bikengineer Posted March 26, 2012 Share Posted March 26, 2012 I am trying to draw a bicycle frame in 3D. What is the best functions to use? I first drew the frame in 2D using regular lines. Next I drew a circle at one of the intersection points, then used Sweep. I repeated the steps but with a smaller circle. Next i was planning to Subtract the smaller tube with the large to create a tube but I am having trouble selecting to subtract to make a hollow tube. I'd like to revaluate to see if there is a easier way to draw so that it is easy to modify down the line. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted March 26, 2012 Share Posted March 26, 2012 Use _REGION on the two circles and _SUBTRACT prior to sweeping. Quote Link to comment Share on other sites More sharing options...
rkent Posted March 26, 2012 Share Posted March 26, 2012 Solidedit > Shell will work and you don't have to draw the extra circle, extrude, etc. You can also draw a circle at the end of the tube and use PressPull to subtract. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted March 26, 2012 Share Posted March 26, 2012 Sweep of region is the far easier method - see http://home.pct.edu/~jmather/content/CAD238/AutoCAD%202007%20Tutorial%208.pdf Quote Link to comment Share on other sites More sharing options...

JD Mather Posted March 27, 2012 Share Posted March 27, 2012 Not just opinion - it is fact. I assume the frame is more than one tube. I assume there might even be bent pieces. There might be multiple sizes (diameters) of tubes. Quote Link to comment Share on other sites More sharing options...
