On the Job Preferences dialog, you can define a group dimension line, which lets you create dimension lines for several structure elements included in a structure plan or view.
When you modify certain elements (such as openings) or change their overall dimensions, the changes are instantly reflected in the relevant dimension chains.
The Definition tab

Use the options on this tab to define the group dimension lines of objects of a building:
- Total dimension - select this to add the total dimension of a structure element to the dimension lines
- Characteristic points of a building - select this to add dimensions between characteristic points of objects (for example, indentation in a wall or beginning/end of a wall)
- Adjoining elements - select this to automatically dimension elements that adjoin the main element. Use this option primarily with elements that adjoin walls:
o Columns
o Walls
o Beams
o Columns included in the wall
- Opening dimension - to axis - select this to add dimensions between characteristic points of an object and opening axes. A description of a dimension line depends on the parameters specified on the Openings tab
- Opening dimension - to face - select this to add dimensions between characteristic points of an object and faces (edges) of openings. A description of a dimension line depends on the parameters specified on the Openings tab.
The Openings tab
Use the options on this tab to determine a method of describing a dimension line for openings (opening dimension - to face). The description of an opening dimension line may consist of:
- Opening width
- Opening height
- Sill height (only for window openings)
The description of an opening dimension line may be placed in 1 line (above the dimension line) or in 2 lines (above and below the dimension line). To determine the method of describing a dimension line:
- Select the appropriate dimension components
- Specify a location of the description (the upper edit field will position the description above the dimension line, whereas the lower one will position the description below the line)
- Click the arrow
to update the edit fields with the selected dimension component data.
