Split Curve

Hello everyone,

i'm new in ICEM and i'm with some problems to split a curve.

I imported my geometry from Workbench (Desing Modeler). I need to construct an o-grid, I have 4 circles (curves), that form tubes, which are not allign to the global coordinates (inclined). I'm confused about place 4 edges (supposed to form a square) inside a circle. How can I allign the edges to make an 90º angle between them?

First, I had an idea to split my circle in 4 points and associate the vertex to the points. But I don't know to split my circle (curve).

Anyone can help me, please?

Thanks.

Here is a picture of my geometry. I need to certify that the angle between the egdes are equal to 90º.

Usually, that is close enough ;)

But if you want to be sure, you can go to the geometry tab => Create/Modify Point => Parameter along a curve. Type in a number like .25 or .125 to get a point in the right place. Then add 0.25 to that to get the next one, etc.

You don't actually need to segment the curve, but if you wanted to, that would be under Geometry => Create/Modify Curve => Segment Curve.

Then go back to blocking associations and associate the verts to the points.

Best regards,

Simon

Hello Simon,

I just made a test and it seems to work very well.

When I did the associations, the angle was not equal to 90º. All the vertex was at the same point, and I fix them by moving freely. That's why I need to be certain about the angle.

Thanks a lot! I was very helpful.
