Differencing two .stl files...

I've been banging my head on this most of the day...

It's been too long since I did anything in 3D editing programs.

I need to cut some text into another object.

I've used openscad to convert the text from and Inkscape .dxf file to .stl

I have MeshLab, Art of Illusion, netfab basic and Blender to work with.

AoL keeps opening another window when I try importing the second .stl in.

Netfab Basic will let me do it, but not save it unless I spring for the upgrade.

I almost had it with Blender, but then the thing kept stalling badly...

Any help with any of the above would be appreciated.

If I've overlooked doing it in Openscad, info on that would be great too.

Thanks

In AOL you can cut and paste from the new window to the old one and close the new one. PITA but it works.

In Openscad you can import both files and difference them but it is is picky about which STL files it will read.

difference() {
   import("file1.stl");
   import("file2.stl");
}

Blender will do it but be sure both files are manifolded and then wait. I have waited hours on my single core for a single complex boolean in blender.

I do this with OpenSCAD all the time!
If it can't read the STL then run it through the netfabb Cloud Service - Beta (or using netfabb Studio Basic). The cloud version is able to correct more problems than the download version (for whatever reason).

Thanks Lots guys!

I went back to AoI first as I wanted to do it in a visual editor and it reminded me of the one I had on my ST.

Looks like I have it now. Saving file now.

I'll try it some other time in OpenSCAD.
