Getting a datum point's coords in relations? 2

[HelterS]

Hi all,

Many of the algebraic expressions I use in my relations require the 3D coordinates of specific datum points in my model. At the moment I'm using an analysis feature containing a distance measurement to obtain each of the datum point's 3 coordinates induvidually.

This seems like an inelegant way of doing things?

Is there a simple lookup function that I could use in relations to achieve this more efficiently?

e.g. something like Coord(Pnt16).X ???

HelterS,

You could use a PTS Output File Format

The format of the Pro/ENGINEER point (.pts) output file allows it to be read in during the creation of datum point features. I've used this to read in some complexe gerotor geometry that I obtained from another math based program.

Thanks but outputing files to disk isnt really elegant either.

I have made some progress through. I was previously using 3 induvidual measure analysis features per datum point. However I see that if you just measure the distance once and then go into the definition there are 3 normally turned-off parameters: DISTANCE_X , DISTANCE_Y, DISTANCE_Z. If you turn these on you only need to do one measure analysis feature per datum point which is pretty efficient!

Here's an improvement on the way you're doing it, step by step.

1) Make the analysis feature. Name it P1_COORD
2) Set it to be a Measure type, hit next
3) Pick the Csys and the point as references, except now, under Projection Reference change the type to Coordinate System, and choose the same Csys you are measuring from.
4) Press Compute again, then press Close.
5) The Analysis feature will now make 4 parameters: DISTANCE, DISTANCE_X, DISTANCE_Y and DISTANCE_Z. The last three you need to change the Create option to yes.
6) In your relations, you can now use the syntax--> DISTANCE_X:FID_P1_COORD
