Is there a way to draw LEGO figures using Blender? I have some basic experience in Blender. Is there any way to insert pre-drawn LEGO pieces into Blender?
First note that this question is a possible duplicate of Do any programs exist that allow you to build your own LEGO manuals?  With that, here is the answer: 


(optional) Create a model in LEGO digital designer or LDraw and export it as a LDraw (*.ldr) file. 
Install LeoCAD, and either open the model that you made in LDD/LDraw (recommended) or create your model directly in LeoCAD. 
Export your model in LeoCAD as a 3D studio (*.3ds) file and import that in Bender.


I learned this technique from this very site less than a week ago and have already tried it out.  So far, it works great and has given me loads of ideas.

Edit: The Linux version of LeoCAD currently does not export to the *.3ds file format, so you can not set up a pipeline that way; I know this from experience.
