Creating large amount of datum points

[vantveen]

Hi All,

From a double curved surface of a step file I want to measure the position (XYZ) of points on this surface w.r.t. a coordinate system. Either it concerns a large pattern (600 x 600) so also a lot of points (360000). In this way the surface is defined by points which can be used in an other program. As you can imagine creating and measuring points in this manner takes a lot of calculation time. Is there any idea how I can optimise this process? Maybe in combination with MathCAD?

Thanks in advance.

Regards,
Martin

There is a text data file used in The Advanced Suface type Blend created using an "Name.ibl" file.
is file divides your point data into cross sections with e same number of entities for a 600 x 600 surface this file would contain 600 groupings of 600 point 3d splines.

I did a search for
"pro engineer ibl file"

Unless the cross sections or sections are planar you'll need to use General as the Blend Type option.

The data on the following links belongs to the site creators and not myself. I posted a technique

If you have the Advanced Assembly or Analysis functionality or can create a Analysis such as Center Of Gravity from Model Analysis you may try the following method of using a point analysis for Distance Via CSYS ad then pattern the analyzed point and achieve a Refeence Pattened analysis specifying your own unique parameters for X, Y, Z and display those in a table as I describe in my below created post @McadCentral as user name "mjcole_ptc" where I also show R,Φ,Θ which I'm suprised proe/creo let me use for parameters.

I'm eager to see a mathcad based procedure.

Hi Michael,

Thanks for your reply. In the coming weeks I will try your solution.
