In-Depth Information
Providing a note in a drawing may be confusing. To avoid this, we use Geometric
Dimensioning and Tolerancing (GD&T) symbols to specify the tolerance values to
shape, orientation and position of a component. The following figure shows the same
example represented by using the GD&T symbols. In this figure, the vertical face to which
the tolerance frame is connected, must be within two parallel planes 0.08 apart and perpen-
dicular to the datum reference (horizontal plane).
Providing GD&T in 2D drawings is common and well known method. However, you can
provide GD&T information to 3D models as well. The DimXpert tools help you to add
GD&T information to the 3D models based on the universal standards such as ASME
