yeah, i made a test array of 200,000 line segments and Moi was crawling. i know that joining a big network, the program will have to decide which ends to connect to which nieghbors. But i figure that might reduce the total # of objects by a significant count, no matter how they get joined up. So in turn might speed things up (?)... Just a thought...

Hi knightxor, I just made the converter program, you can download it from here:
http://moi3d.com/download/Obj23dmWireframe.zip

Unzip it to some folder, and then you can run the Obj23dmWireframe.exe program.

It will prompt you for the name of an OBJ file, and then the name of a 3DM file - it will read all the polygon data from the OBJ file and convert the edges of polygons into line segments and save those line segments to the 3DM file. You can then load that 3DM file into MoI.

So this gives a method to bring the wireframe outline of polygon mesh objects into MoI to use as construction guides.

I hope this helps, and please let me know if you run into any problems.

Hi Jonah, I haven't really worked on this particular area for dealing with a high volume of separate individual simple entities.

I took a look over some stuff and it looks like I can do some pretty easy optimizations to tune this up a notch, an initial test looks like a 2x speed increase, possibly more at higher volumes.

I'll dig into it a bit more tomorrow.
