distance between point and surface

distance between point and surface

distance between point and surface

(OP)
hi
I'm trying to calculate the minimal distance between point and surface in the case of that its not possible to do an orthogonal projection of the point on the surface.
is there anyone who can help me?
thanks

RE: distance between point and surface

If there is no possible orthogonal projection of the point to the surface then there may be one to a boundary curve. Failing that, then there will be a minimum distance to a corner point of the surface.

hello kapitan
of course thats true, but the problem is how to automate this steps!! have you an idea about that?

RE: distance between point and surface

Are you using CATIA, if so, is it V4 or V5 Release what ?

Or is it some calculation being done in a program ? The question is too vague at the moment to do much with. Maybe the surface exists as an equation ; Z = f(X,Y) or whatever, or is it in a CATIA model. We don't know yet, more background information required.

ok, Im using catiav5 R10, the surface is sweep or extruded surface modled with catiaV5, and the coordinates of the point are knowen. so I just need to know witch method or functuion to use to calculate my distance!
thanks

RE: distance between point and surface

I'm using V5R9 and I doubt if R10 is much different for doing this,
