Document Properties - DimXpert

These options define whether DimXpert uses Block Tolerances, General Tolerances, or General Block Tolerances on dimensions that do not contain tolerances. Available for parts only.

To set DimXpert options:

Click Tools > Options > Document Properties > DimXpert.

Base DimXpert standard

If you select the ANSI/ASME Y14.5 or ISO standard, you can also select a release date for the standard.

When you first click Geometric Tolerance (MBD or MBD Dimension toolbar), you must then select an existing DimXpert feature or define a new DimXpert feature.

When you select a feature, the software evaluates the feature and tolerance specifications for the drafting standard you selected. In the dialog box, options are available based on the standard.

Methods

Block Tolerance A common form of tolerancing used with inch units. The tolerance is based on the given precision of each dimension, so you must specify trailing zeroes. In Tools > Options > Document Properties > Dimensions, set Trailing zeroes to Standard.
General Tolerance A common form of tolerancing used with metric units in conjunction with the ISO drawing standard. General Tolerancing is based on ISO 2768-1 Tolerances for linear and angular dimensions without individual tolerance indications. You can also use General Tolerance to customize the tolerances for your specific design requirements.
General Block Tolerance A form of tolerancing used with metric units, but may be used with inch units as well. The tolerance is typically shown in the title block or a note and applies to all untoleranced dimensions. The values for the general block tolerances are supported by custom properties.

Block tolerance

Length unit dimensions Sets up three block tolerances, each having a number of decimal places and tolerance values. DimXpert applies the Value as a symmetric plus and minus tolerance.
Angular unit dimensions Sets the tolerance value to use for all angular dimensions, including those applied to cones and countersinks, and angle dimensions created between two features. DimXpert applies the Tolerance value as a symmetric plus and minus tolerance.

General tolerance

Tolerance class Sets the part tolerance class based on ISO 2768-1 Tolerances for linear and angular dimensions without individual tolerance indications or custom tolerances that you specify.
  • Fine
  • Medium
  • Coarse
  • Very Coarse
  • Custom1. Uses tolerances that you specify in the custom general tolerance file (general tolerances.xlsx).
  • Custom2. Uses tolerances that you specify in the custom general tolerance file (general tolerances.xlsx).
For more information about Custom1 and Custom2, see Customizable General Tolerances for DimXpert.
Load Custom (Available when Custom1 or Custom2 is selected.) Loads values from the custom general tolerance file.
  • Click Load Custom when you initially select Custom1 or Custom2.
  • Later, if you make changes to the general tolerance file or change the file location, return to this dialog box and click Load Custom again.
Load custom table from (Read-only. Visible when Custom1 or Custom2 is selected.) Displays the path to the custom general tolerance file.
You set the file location in Tools > Options > System Options > File Locations and in Show folders for, select DimXpert General Tolerance File.

General Block tolerance

Length tolerance When specified, the tolerance value that applies to all linear dimensions, which includes distance, length, radial, and diameter dimensions (all non-angle dimensions).
Angle tolerance When specified, the tolerance that applies to all angle dimensions, which includes the angle between two surfaces, cone angle, and chamfer angle dimensions.
