Looking for a fast and easy way to fill in a 2d object. Step 1.) Arrange 3d objects for illustration. Step 2.) Project to 2D. Step 3.) Need to fill individual parts with yellow!!!.....
The easiest way is to work with "Contour sets"
Look at here: Re: Managing details and contours in IsoDraw
Here's an extract from the manual:
About Contour Sets
A contour set is a named collection of 3D objects, such as parts in a subassembly, that are highlighted with the same color when you project them to 2D. The highlight is a flat-shaded color fill inside each object’s projected 2D contour.
1.You can use the fill color tool in Palette window for a closed path.
2.Second way is, duplicate the part and make a bezier path of outlines of the line art to be filled and fill color with fill window.
later place the filled layer behind the original line art.
I would suggest you to create a new color set in fill window and make use of it to fill easily.
Hope it helps.
