Linear Dimensions (2-D)

Linear dimensions are created by identifying the start point and end point of a line and a third point with respect to the point for position determination of the dimension line and dimension figure. With variable dimensioning, a line can also be identified for the 1st and 2nd point. This then gives rise to angular dimensioning.

There are various ways in which you can define the position of the dimension line by entering the third point:

Placing any point
If you specify any point for the third point without point option, the dimension line will be laid exactly through this point.
Default dimensioning L
If you enter point option L (last point) instead of the third point, the default dimensioning is automatically carried out. The distance of the dimension line from the line element to be dimensioned or from the two points is predefined in BEMPAR.DAT.
Point option B
If you use point option B instead of specifying the third point, the dimension line is aligned exactly to an already existing dimensioning unit. An existing dimensioning unit is selected and the midpoint of the corresponding dimension line adopted as the point.
