2012 Revit Arch, and I need a large steel truss.

I made a truss that fits perfectly in my project but all of the webbing posts have gaps on the ends and it looks like crap in renderings & section views. Revit doesnt seem to give any options when drawing the truss, but then its too much to ask for Revit to auto join the pieces?

Does anyone have any advice on how to remedy this? I have the truss visible in a perspective rendering as it is a key component to my building design, but it looks entirely out of place when everything else has been well detailed in the rendering.

Believe I did this one with sloping columns, to get it to look correct even so the ends don't cut right. This may have originally been drawn in 2009, so the new 2012 may work better.

So you drew the webbing for the truss as columns, then set them at the approtpiate angle to look like a truss? (am I understanding you right)

Ive attached one of my renderings (hope it works) of how it looks now. (I need to fix the background too, lol)

Ive gone into the truss family and extended the webbing lines far past the edges of the truss and that seemed to work a little. Now the truss members all seem to connect, but Revit isnt too happy about it because they are overlapping instead of being joined.  I wish Revit's coping tool would work on trusses the way it does on floor supports.

I see the dilema and if you use the sloping column as your brace work, there is an option to allow you to miter the top and bottom but only at 90 degrees I think, so you can cut the bottom flat or vertical.

If you place the items as structural beams, you can use the coping function to 'trim' the brace beam to the horizontal beams. Set the coping distance to zero.

As this is the toplisted Google result when searching for truss connection problems, I figured I would post what I found here.The easy fix to get it looking correct for renderings is to "remove truss family" (which makes it a bunch of individual pieces), then select all the vertical pieces and set the "start/end join cutback" to something like -0.5'. Effectively, this just extends them beyond where Revit expects for a connection, making it disappear into the top/bottom chord.Not a perfect fix, but it works.

Hi! I had the same problem and a colleague helped me out:

1. Set work planes on both top and bottom desired lines of the diagonal web

2. Select the truss

3. Press tab and click on the diagonal element, unpin it

4. Extend start and end join cutbacks so that the diagonal element goes beyond the desired lines

5. Select CUT on the modify menu, select the unpined element, and cut with the aid of the reference planes drawn before

This worked for me, hope I explained it right!
