Need Help Locating HSOP-8 FreeCAD Model (via GIT?)

MichaelMulligan · September 6, 2019, 8:49pm

I’m trying to get the FreeCAD model for HSOP-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.1mm so I can modify it for the HSOP-20-EP… version. [Note: the official library has footprints for -8, -20, and -36 version but 3D models only for -8 and -36 (Windoz 5.1.4-1.] I’d like a starting point more advanced than the FreeCAD blank model.

I’ve tried a variety of search strings on the GIT “File Finder”. Here are two examples:
When I try GIT (which is fairly foreign to me) I see this:

and

I’m likely doing something stupid. Any help would be appreciated.

An alternative would be to find a 3D model for the 20-pin package, but I was unsuccessful in that attempt too.

Thanks,
MMM

They are scripted.
You can find the parameters here: (changed to the correct one, Thanks Eelik)

Or rather cq_parameters_soic.py?

Shack:

Thanks. Now I have another mountain to climb - Python scripting in FreeCAD. <- That’s not a complaint.

It seems like this file gives the parameters. I need to find the code that takes the parameters and generates the models. I’ll look around now that I’m on the correct GIT continent but hints / shortcuts would be accepted.
