To Check for Interference
1. After you have defined a move, click Define Step > Interference.
2. Click Static Part and select the part to check against. Moving member(s) are checked for interference with the static part and the results are reported. If an interference is detected, it is indicated by highlighting the curves in yellow.
3. Click Static Part again to perform the interference check with respect to another static part, or click Done/Return on the MOLD INTER menu.
If interference is detected, you can delete the move and try another way of mold opening. Sometimes, you may have to redefine your mold components.
