Hi designer - often times the next step after you've constructed an object would be to bring your 3D model into a rendering program and then generate a rendering of it there with light sources set up and materials applied... That's probably the most common way that bitmap images are generated from 3D models.

If you just want a screen capture image to make a bitmap of what you see on the screen in MoI you can do that using the script that Pilou posted above. To set that up go to Options > Shortcut keys, then push the "Add" button. Inside of the new row put in whatever key you want for triggering it, and in the second column paste in the script that Pilou has above. Then when you push that key an image will be placed on the clipboard, paste it into a paint program to save it.

Also if you're working with 2D illustration programs you may want to save to PDF or AI formats for transferring your objects to a 2D drawing type format.
