Upon calling the dimension creation command, one can click near any construction or graphic line. The
line will be highlighted. Alternatively, point the mouse at a line and type . Also, one can select a node
(the key ) or a circle (the key ).
Depending on what was selected at this step, different options are provided for further construction.
Dimensions between Two Straight Lines or between Line and Node
If the first selected element was a line, proceed with defining the second dimension
reference element.
To construct a linear dimension, the second element can be another line parallel to
the first one, or a node. To construct an angular dimension, select another line
positioned at an angle to the first line.
Upon drawing dimension between two lines, the system itself finds the nearest nodes lying on these lines and
ties the origins of the extension lines to them. While doing it, however, there is always a possibility to
reassign the nodes to which the dimension will be tied.
The following set of icons will be available in the automenu:
Select Line (a construction line to tie the dimension to)
Select Node (to tie the dimension to)
Cancel selection
Obviously, the second dimension reference element can be selected using the common T-FLEX technique.
One can click or type , while pointing the mouse at a construction line. One can select a node using
the option . This creates a dimension between the line and the node.
Once the second dimension reference element was selected,
regardless of the selection technique, a dimension will start
rubberbanding on the screen following the pointer
movement. The start point and the end point of the
dimension line will be marked by numbers: “1” – the start
point of the dimension line, “2” – the end point of the
dimension line.
The new options that appear in the automenu, hint of further possible actions. This relates to either the linear
or the angular dimension (in the case when the two selected lines intersect).
The available options after specifying the dimension references are:
Set Dimension parameters
Copy Properties from Existing Element
Change leader line jog orientation
Change Dimension Orientation (for angular dimension)
Place Dimension in absolute coordinates
