Form Checks

Geometry relationships are designed to be computed quickly and repeatedly. For this reason, form checks do not use the full GD&T mathematical evaluation methods. Instead, they use a simplified computation based on the RMS fit object. Details are as follows:

These form results typically overestimate the form value by a small amount as compared to a full GD&T check result. A check that is true to the ASME or ISO specification can be added by linking a GD&T check to an existing GR-Feature.
