Is this a free program that will also work on Mac?

how do you export a file like the one shown with the dimensions? I'm signed up with Onshape but am a total newbie and not sure how to use it yet

I noticed that the drawing feature works just fine when I create a part using Onshape but my imported STL file just isn't working. I've tried DXF and other formats and it doesn't;t want to budge

I'm confident that I used Tinkercad to create the image in the post. That would mean that I exported it to a file format compatible to Onshape. It's been so long ago, I don't have a clear answer, although DXF is a poor choice. Look for .STP or .step or similar.

What does your milling machine take for input?  E.g. convert the STL to an OBJ file and that may be all you need.

The normal process is to start with a CAD file, and then generate a dimension drawing for manual machining, or an STL file.

@CarlWitthoft yeah that’s pretty much what I did a and was manually adding dimensions to a screenshot...I was thinking there must be an easier way and I think the guy who suggested Onshape takes the cake with his suggestion.

I've had good results with using the free web-based program known as [Onshape](https://www.onshape.com/) which allows you to import/create 3D models. One of the features built into Onshape is a drawing tab. You can select the views desired or use a standard layout, as well as add dimensions to the individual drawing views.

[![Onshape image example](https://i.sstatic.net/EnQlH.png "Onshape image example")](https://i.sstatic.net/EnQlH.png "Onshape image example")

This image above was of a model created in and exported from Tinkercad. No dimensions have been added in this example, but it's available as part of the software. Being browser based, the program will work for any platform.

In order to make this answer more accurate, I attempted to duplicate the results shown in the drawing.

I've discovered that I used Fusion 360 to import the STL. The next step involved turning off history feature, then converting the STL to BREP. Once in BREP form, the no-longer-STL file can be exported as .step, which is accepted by Onshape.

Fusion 360 is a free-to-hobbyists program, but does not run in a browser. There may be other programs which will convert STL to .step and there may even be a browser converter-specific site to accomplish this.

I recognize that this is a convoluted solution, but it's not particularly burdensome, overall.
