Truss and viewing with the Open GL Engine results are a little better. The truss is not partially wireframe and the Scissor can be seen regardless of direct of view. there is no shading though?

Can any one else confirm this?

Looking at your last image, it appears that the top and bottom chords over run each other, so their intersection creates an impossible condition (similar to drawing a slab where the perimeter crosses over itself). If you post a screen shot of your Structural Dimensions settings under Parameters, the truss length and height, and whether this part is from the ArchiCAD Library or ArchiCAD Library Special Edition, I might be able to reproduce the problem. I now suspect it has to do with the particular settings you have for this truss.

David Thanks for staying with me on this one.


Here are the Settings.

The Trusses have a 8 41/64" Heel Height because that is the True height of trusses that are manufactured (given a 2x8 top chord which is 1/4" raise off the bearing).

If the Truss Heel height is set to zero the problem does not occur. I guess I will just have to add the raised top chord dimension (1/4") to the over all top chord dimension. Which means adding 0.289425" to the depth of a top chord that has a 7:12 pitch.

Using your parameters, I get the same result you originally posted (combination of shaded and wireframe, texture panel with OpenGL, better result with Internal Engine Shading). It appears that the Heel Height parameter is for adding a vertical piece at the heel (try using a value of 2'-0" to see this) rather than adjusting the connection between the top and bottom chords, so your fix is probably the best solution for your situation. Sorry we couldn't solve this completely, but I don't see how to get the result you want with the parameters of this part.
