Inserting a Dimension

A dimension provides information about an object like its length, direction, central angle, etc. at some offset distance from the object itself. It consists of a dimension line, a label, reference lines tie the end points of the object to the end points of the dimension line and optional arrows at the end of the dimension line.

Repositioning the Dimensioned Object

If you dimension an object then move that object, the dimension and its label move with the original object. You can not however, reposition a dimension relative to the object it is dimensioning.

Resizing the Dimensioned Object

If you resize a dimensioned object, the dimension lines and labels update automatically. So edit the properties of a line, trim or extend it or whatever you need to do – the dimension will update automatically.

Positioning the Dimension Label

You can position the dimension label anywhere you want. The label knows its offset from the center of the dimension line.

Modifying the Properties of All Dimensions

Each dimension gets its properties form the Dimension Settings dialog of the drawing. If you change any of the options in the Dimension Settings dialog, all the dimensions in the drawing update automatically to the new settings. If for instance, you change the color from black to gray, all the dimensions will now be gray.

Modifying the Properties of a Single Dimension

To modify any of the properties of a single dimension, right click the dimension line or label and choose Properties. TPC displays the Line or Arc dialog box if you selected the dimension line and the Text dialog if you selected the dimension label. Make the changes you want and choose OK. TPC redraws that dimension with the new properties.

TPC knows which properties you modify and holds those properties for the dimension. However, the properties you do not explicitly change are still controlled by the drawing’s Dimension Settings.

Exporting to CAD

If you use a solid arrow for the end caps and a line width greater than zero of your dimensions, TPC shortens the dimension line just enough to end the dimension line with a point.

When you export the drawing to CAD, the dimension line is not shortened, so the point of the arrow may actually be the square ends of the dimension line.
