Orthogonal drawing |
Scroll |
The orthogonal drawing mode is used to quickly create objects or their parts orthogonal to the axes of the current coordinate system.
The Orthogonal Drawing 
command is used to enable the orthogonal drawing mode.
This command button is also an indicator of the orthogonal drawing mode: the pressed button means that orthogonal drawing is enabled; the released button means that it is disabled.
If, in the process of building an object, it is required to temporarily disable (or enable) this mode, press and hold the key and hold the <Shift> key.
The orthogonal mode is convenient when, for example, drawing horizontal or vertical segments and straight lines, or when creating designations for stepped cuts. An example of operation using the orthogonal drawing mode is given below.
Example of operation in the orthogonal drawing mode
To practice working in the orthogonal drawing mode, do the following.
1.Create a new graphic document (a drawing or a fragment). Make sure the orthogonal drawing mode is disabled. If necessary, disable it.
2.Invoke the Drawing – Geometry – Line – Line command and point to the first dot of the line with the cursor.
3.Move the cursor across the field of the document and watch the line phantom.
The final point of the line coincides with the cursor, it can be fixed in any place of the drawing by left-clicking it.
4.Enable the orthogonal drawing mode.
5.Move the cursor.
Now the phantom of line is strictly horizontal or vertical depending on the direction, closer to which the cursor is placed.
6.Fix the final point of line.
7.Set the starting point of other line.
8.Move the cursor across the field of the drawing. Make sure the phantom of line is built orthogonally to the axes of the current coordinate system.
9.Press and hold the <Shift> key and keep moving the cursor.
The orthogonal mode has been disabled, and the segment is built in the normal mode, following the cursor movement.
10.Release the <Shift>key. Make sure the system has switched to the orthogonal mode again.
11.Create a slanted local coordinate system.
12.Enter several lines by pointing their starting and final points by marking with the cursor. Make sure that segments are created orthogonally to the axes of coordinates of the current LCS.
