Samples

Generate Setup Sheets API Sample

Demonstrates generating the setup sheets for an existing toolpath.

Before running: Run from Scripts and Add-Ins. This sample may open dialogs or require interactive choices; keep Fusion in the foreground. Use a design with CAM data as required by the script. Many CAM samples switch to the MANUFACTURE workspace and may need an existing setup or manufacturing model.

Generate Toolpaths API Sample

Demonstrates generating the toolpaths in the active document.

Post Toolpaths API Sample

Demonstrates posting toolpaths in the active document using an NC program: import a post configuration from the post library, choose which setups or operations to include, set NC program and post parameters, and run NCProgram.postProcess.

Before running: Run from Scripts and Add-Ins with a design that contains at least one CAM setup with toolpaths. The script prompts for what to post (all setups, first setup, or first operation) and optionally opens the NC file when complete. It may offer to switch to the MANUFACTURE workspace.

Save and Insert File API Sample

Demonstrates creating save a new file and then inserting it into a design. To use this sample, have a design open that has been saved and run the script. It will create a new design that contains a cylinder, save it to the same folder the active design was saved to, and then insert it into the active design.
