Topic: Help! need to split a model!

hello all,
A friend of mine designed a model that he would like to print but he modeled both pieces at the same time and I for the life of me cannot figure out how to split them into two separate pieces!
If someone would be so kind as to make the two parts into two separate .stl files it would be greatly appreciated!

Thanks in advance!
Brandon

I've used openscad for this - import the STL then intersect it with a shape that cuts off the bit you want and save the new stl.

Re: Help! need to split a model!

I'd do it but I'm not near the desktop...
Trust me when I say it's worth learning how to do it yourself tongue

Blenders "Boolean" modifier is extremely useful for this, just youtube it for tutes.

This is a crowd funding thing that I'm running: http://www.gofundme.com/bvi140 It's for pretty selfish reasons tongue

Re: Help! need to split a model!

Hi! I might be late in replying to the thread, but for the records I wrote a small python script some time ago for exactly this purpose:

Enjoy!

Re: Help! need to split a model!

Why not just use latest version of Repetier?  There is a split object icon on main object placement screen.  Click it and object will be split in to two objects.  Select one and save as stand alone object.  Repeat and select the remaining object and save.

Download and install NetFabb Basic.  Load the STL then right click on the model and select Move.  Click on Move to Origin button.

This will move the model to the build surface.  Now right click again, and select, Extras/Repair Part.  This puts netFabb in Repair/Edit mode.   Click the Shell Select icon on the top menu, then click one of the object.

The selected object will turn green.  Right click on it, and click Extract Selected Triangles as Part. Tis will create a new sub-part on the parts menu.  Repeat the process for the remaining parts.

Then right click each part and select Export Part / As STL.

That's it.

Here is how you can both split a model into pieces and also how to separate by parts: 3dprintingninja.blogspot.com/2014/12/how-to-split-separate-model-in-blender.html
