Tolerance |
Some operations are not able to produce an exact result, and in that case an approximation is made.
For instance, when uniting two cylindrical shapes, the intersection curve between the cylindrical faces is an approximation and does not exactly coincide with the faces.
This command allows you to modify the modeling tolerance of some operations. To change this tolerance for the futures operations of this document, the modeling tolerance is informed in the document options.
Creation stages / Use:
Select the Tolerance... contextual command from the operation
Enter the value of the Linear tolerance (0.01mm by default) which sets the maximum acceptable error in distance between a point of approximation and the exact corresponding point on the object.
Enter the value of the Angular tolerance (0.05° by default) sets the maximum acceptable error in orientation between normal in a point of approximation and in the exact corresponding point on the object.
Validate.

The finer the tolerance, the better the modeling quality, but the larger the memory consumption and the worse the overall performance. You should therefore use the coarsest tolerance possible that is compatible with the modeling quality requirements (for instance, if a part will be manufactured with a tolerance of one tenth of millimeter, there is no point modeling it with a linear tolerance of less than one hundredth of millimeter). |
