This tutorial from CAD Skills focuses on the specific task in the title. STEP, DXF, URDF and G-code target different manufacturing or robotic processes; after the Agent generates the file, it must check the units, coordinates, closed contours and processing boundaries with an independent viewer.
Below is a demonstration using a test environment and revocable data. When accounts, keys, machine control, investments or emergency communications are involved, manual confirmation must be done.
The four output formats are selected according to the purpose.
This section only deals with “the four output formats are selected according to the purpose”. Save the current state first and then run the minimal test. Do not change multiple conditions at the same time.

For CAD Skills, this boundary must be combined when judging the results: STEP, DXF, URDF and G-code are oriented to different manufacturing or robotic processes; after the Agent generates the file, it must use an independent viewer to check the units, coordinates, closed contours and processing boundaries.
If the results are not repeatable, record the version, input, and logs, then narrow the scope of the test.
Installing Skill and installing CAD kernel are two different things
It is recommended to execute in the following order:
- Check the actual version and source.
- Use a test account, test directory, or test device.
- Perform an undoable action.
- Save the output, exit code, or screenshot.
- Revert the changes and re-verify.

The completion standard is “Installing Skill and installing CAD kernel are two different things” and getting verifiable results, rather than the command just not reporting an error.
The first STEP only makes blocks with holes

Final Check of CAD Skills
- The versions and sources used are documented.
- Test input and formal data have been isolated.
- Commands, configurations and actual output can correspond.
- The failed path was actively tested at least once.
- Keys, accounts and private data do not enter Git or logs.
- There are clear actions for upgrading, stopping and resuming.
If you still can’t explain how the results are produced, continue to keep the CAD Skills in a test environment without extending permissions or replacing existing stable processes.
