Frequently Asked Questions (FAQs)

---

1. How do I batch import point coordinates into ZWCAD?

Commonly asked by users working on survey-to-CAD or importing automotive points.
👉 Answer: Use the built-in coordinate import tool or dedicated batch import command in ZWCAD, mapping your CSV or coordinate file into the drawing. ([zwsoft.com][1])

2. Why does ZWCAD show “Unknown Command” when I type a familiar CAD instruction?

This often occurs when switching from AutoCAD workflows.
👉 Answer: An unknown command error typically means that the command isn’t available in your workspace or version. Ensure you’re using the correct edition and that your alias file includes the command. ([confluence.zwcad.com][2])

3. How can blocks be renamed or modified (single and batch) in ZWCAD?

Block editing is essential in automotive design for reusing templates and assemblies.
👉 Answer: ZWCAD supports block editing directly. You can rename blocks via the block editor or modify block attributes in batch mode. ([zwsoft.com][1])

4. Why do copied blocks change appearance or attributes when pasted into other drawings?

This is a common CAD interoperability issue.
👉 Answer: This occurs due to mismatched layers or missing block definitions. Ensure reference layers and styles are consistent before pasting blocks. ([zwsoft.com][1])

5. How to enable auto-save and recover a drawing after a crash?

Data safety is a top concern in automotive design workflows.
👉 Answer: Enable auto-save in settings; if ZWCAD crashes, open the auto-save file from the temporary folder to recover recent changes. ([zwsoft.com][3])
