dimensioning an elipse
dimensioning an elipse
(OP)
I am probably overlooking something obvious but when I try to dimension and elipse in drawing page it says cannot convert to line or arc thus I cannot finish my design because I cannot get the dimensions on the page. All advice appreciated. SW2007

From the drop down menu "Insert", select Model items - you can then select a "source". There are several different options that you can select, and this may help.

In sketches, SW ellipse entities already have points at their major and minor diameters. In a drawing, an elliptical edge does not have these points. However, if you use "Convert Entities" in the drawing to create a sketch curve of the ellipse in the drawing view, you will have points to dimension.

Thanks for the tip. I used to dimension an ellipse by temporarly turning on the sketch in the drawing which allowed me to pick the quadrants to dimension the major and minor axis. You way is less clicks.
Thanks,

Along these same lines I am having an argument with my boss on how to fully define the ellipse. If you dimension the major and minor axis is it fully defined? Do you need to specify that it is an ellipse on the drawing?
Any help would be great.
Thanks
RE: dimensioning an elipse
Major and minor diameter fully define the size of an ellipse. Location can be made to ellipse center or tangents. If ellipse is not "square" to the drawing, you may need to show the angle of the major or minor diameter centerline.
If your boss still wants to argue, have him take it up with Euclid or Newton.

Some machines recognise elliptical geometry, others need lots of dimensioned points to be able to "connect-the-dots".
