Moving trimed curves in a sketch changes the curvature

[Anonymous]

Im in the middle of making a sketch via lines, arc´s and 2 trimed ellipses ( need part of the ellipses ) to create a profile i will later use to create a 3-d object by rotation. I have also rotated the lines 45 deg. in a plane. Now I just need to move alle the lines a bit to the right, but doing so changes the curvature of the two trimed ellipses.

It could be a limitation or weird defect but we'd need to see the sketch in order to test it.

Is there a specific reason you are moving the sketch items?

The reason for moving the sketch items is simple.

it consists of two ellipses there centerline and bounding boxes a line to
connect them from
one to the other and 2 curves. this construct will then be trimmed and
rotated 45 degres, to
form the profile for the cutting edge of a router tool. then moved the
correct distance from
0,0 and revolved to form the router tool.

to create the bounding boxes of the ellipses it was easy to make them
before rotation to 45 degres.

How do i send you the sketch ?

BTW. construction lines are converted to standard lines when saving a
sketch as a DXF file. ! ?

Best regards
