I am designing formers for an rc plane in coreldraw9. I have created the shape and made a duplicate to shrink and put inside the original.. When I resize the duplicate by using corner handles and put it inside the original, I do not have an even distance between the two objects. Same thing seems to happen if I use the docker for scaling. Am I doing something wrong in using either of these two methods?
use Contour Tool (CTRL+F9)
sample - magenta original curve, black curve - outside contour
Another way*:
Duplicate original object
Add outline to duplicate objects (with width 2 times bigger than required offset)
Convert outline to curves
Create boundary (Arrange – Shaping - Boundary)
Delete duplicate object
*on CorelDaw version where function Arrange-Shaping-Boundary applied
