How to add STL and OBJ 3D channel models in PrintUP (from this page)

The live page body is short; the on-page "Video Transcript" block is the step source. Raw auto-caption is not copied in full; no transcript invented. Cleaned steps from that live block:

  1. This Part 3 is Add 3d Models / adding STL and OBJ 3D channel models in PrintUP, named as having more capabilities than the first two methods, and requiring more 3D modelling knowledge.
  2. The live block recaps the first two methods already covered: File Input Graphics, then Model / Create word model.
  3. If you already know 3D modelling and have your own programme, export models as STL or OBJ (named as the common 3D-printing formats) and add them straight into the PrintUP project.
  4. Open the model list on the left (click Model list if it is not showing). Click Add; a navigation bar pops up.
  5. Supported formats named on the live block: OBJ and STL. Leave all supported formats, select the file, click Open.
  6. The live block then imports an OBJ and an STL. One model has errors and the other does not (visible difference, including red). Recap from the live closer: softwaretraining.co.za search (top right) and the on-site request-a-training-video form if a video is missing. Avia next on this URL is a different page at https://softwaretraining.co.za/channel-letter-customize-3d-model (pretty slug printed; not invented; not fetched).
