Lines3D

Lines 3D is a simple program to display 3D objects in the form of a mesh constructed from lines and circles. The program reads simple text files (.rot), which makes it very easy to make and edit 3D models. The program is very small, requires no installation and needs no extra programs or API's to run. This makes it ideal for sharing 3D files over the internet, since all you need to do is send the program with your .rot text file.

Supports the .rot file format. The only Windows app to do so. Easy to use. Uses a text based input format. Easy to learn. Small program size. < 1MB. The program can be carried around on a memory stick. No installation required.

Anyone needing to work with 3D objects constructed from lines and circles. Anyone needing to view existing .rot files in Windows.
