In Vectorworks, if you wanted to create a square which has another square cut out of the middle, leaving a 5mm wide "border", it's quite easy. The way I do it is:
Make a square (e.g. 100mm x 100mm)
Duplicate the square and scale by 0.9
Use the clip function to get the desired result
The steps above are shown in the following images:
That's easy enough. You can then extrude or do whatever you need.
In this case, I've been provided with a polyline. Let's say it looks like the following image:
If I wanted to do the exact same process as above, to essentially make a duplicate of the shape with the lines "pulled in" or by 5mm each, how would I go around doing it?
In Photoshop, they have a tool that allows you to "Contract" a selection, as per the following images:
How would I go around doing this in Vectorworks? What methods/tools should I be looking at? The polyline I need to apply this to is quite specific, so it's quite hard to redraw.
Any tips would be greatly appreciated.
