Mac 3D Model Split Tutorial

I have an STL file that simply needs a perfectly vertical cut so the model becomes two equal halves. I’m on macOS and, as a complete beginner, I haven’t installed any 3D software yet. What I need is an easy-to-follow, real-time walkthrough that uses a totally free (or free-tier) application—Blender, MeshLab, or anything else you trust that fits those requirements.

Here’s how I picture the session: we hop on a screen-share call, you guide me through installing the chosen program, show me exactly how to load the STL, make the clean split, and then save or export the two parts correctly. Clear explanations of each click are essential, and I’d love a few quick notes afterward so I can repeat the steps on my own.

Deliverables
• Live screen-share coaching session (≈30–60 min)
• Finished model saved/exported in the agreed format
• Short written recap of the steps taken

Patience, clear communication, and a solid grasp of Mac-friendly, no-cost 3D tools are all I’m after. If the session runs smoothly, expect prompt payment and a glowing review.
