Описание
The TechDraw HorizontalExtentDimension tool adds a linear dimension to a View. The dimension extends from the left most point on the selected objects to the right most point.
Horizontal and vertical extent dimensions of a B-spline
Usage
- Select a View or a collection of Edges in a View.
- There are several ways to invoke the tool:
- Press the
Insert Horizontal Extent Dimension button. - Select the TechDraw → Dimensions → Insert Horizontal Extent Dimension option from the menu.
- Press the
- A dimension is added to the View.
- The dimension may be dragged to the desired position.
- If needed, add tolerances as described on this page.
Change properties
To change the properties of a dimension object either double-click it in the drawing or in the Tree view. This will open the Dimension dialog.
Ограничения
Dimension objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension.

Программирование

The Horizontal Extent Dimension tool can be used in macros and from the Python console by using the following functions:
selection = ['Edge1', 'Edge2'] # or [] for all
TechDraw.makeExtentDim(view1, selection, 0) # view1 is a DrawViewPart; 0 for horizontal
App.ActiveDocument.DimExtent.Y = -60 # offset dimension line from dimensioned edges in Y direction
App.ActiveDocument.DimExtent.X = 10 # offset dimension text along dimension line in X direction
App.ActiveDocument.DimExtent.FormatSpec = '%.0f' # Dimension format
TechDraw.makeExtentDim(view1, selection, 1) # view1 is a DrawViewPart; 1 for vertical
App.ActiveDocument.DimExtent001.X = -130 # offset dimension line from dimensioned edges in X direction
App.ActiveDocument.DimExtent001.Y = 10 # offset dimension text along dimension line in Y direction
App.ActiveDocument.DimExtent001.FormatSpec = '%.0f'
# Note the dimension names are 'DimExtent', 'DimExtent001' etc in the order created.
