Useful first: Turn a sketch into a solid
Cadivari exports visible solid bodies as a 3MF model in millimetres. The slicer decides layer height, supports, infill, material and printer settings. The animated pawn illustrates printing; the practice model is your block.
Try it in Cadivari
Choose the visible bodies
Open your block in CAD 3D. Show the body you want to export and hide other bodies in the object tree.
Export the solid model
Open Export in the header and choose 3MF solid model…. This command has no keyboard shortcut. Save the .model.3mf file.
Check the model in a slicer
Open the file in your slicer. Confirm millimetre units, the body name and a known dimension. A 160 mm side should still measure 160 mm.
Inspect the layer preview
Choose settings for your actual printer and material in the slicer. Slice the model and inspect the layers, including rounded edges and any cavities.
A small exercise
Export the visible block and open it in a slicer. Compare its width and height with the dimensions in Cadivari.
What you should see
The slicer receives one named solid body at the correct scale. Sketches and construction planes are absent.
Things to look out for
- 3MF export does not send a job to a printer or choose print settings.
- A failed body rebuild or an invalid mesh blocks export. Resolve the model issue before trying again.
Check your understandingWhere do you choose supports and infill
In the slicer. Cadivari exports model geometry, not a printer profile or sliced machine instructions.
