Can you do draft analysis in CATIA?

Yes, draft analysis can be performed in CATIA to analyze whether a part model created in CAD is manufacturable based on the draft condition applied. This analysis is particularly useful for molded plastic objects, as it helps to ensure that the objects can be successfully removed from the molds.

The draft analysis tool is available within the, insert > analysis > draft analysis workbench. It provides a color-coded representation of draft angles, with green surfaces showing correct angles, red indicating angles too close to the draft angle, and blue highlighting unacceptable angles.

The ideal draft angle for plastic components is typically around 3 degrees, but this may vary according to functional requirements.

The draft analysis command enables users to detect if the part they drafted will be easily removed, and it is particularly important for ensuring manufacturability and easy ejection of components from molds or dies.
