Persistent tag for Vertex

Persistent tag for Vertex

Hi,
Can we have unique identification for Vertex in ProE like we have Persistent Id for ProEdge / ProSurface etc?

What is the work around if we want to have a unique set of vertices obtained from a list of Edges which share common vertices?

Thanks in advance,

Regards,
Pradnya

Pradnya,
Are you trying to compile an array of uniqe vertices? In other words if
you had a rectangle with edges A, B, C, D and vertices 1, 2, 3, 4. When
you visit edges and vertices you would get an array like this:

(1, 2), (2, 3), (3, 4), (4, 1)

And you want:

1, 2, 3, 4

Is this correct?

If so then you just have to do it programmatically. Pro/TOOLKIT does
not contain a function that will give you a unique set of vertices.

Pradnya,

It depends on what you are looking for.



1. If your program wants the endpoints then call this function
twice with t=0 and t=1:

a. ProEdgeXyzdataEval(edge, 0, xyzPoint, deriv1, deriv2,
dir);
b. ProEdgeXyzdataEval(edge, 1, xyzPoint, deriv1, deriv2,
dir);

2. If your program wants the points on the edge according to t then
you need to call ProEdgeXyzdataEval from t=0 to t=1.0. Each iteration
through the loop will increment t by some factor. You have to determine
the factor yourself in the program.



For more information on this look in the API Wizard under User's
Guide->Geometry->Evaluating Geometry->Evaluating Faces, Edges, and
Curves. Basically you are asking Pro what the point is at t=n for the
specified edge. You can pass null for the derivatives and direction if
you are not interested in them.
