Sketch Projection

I can't think of anything better than to extrude a body up to the 45° plane, then convert entities from the top of the extrusion.

I'll be curious to know if there's a better way.

Have you tried right clicking (or Ctrl-C) the orignal sketch in the feature tree and pasting it on the plane you want it on?

Sorry, my method doesn't do what you want. The other guy had it right.

1. As noted in a prior thread from me yesterday, where I had a similar question, users pointed out that in the Extrude box, you can pick not only the surface to extrude to, but also a Vector (axis for instance), that is NOT perpendicular to the sketch plane.

What I found, though, is that using a Vector to direct the sketch, you must extrude to a solid body (even if it is temporary and then deleted), as in SWks 2004 SP5, I can't make the vector extrude to a plane (so I put an object on it).

1. Us Sweep and a Path curve or line to direct your sketch the way you want.

Good Luck - Bo

You can do a extrude from sketch1 on the top plane upto the 45deg-plane (upto surface). Then add a sketch on the 45-deg plane and convert the entities from extrude1. After this you can hide extrude1. Isn't this what you want? \/\/im

Yeah, it works. I extrude along a sketched vector and then create a new sketch and convert the entities. Even though it works, it's not very "clean", you need to hide the protrusion. I would have prefer to do it only with curve entities. Solidworks doesn't have a lot of options regarding curves and references geometry, I think. Thanks for your help.

One way is to extrude the sketch as a surface, (kindof like dropping a curtain), then do an intersection curve where the resulting surface meets the 45 deg plane. If necessary, you can then convert the intersection curve to the plane so you have a 2D sketch to work with.
