Chris,
Thanks for the reporting and telling us the ER info. SPR would indicate bugfix which they may also do if the patterns were originally supposed to work for non Line Circle Arc figures. But until then, to have equal ellipses would be cool and work for non pattern cases. it is also probably easier to achieve.
Another Workaround has a little more set up but should work better.
The third 3rd method would be to use a block which I'll try next. But my current and tested method is too Pattern two perpendicular lines with a set of (midpoint, coincident, intersect) to get a set of
Perpendicular lines and a crosspoint Pattern these 4 items (2 lines) 1 centerpoint (1 point) on (1 Ellipse) concentric (o+)
I suggest making the lines not exactly on quadrants of ellipse since those will not be maintained by the pattern. After the pattern operation you can add however many Xdir Ydir instances to place the quadrant points on the patterned lines which maintain the size and shape of the ellipse.
I will post a 2009 set up part with three sketches with 1 method each. Dimensions Before Dimensions After Block in Sketch for everyone to test out in various versions of SolidWorks you may even use it to attach to the ER as a test part for the developer teams.
Other methods of maintaining the pattern can be a set of 2 centerlines for angle and length dimensions for pattern centerpoint spacing and using Linked Dims and coincident relations between ellipse center and line and 1 quadrant and pattern direction line.
Using a construction Slot and linking in the Quadrant points of the Ellipses with arc and wall centers. You may even get the pattern axes to show at the centers.
Well SolidWorks crashed on last attempt so I'll get the model together tomorrow and post the file here.
