If CAM Assist read a threaded hole wrongly, or couldn't identify the thread (Unknown thread), pick the correct one from the thread catalog. CAM Assist uses it to plan tapping or thread milling.
Before you start
- In the Feature planning stage, click Open details on the hole group card, then click the thread on the left or in the diagram. See Review and edit hole groups in Feature planning.
- If CAM Assist found likely threads for the bore, they're listed under Suggested for this bore. Click one to use it without searching.
Pick a thread
- Click the Thread field. The thread picker opens.
- Type a designation or size, for example
M8x1.25or1/4-20. The list narrows as you type. Currently set shows the thread the hole has now. - Optional: click Refine and choose standards under Prefer these standards (Metric, UTS, BSW, BSPP, BSPT, NPT). Matching threads move to the top; the rest stay listed under Outside your refinements.
- Click the thread, or highlight it with the arrow keys and press Enter.
- Click Done to keep the change.
Each row shows the Standard, Major ⌀, Pitch and Tap drill. If the list says "n more — keep typing to narrow them down", add more of the designation.
No thread in the catalog matches that. means nothing matches your search. Check the designation or try the major diameter.
You can also change the thread straight from the card: click the thread line in the card's callout. The picker there works the same way.
Check the thread's dimensions
Click the info button next to the Thread field (What this thread specifies). The Thread window shows the thread's profile with its Major diameter, Pitch diameter, Minor diameter, Pitch and Tap drill. Where the thread's default tolerance class publishes limits, the diameters are shown as ranges.
Then set the Thread depth and Threading process. See Hole element settings.
