Sweep

[ChadMH]

Can someone help with this?  I cannot perform a sweep.  Im not sure what else to do.  It seems simple enough but cant get it done.

Why would you create 3 arcs where only 1 is needed?

Change the radius to .125

What do you see?

How long are those lines when you change the radius back to .5?

Change the radius to .4999 does it work now?

You cannot sweep on zero length lines and creating zero length lines can cause all sorts of headaches down the road.

(you might get a feature that doesn't fail until you have a dozen more features and hours invested in the part - in a way, you are lucky that this one failed)

Thanks for the response but I was more looking for how to do it rather than a critique of how it IS.

[ChadMH]

Here it is another way.  Any suggestions?

[JDMather]

Did you start over or try to use the original with the zero length line?

The easiest technique is to sketch the line and without leaving the Line command click, hold and drag the arc off of the end of the line.

You can also use the arc command to create the arc from the line.

Note the difference between my arc and your arc constraints.

  Of course the Open Loop warning is meaningless since this is an open sweep path.

Line, click drag, arc - dimension.

Circle, Sweep.

I would have done an example for you, but you are using an earlier release, so you would not be able to open my example.

It seemed easier to describe EXACTLY the same steps that I went through with your file to discover and understand the behavior.

 

Have you installed all Service Packs for your release?
