• The double click on a dimension component (dimension or projection line) allows to display handles coupled with reference geometries.

• It is then possible to select a handle and slide it onto another geometry.

• Select a geometry.

• • The text of the dimension can be positioned. Its positioning defines the dimension value. (If an inclined line has been selected, the dimension can be parallel to this line, horizontal or vertical regarding the text position).

  • A second geometry can be selected to dimension the distance or the angle between the 2 geometries.

  • If a point has been selected (just highlight it and wait until it becomes yellow), the coordinate type can be chosen in the drop-down list.

  • If a line has been selected, its angle with X or Y can be dimension by clicking the adequate button.

  • If 2 lines have been selected and if there is an angle, it can be the complementary by checking the Completed to 360° option.

  • If an arc or a circle has been selected, it can be displayed as a Radius or a Diameter.

  • If 2 arcs or circles have been selected, the distance between them can be from centered or external by clicking the button.

• Style:

This cell allows the dimension style to use to be defined.

• 3D reference frame:

The frame defined in the main view is used as origin frame of measurements. In this mode, only the geometries resulting from the projection are supported.

• View frame:

• Select a corner of the view or its origin by using the corresponding icon.

• Or select manually the point on the view.

• 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: The fields Prefix / Suffix allow data to be customized.

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

• Threading/Tapping description: By checking this option, TopSolid will display the designation of the threading/tapping instead of the real value (M36 instead of 36mm, G 1/2 instead of 20.955mm).

This option allows you to add a tolerance to the dimension.

Three types of tolerance are available:

• None: no tolerance

• Manual: upper and lower deviation, display of deviation, envelop symbol.

• Normalized: tolerance hole and shaft quality, display of deviations, envelope symbol.

• Automatic: when selecting a toleranced hole, this option allows to recover the tolerance of the 3D document. The Deviations display sub-option allows to customize the display of this tolerance, the Automatic value will display it as it appears in the the 3D document.

• Dimension / Tolerance:

• Font:

Display the name and size of font used

Use the Font cell to activate the button and then modify the settings (font, style, size, effects, etc.).

• Unit format:

Displays the number of decimals of the length and angle dimensions.

Use the unit format cell to turn on the button and modify the settings (number of decimals, display zeros).

• Overlaid texts font size factor (Tolerance only):

For tolerances with overlaid texts (tolerance difference, symmetric tolerance difference, etc...), this option allows to assign a factor to the height defined in the tolerance font.

• Decoration:

Allows to select a text framing: None, underlined, framed, in an obround, under an arc or between brackets.

When the underline, framed, in an obround or under an arc mode is selected, you can define a margin between the text and the decoration.

• Color:

Allows to set the color of the dimension.

• Layer:

Allows to set the layer of the dimension.

Secondary dimension:

• Allows to define the secondary dimension: position, font and unit, tolerances, prefix/suffix, symbols framings,... A secondary dimension can use 2 different framings.

Geometry:

• Allows to modify the dimension geometry: Text and tolerance positions, dimension line definition, projection lines, ...

Extremities:

• Allows to modify dimension extremities: leader style, size, ...

When an option is modified, its button remembers changes.
