Circles and arcs in 3D sketches?

Circles and arcs in 3D sketches?

Circles and arcs in 3D sketches?

(OP)
How is it possible to create circles and arcs in 3D sketch mode? I'm modeling a wire grill and I need to create a semicircular lug on the end of an swept wire to serve as a screw mount. I can't figure out a way to do it with only lines and filets like SolidWorks allows in 3D sketch mode.

Thanks,

Tom

RE: Circles and arcs in 3D sketches?

If you find difficulties doing this within a single 3D sketch, you can create any entity available in a 2D sketch, then convert the entities you want into the 3D sketch.

You can also use splines and add radii between two lines for an arc.

One way to handle this problem is to cheat it by making square corners, then filleting (sp?) the 2 corners.  The trick is to to leave a .001" straight line between the 2 fillets to make it look like 1 continuous arc.

The square corner and fillet thing was what I tried first; it caused problems whe I tried to sweep along the .001 long segments. Scott's composite curve idea from the E-spring example worked great. I was able to easily combine both 2D and 3D sketches to get my guide curve and then sweep a circle along it to form the wire.

Thanks,

Tom
