Hi Michael,
It turns out that it would be handy to be able to set page margins to 0 when exporting SVG/PDF/AI. This would make it easy to compose a scene in MoI in page space. It would also be helpful for illustrating a combination of transparent and opaque parts and for making changes to a perspective illustration that's already fairly far along in vector graphics, because then just the changes can be exported from MoI on registration with the original export. In other words, being able to set page margins to 0 will make it easy to composite multiple renderings from MoI by having the renderings be registered to page space.
Say I want show a transparent disk on top of an opaque ring:
I need to render the disk with hidden lines generated, but not generate hidden lines for the opaque ring. And I need an Outline that goes around everything. If I try exporting an SVG of the glass with hidden line generation on and then another of both glass and ring with only visible lines:
And then combine the resulting SVGs I get garbage that needs to be aligned by scaling and moving:
But, if I add a bounding rectangle to the scene that has the same aspect ratio as the target page size less 2*12pt in height and less 2*18pt in width then combining multiple renderings is just copy-paste:
Here's what the bounding rectangle setup looks like in MoI:

So, while I can do this now by using a rectangle with an aspect ratio exactly 24x36 pt smaller than the target illustration size, it's a little awkward to have to do the arithmetic remembering which direction is 24 pt and which is 36, and it's kind of hard to judge a composition relative to a rectangle that's not quite the same size as the finished illustration.
