I have a series of models (representing instruction steps) that I would like to
render at the same scale with LDView. I can use LDView to save snapshots from
the command line (LDView model.ldr -SaveSnapshot=model.png), but I cannot figure
out how to cause snapshots of different-sized models to be saved at the same
scale (so that individual parts are rendered at a constant size).
I thought that I might be able to use the -ModelSize or -cg options to force the
same camera perspective in each case, but this doesn't seem to do what I'd like.
Here are three example images:

Notice how as the size of the model increases, the individual 2 x 4 plates are
scaled down to fit the snapshot size. Is there a way to circumvent this effect?
Perhaps not insignificantly, I am using the 3.2 alpha version built on my Mac,
as discussed here earlier this year. I realize that ldglite or L3P could be used
instead, but I'm just curious if it is possible to accomplish this with LDView.
Thanks,
Jim

| (...) fine, as long as you set x to be big enough. With the current source code, -cg (with radius) should also work fine. Despite the fact that -cg was documented to support the radius part in LDView 3.1, it in fact didn't. I fixed that, but perhaps (...) (17 years ago, 7-Jun-07, to lugnet.cad, FTX)
