Exporting point information

proed

Moderator
Hi.

We have a complex assembly with hundreds of points in the components (placed along helical paths, etc...)



The thing is - we want to export x, y & z co-ordinates for all these points - how can we do this quickly?

- and then update the information if some of them change position?



Thanks in advance

Here's a method I've had success with:



1. Export an IGES file of your assembly (single file) (and check the points box!)

2. Open the IGES file in a text editor

3. look for lines starting with 116

4. Copy these lines into Excel and clean them up



Here is a sample line:

116,1D1,2D2,3D3,0; 249P 125



in the above example:

166 is the IGES entity type for a point

X = 1E1 =10

Y = 2E2 = 200

Z = 3E3 = 3000



I think I have a batch file around here somewhere for parsing out points from an iges file... If I can find it, I'll upload it here.

Couldn't find that file, but I wrote a similar one:

(We need this functionality here every so often)



This batch file will read in an iges file and then spit out the datum point x,y, & z values in two different formats... CSV and IBL (which can be read directly back into Pro/E)

Oooops!



Don't use the batch file above.. it has a small error in it that can yield extra points in the output files...



Try this one instead.

Thanks for the help again, Brian...



We were able to get the point data manually - will try your batch file in future,

Just found this - was looking for something similar. I
took the liberty of riffing on your script. I added the
capability of exporting Pro/E .pts files. The trick is,
I wanted to retain the *names* of the point features
(which are in fact preserved in the IGES file). Improved
script uploaded!
