Hairlines and Scaling

[Mark Powell]

Hi Joe

You might also consider the strategy of creating/maintaining the vectors
in an oversized stack, say 2000 x 3000 pixels in size, then exporting
cards as needed as GIF, JPG or whatever file format your program can
scale, print, or otherwise consume.  (See the export command in the
docs).  If you need a more easily viewable image in your native Rev
stack, I can imagine a scheme where you create thumbnails for viewing
within Rev.  However, not sure how you would go about having a more
easily *manipulable* (scroll-free) image in Rev.  There is no zoom-in
capability, ala Illustrator or Photoshop.

Thanks for your response, Scott.

I suppose one method for me to achieve this effect will be to print my
output at a 50% magnification. This would reduce one pixel lines to half
a pixel. Of course this means that the objects themselves will have to
be drawn at twice their size in order to produce an accurately scaled
drawing. Using one of my other programming languages I was able to do
Hairlines; whether they were 1/2 pixel width or not, I'm not sure; but
they looked narrower. FYI, I'm planning to write a program that can be
used to create shop drawings of a manufacturer's product by providing
digital input, rather than having to actually draw the items. Once I've
figured out how to do this it will reduce the time to produce these
drawings, properly label and date everything to minutes instead of the
days it now takes; even using CAD systems.

Again, thanks,

Joe Wilkins
