I haven't really tried to add welds to an assembly model before, and have always entered them manually in the drawing. So I'm taking a stab at a little Monday morning learning and I'm a little perplexed how to position the weld properly. In this example, I have a coupling that is being welded into a section of L shape steel. I want an intermittent weld - two 1/4" welds centered at 0 and 180 degrees. selected the face of the coupling and the face of the L shape to position the weld bead. I had to use a calculator to find the circumference of the hole in the L shape, subtract 1/2", then divide the remainder by 2 to manually enter the weld gap (why this is not calculated automatically, I have no idea). So this part of it worked OK.
Positioning the weld is another story. Changing the From/To variable creates a mess. As you can see in the image, this is where the weld bead ends up by default. Any suggestions?
