bmckelvie Posted November 17, 2014 Share Posted November 17, 2014 (edited) I have been trying to make a hole pattern along an ellipse and I'm getting some rather unexpected results. My procedure is; I have made a 2d profile of the ellipse that I want the holes to be placed on, then I drag a hole to the line and tell it to link along the curve. The first time I try, IronCad simply does nothing, the second time it makes a small cluster of overlapping holes. So if there is a better way of doing this I would love to know! I am attaching a video demonstrating what is going on. Thanks Brent *edited for grammer ironcad_ellipse_holes.mp4 Edited November 17, 2014 by bmckelvie Quote Link to comment Share on other sites More sharing options...
ysinitsyn Posted November 17, 2014 Share Posted November 17, 2014 Use the edge of the elliptical shape, instead a sketch. Or extract the 3D Curve from the sketch and use the 3D Curve as a trajectory for the pattern. Quote Link to comment Share on other sites More sharing options...

An elliptical path with the holes positioned incorrectly on it, as well as the holes positioned on the outside edge of an ellipse with the first hole offset incorrectly. I made the file simply by dragging and sizing an ellipse, then 2d sketching a random sized ellipse on it. I then drug a hole to the center of the ellipse and then copied it to each point. I then drug it to the curve and told it to link along the curve with a number of 4 and a distance of 25mm Hope this all helps ellipse_test_part.ics Quote Link to comment Share on other sites More sharing options...

bmckelvie Posted November 17, 2014 Author Share Posted November 17, 2014 Hopefully this will be helpful in your problem solving, but I made a video starting from scratch of what I believe to be the same or similar odd behavior, in this video I get the holes to follow the outside of the ellipse, but they do not evenly distribute correctly, when finished they leave an wide area with no holes and two areas with double holes.
