Well, there's no thread on 3D modeling.
so now there is one.
I'll be walking through the stages of making a 3D model in a program called Sketchup.
After playing S.T.A.L.K.E.R. SoC and thoroughly enjoying the use of the Ots-14 Groza, I decided to make a 3D model of it.
First, you start with a picture in PERFECT PROFILE
THE SLIGHTEST ANGLE WILL FUCK YOUR SHIT UP
The picture I used is too large to post here, though.
You want to use it as a texture on a vertical face, and trace the outline and all the main features with the various line tools.
I kept it a little blocky, as this will eventually become a papercraft.

The magazine is straight as a placeholder, but I might leave it like that for ease of construction and just make a curved one later.
This here is one half of the Groza, in using the Push/Pull tool to extend various faces to one-half their final width. I then pasted and flipped it, to make it whole. Deletion of certain objects is then necessary, as ejection ports and fire selector switches are on only one side.

Upon making the Groza whole again, I rounded off some edges (most notably the upper handguard, receiver cover plate and pistol grip) as well as carved out the sights/carry handle.
This picture is given no edges, but it looks better with them.

After making the final adjustments and deleting unnecessary lines (most of them, that is, I always miss a few on larger models like this one) I made a few minor modifications and here is the result.

It's now ready for me to pop into a program by the name of Pepakura Designer (once I download it again, I've had to reimage since the last time I used it) so that I can make a physical model.
Here's the model, now that I've separated all the main components.

And here's the model with all of its faces laid flat.
I'll be rearranging the faces into a more scissors-friendly shape and size for a little bit. I need to head home soon, so I'll resume work as soon as I get there.
