Help Sweep with expanding OD circles

Help Sweep with expanding OD circles

Help Sweep with expanding OD circles

(OP)
For the life of me I can't get this to work.  What I am trying to do is draw a 3" OD pipe (.065" wall") elbow that gets swedge up to 3.25" OD after the bend.  I don't want use a loft as it cannot be dimmensioned correctly enough for the pipe bender.

The problem comes into to play when trying to use a sweep I cannot seem to get it right, as it just produces errors when selecting the guide curves or sweeps to the first point on the guide curve.

I've done some testing using an eclispe and it works fine.  The problem only exists when using a circle.

Any help is appreciated.


 

RE: Help Sweep with expanding OD circles

Add Split Points, to the circular profile, where the Guide Curves connect.

BTW, the outer arc and line are not tangential.

cheers

RE: Help Sweep with expanding OD circles

You don't need to split the circle.  Add a point coincident to the circle, and constrain the point to a guide curve usinge pierce to circle's control radius.

TheTick,

That was the first thing I tried, but it would not work for me. Using tha89sx's file, does it work for you?

cheers

RE: Help Sweep with expanding OD circles

Also constrain the senter of the circe to main guide with pierce.  It has worked for me in the past.   

RE: Help Sweep with expanding OD circles

Tick ... Are you able to get it to work using tha89sx's upload? I don't remember what version you are using.

The only way I can make it work is to split the circle where the guide curve connects. Maybe this is a SW2009 regression.

cheers

Thanks everyone, by splitting the circle it worked out.
