Instrument Heights on Angled Hanging Truss

[aleverda]

[font:Arial]I'm trying to create a plot with truss hanging on an angle where the back dead is at 3000, front dead at 9000 when in side view.

So far I have converted said truss with appropriate hanging angle in 3D to a light position at Z height 3000.

Assigning the instruments to the truss they assign to the truss but remain only at a Z height 3000 regardless of placement.

I wish to make an accurate rending of this plot and hope for the instruments to reflect the correct dead.

See attached image for further clarification

Any advice?[/font]

Hi

Best not to use the hanging angle for the truss as this does indeed cause this problem if the truss is converted to a Light Position... The instruments will pick up the Z value of the light position,

Instead, you need to leave the Truss with a hanging angle of 0. Convert to Light Position and then run Spotlight/Visualization/Create Plot and Model view. This creates two design layer viewports, on different layers, of the Light Position - one of which you can rotate to be angled as you want, the other can be used to display the Top/Plan view.

Then, create approprite sheet layers with Viewports to display the design layers (and their design layer viewports) as appropriate.

Hope that gets you started. Try running the command on a single light position in a blank file, to get your head around what the command is doing.

Thanks Tasmin.

Still getting a little used to the "definition layers" thing!

When was this feature added?

It was added in VW 2009.

Beware that the height of the actual instruments isn't being changed, only the position of the design layer viewport. So the draw beam feature won't work correctly. Ditto with turning on the beam to render.

If that's important to you, then you might try classing the boom instruments by height. Then you can put them in the correct 3D position and use multiple cropped viewports to get the 2D position you want.
