Loft Problem

HELP!!

I'm trying to create a lofted part. This is complex shape with several
cross sectional profiles.

I created sections 1 & 2 and added a circular path. It doesn't follow
the path, it lofts in a straight line. If pick my circular path, I get
an error, "Loft sections must all be closed or all be open. Mixed
cases are not allowed"

Then I created section 3, and all I get is the following message: "The
feature could not be created because it would produce self-insercting
geometry"

What do these messages mean?

 

The closed and open message means just that, you have to have either
closed or open loops as sections, but you can't mix and match. If you
don't know what a closed or open loop is, you've got some homework to do.

If you're trying to make a loft that loops back on itself, you'll have
to use the "closed loft" switch. I think you need at least 3 sections to
do that.

Are you sure you put the circular path in the guide curve list instead
on with the profiles?

Self intersecting geometry can be caused by just about anything, from
connectors to tangency to selection order or location. It just means
that the geometry would run into itself if created, which SW doesn't allow.

Really, you just need some basic loft help. The SolidWorks help file
and online tutorials are two places to start.

If you want something specific, you will need to post an image or a
model somewhere.

good luck

 

Do you have permission from com.com to use their domain name as your own?

 

Did you specify the circular path as a centerline. This will give you
quite the different path than a guide curve.

Sometimes it works better to try a Surface Loft rather thatn a Solid one as
surfaces can be more forgiving in this area I find. ONce you have your
lofted surfaces you can then cap the ends and knit to form a solid.
