Pierce constraint in Pro/E and Creo?

Do anyone know how to constrain part of a sketch to geometry which intersects the sketch plane?

I've got a video here of this being done in SolidWorks: http://www.solidworkstips.com/content/index.php/solidworks-tips/46-01-pierce-relation

Thanks

Hello David

Here is short demo of Coincident Constraint

Hi Vladimir

Thanks for the response. That only seems to work with the end of a curve though. What I want to do is snap to the point where a curve intersects the sketch plane.

Thanks

Hello David

If you need move your sketch to intersect plane you can offset sweep profile with dimension or use Trim At.. functions (RMB)

Thanks, good tip.

If it was the edge of a solid or surface, rather than a curve, would it have to be converted to a curve with Copy, or is there another way?

Thanks again

Copy and paste is a good technique

To assist with this, I've attached a part. The idea is to line up the circle with the line where it crosses that plane. Would the Intersect command be relevant here?

Thanks

Hi, I'm out of the office - I will write to answer next week.

Have a nice day.

David,

Not sure if this is what you are looking for, but I have attached a model I created in WF 5.0 where I created a spline sketch. I then invoked the sketch tool again this time while setting up the second sketch plane, I selected the point command and placed a point on the first spline curve, and on the datum plane (could be any surface though). After creating the point, I then selected the datum plane tool. I placed the Datum plane to go throughthat point, and to be normal to the original spline curve. After completing this plane, I allowed sketcher to use this for the sketch plane, and then created the circular sketch. It is pretty neat when I use Dynamic Edit, I can watch the second sketch stay tied to that intersection of the curve and plane, and also observe the curve remains normal to the spline at all times.

Hope this is helpful to someone.
