"Cat Brick" not working

[Boston Terrier]

Upon seeing siba's LEGO model topic in gallery, I went to port some models from LDraw and when I tested out my LEGO cat brick it is just a small square, about the size of a 2x2 brick. I exported the model as a PLY and used 3d2blb to make it a blb.

Considering that there are only 6 faces defined in the .blb file, it's likely that's because your brick is actually a box.

I don't know how 3D2BLB works, but its not a good idea to try and make a brick if you know nothing about reading/editing .blbs, you'll likely just make something that sucks / is broken. Porting models directly from LDraw into Blockland without any sort of cleanup is also something you should never do if you care for your brick's efficiency.

I did clean up, smooth it, etc

Good, just long as you removed unnecessary detail and lowered the overall face count to an acceptable standard. (LDraw models are very high-poly).
