https://community.graphisoft.com/t5/Modeling/trusses/m-p/37170#M175221 I figured it out. The truss settings were showing 2x27 boards so the computer could not perform the operation. I changed this and it works now. Sorry it took so long to get back. I have Been in Mexico for a while.

Did you draw it and save as a 3d object? Can you post a picture? <BR /> <BR /> woodster Tue, 08 Mar 2005 22:32:06 GMT https://community.graphisoft.com/t5/Modeling/trusses/m-p/37169#M175220 Anonymous 2005-03-08T22:32:06Z https://community.graphisoft.com/t5/Modeling/trusses/m-p/37170#M175221 I figured it out.
