TechDraw LengthDimension

Description
The Dimension Length tool adds a linear dimension to a View. The dimension may be between the distance between two vertices, the length of one edge or the distance between 2 edges. The distance will initially be the projected distance (ie as shown on the drawing), but this may be changed to the actual 3D distance using the tool.



How to use

 * 1) Select the points or edge which define your measurement.
 * 2) Press the  button
 * 3) A dimension will be added to the View.  The dimension may be dragged to the desired position.

Options
None.

Properties

 * : Horizontal position of the dimension text relative to the View.
 * : Vertical position of the dimension text relative to the View.
 * : Allows additional text to be added to the dimension text. Dimension value will replace %.2f (or other valid printf format specifier).
 * : Length,radius,diameter, etc. Not normally manipulated by the end user.
 * : "True" - based on 3D geometry or "Projected" - based on the drawing. Not normally manipulated directly by the end user.
 * : The amount by which the piece may larger than the Dimension shown.
 * : The amount by which the piece may be smaller than the Dimension shown.
 * : "True" - ignore actual value and display FormatSpec as value. "False" - use actual value.
 * : The name of the font to use for the dimension text.
 * : Dimension text size in mm.
 * : Dimension line weight.
 * : Color for lines and text.
