Non circular/rectangular pattern

Non circular/rectangular pattern

Non circular/rectangular pattern

(OP)
I have an unusal shaped flange that I need to place bolt holes thru.  I have created a curve on the flange and setup points at the locations the holes are required.  I can go in and make a hole at each point, but I am sure there is a way(easier) to pattern the hole to the points on the curve.  Any ideas?

Thanks

RE: Non circular/rectangular pattern

I'm assuming you have no planer faces on the part perpindicular to the planer placement face? If so the way I would approach this would be to orient the wcs so that two of the vectors (x-y) were coincedent(?) with the plane or face that you are using to place the bolts and the origin of the WCS at a logical datum point. Then create "3 planes of the WCS", Insert-->Form Feature-->Datum Plane... click apply (This will create X-Y, X-Z and Y-Z planes based on the location and orientation of the WCS). You can then position your holes using perpindicular positioning from the planes perpindicular to your placement plane or face. Unfortunately this method is non-associative, like the point method you are currently using.

Thanks vanishingpoint.  This would work, however I know there has to be a simpler way to go about this.  For example in Pro/E you can do the following:

1. Offset a curve associated with the edge of the flange
2. Create a datum point on the curve (Arclen)
3. Create a hole on the datum point
4. Pattern the datum point and that's it.

I would like to try to get away from creating each hole separately, if at all possible.

Try asking your question in the internal UG BBS. John Baker would see your question in the CAD conference and if anyone can answer your question, he can.

RE: Non circular/rectangular pattern

Dear Mike,

Ben's suggestion is a good one.  You might be able to find out some good info from John Baker.  He is the best.  But, unfortunately from my experience there is no capability in Unigraphics such as that you described in Pro/E.  Funny that even SolidWorks has this capability that UG doesn't.  That's a statement coming from a die hard UG proponent.  One suggestion that I woulb make to make the hole placement associative is to create smart points at the locations of hole placement by using either datum csys at those locations or by projecting the points onto the face so when the point locations change the holes will change also.  Lastly, I would recommend you submitting this as an enhancement request to GTAC on the EDS GTAC Support Site.

Best Regards, and let me know if there are any other questions that I may be able to help with.

Thanks for the comments.  What is the UG intenal BBS and how do I post to it.  I've gone to the EDS web page and cannot seem to find it.

Thanks
