[Br...] Posted January 7 Share Posted January 7 I have a large diameter disc ~ Ø13.2"x.020". on that disc, my question is in respect to 24 drilled pill shaped slots along the outer edge with a bolt hole Ø of 12.8. Each pill shaped slot is oriented by its long end in line with the center of the disc. The center of the disc has a hole, which acts as the center & a datum. What I need to do is measure the "top" and "bottom" of the pill shaped feature (Being the radius on either end), and find a symmetry point between them. (Lets call the Symmetry Point "Symmetry_B(x24)"). Then I need to create a line between that point and the center hole, to act as a Planar Rotation for an alignment which centers on that slot. and measures it in the exact same orientation around the part, in line with the center. The hard part is im trying to loop essentially every feature, for sake of time. So I create 1 feature on a radius of 1 slot, and loop is 24 times around the part. Then I do that for both sides of the slot to find center. From there I loop a single Symmetry point feature using that same 24x pattern around the part. From there I loop a line feature recalling the center hole & the looped symmetry point. (Lets call that line "2d Line_B(x24)".) Now im trying to create a looped alignment with: Planar rotation being 2d Line_B(x24) X being Symmetry_B(x24) Y being Symmetry_B(x24) The result should be 24 separate alignments each centered on a separate slot, also oriented on the Y axis, in line with the center of the part radially around the part. Is there any way to do this? does anyone have any tips or tricks for how I can make this work? Link to comment Share on other sites More sharing options...
[DW...] Posted January 7 Share Posted January 7 Are the features actual slots? Link to comment Share on other sites More sharing options...

[DW...] Posted January 7 Share Posted January 7 (edited) I am not exactly sure on what you are trying to accomplish, but the slots and lines can all be created via pattern work. Make your circle in the center. Make your slot at the top. Once you finished making the slot as defined in the user manual (I believe three hits on the length, and two hits on the width/radius), go to the drop down in the feature and select pattern. Choose Polar Pattern Offset. Set this to -15.0°, and 24 (real number). Make a 3d line by recalling the circle and slot 1. Go into the drop down and now select pattern. Choose Rotational Pattern, and select "First formula then pattern" bubble. Open rotational pattern, and set the parameters to -15° and 24 (real number). You may want to project the lines to a plane if you want to toss out any a1/a2 skewing. Is this helpful? Edited January 7 Link to comment Share on other sites More sharing options...
