Dimension

This command allows you to create toleranced dimensions by pressing the 3D geometry. This dimension will be visible when exporting the part if the chosen format supports 3D annotations.

Creation stages / Use:

Click the icon or select Tools > Annotations > Dimension... command from the drop-down menu.

Select the plane on which to "write" the dimension.
Select the first geometry. (Plane, Edge, Point, ...)
Select the second geometry. (Plane, Edge, Point, ...)
Validate by clicking .

To use normalized tolerances, you must first reference the TopSolid Mechanics library.
This command automatically toggles the part to the annotation stage.

You can tolerance the threadings.
Linear dimensions manage median items.

Available Options:

Text:

Prefix - Predefined Suffix: Prefixes/Suffixes can be predefined with the Tools > Options > Predefined Values > Predefined dimension Prefixes/Suffixes command.

Prefix symbol: By checking this option, several prefix symbols are available: None, M, Ø, R, SØ, SR, ...

Prefix/Suffix: by checking this option, Prefix/Suffix fields allow to customize datas.

Manual ext: Allows you to force the dimension text. A forced dimension text is highlighted in yellow.

Tolerances:

None: The dimension has no tolerance.
Normalized:
- Select the standard from the drop down list.
- Select the quality symbol.
- Select the display of the tolerance (see options below).
- Check or uncheck Envelope to add or not the Envelope symbol.
Manual:
- Select a predefined tolerance if it exists.
- Otherwise, enter the upper spread and lower spread.
- Select the display of the tolerance (see options below).
- Check or uncheck Envelope to add or not the Envelope symbol.
