Hi Sam!

Sure! I believe MOI 3D would be a very good choice for that! ( I was able to recreate your box/container geometry in MOI in matter of minutes! ( take a look at the attached file)

Note_1:In MOI 3D every thing is built around speed :-) So, for your box if you make top part and side part you can quickly mirror top/and side part to get bottom and other side part! By assembling them you are able to get your back part just by drawing a box and extrude it ( until now you would have a simple extruded box with height of your desired final box and width of it would be equal to width of your desired final box needless to say it thickness is equal to thickness of your plexi sheet you want to cut your box out of! ) in next step you put this raw box on the place your back part would rest; then you can perform boolean subtract operation and subtract top+bottom+sides from your raw box! and there it is! your back part! ( in a matter of seconds well maybe few minutes)

Note_2: if you assign a short key to below script you would be able to select a face and quickly extract outline of the selected face! ( that would help you to quickly get the outline of your back part for your laser cutting project!) MOI is able to save files in DXF format and to my knowledge most laser cutting machines can read that format! :-)

script: /* Select edges v1.4 */ var gd=moi.geometryDatabase, so=gd.getSelectedObjects(); function ss(o,v){o.setProperty("selected",v)} function sl(o){ for ( var i=0; i<o.length; ++i ) o.item(i).getEdges().invertProperty("selected");} gd.selectLoop(); sl(so.getFaces()); sl(so.getSolids()); sl(so.getOpenBReps()); sl(so.getSingleFaceBReps()); ss(so.getBReps(),0); ss(so.getFaces(),0);

Note_3: Recreated box is based upon the image you sent! therefor the holes are missing! The gaps that would be created due to laser cutting in not calculated! and my estimation is that the dimensions of your box are approximately as follow: 98 mm by 120 mm by 30 mm (Or 3.85 inches by 4.72 inches by 1.18 inches)

You say "Outlines" from a selection of faces
seems it's more Outlines of "each faces" ?
Am I right ?

Yes! You are right :-)

But for sam's case it works! ( I mean if he generates the back part using boolean subtracts and then selects just of face he would be able to extract outlines for his laser cutting project ) :-)



1- shows the object generated using boolean (subtract)
2- if you select the face shown and then using the script you are able to select edges connected to that face
3-Outline which is needed for Sam's laser cutting project :-)

Sam, I use Moi every day to create models for 3D printing using SLA and LCD technologies. I also use it for laser cutting, sometimes using the 2D base of a 3D model. It works FLAWLESSLY in this capacity. It is "engineering grade" 3D design, not just a toy for doodling.

Spend the *tiny* sum that Moi costs. I also use Inventor and Solidworks, and their price tag is jaw dropping, but their workflow is not. Moi has an amazing price point and an excellent intuitive workflow.

Good day.
After trying allot of other 3d softwares..sketchup,Rhino, blender etc I bought Moi since it was very easy to learn and getting thing done quickly.

I use Moi3d with Prusaslicer for all my 3d printing needs, also for 2d drawings and just for about anything I want to build and design.
Right now I have a 4x8' cnc router and rotary axis on its way...For this I will be using Moi3d, VcarvePro and maybe 3dcoat for more artistic stuff.
