Intersecting a Generic Feature

[John Kugler]

I am trying to intersect a line and a generic circle to create a point. I have tried everything I can think of to no avail. I've done pierce points, intersection points, reversing the vector of the line, etc, etc, etc. Tech support has the program and is looking into it, but I am putting it out to you kind folks.
I am trying to create an intersection point of a mesured line and a generic feature. This seems pretty straight forward, but it is not working out like it should.


Enclosed is the program.

Program has a comment at the end explaining what I am trying to do.


Thanks for any and all help in this matter.

Pierece Point

I looked at it. You want to use Pierce Point. I chaged your two to Pierce point, and PNT6 came out on the other end of the circle. PNT7 was fine. You need to reverse the vector of LINE3 and do PNT6 again. It worked for me.

Does the point come up at the point of the intersection?? I've tried everything.

What version are you using? I have 3.7mr2, I am going to upgrade to mr3 soon.

[Don Ruggieri]

Intersections

Sorry, I used v3.7MR3. Yes, the points came up at the apparent intersection. 1 was on the near side and 1 was on the far side, but they were both legitimate intersection points. I don't have v3.7Mr2 or I'd have tried that. Not sure if that's the difference. . .

[John Kugler]

OK, I give up. I installed mr3, and I still get the error. Theo math doesn't converge, no intersection point, blah, blah, blah....

I'm am soooo frustrated with this...............

This is what the code looked like -

RECALL/ALIGNMENT,INTERNAL,MAIN_ALIGN
COMMENT/DOC,NO,Here is my generic circle.

,with the generic circle.

Ok, dumb question here...

Does active workplane make a difference?

[Don Ruggieri]

Workplane

Not really a dumb question at all, but Yes, I believe workplane does make a difference. Lines and Circles are both 2D features, and require workplanes. I don't believe the construction/pierce point is much smarter, it still needs to know what workplane you are in to work with those features

[John Kugler]

There it is!!! Point 7! That is exactly what I am trying to do!!

I will try again....
