Mini-CAD: Generating a normal

Lines can be generated at a user-defined angle (called the normal here for simplicity) to existing lines or edges of existing Mini-CAD system objects. Activate the "Move nodes/generate normal" icon and click the object to be edited. The nodes of the selected object are displayed. These are the two end points of a line or the defined points of a polygon.

If the line is clicked with the right mouse button between two polygon points, a dialog box opens allowing a normal to the clicked line to be generated:

Open

If the "Start", "Centre" or "End" are activated as the position in the lower group box, the length of the normal to be drawn must be given in the group box above this. Using the "Angle" input box lines can also be generated that are not classical normals at 90° to the selected line. If a negative angle value is given the line is drawn on the opposite side of the selected line.

To generate a normal of any length, activate the "With mouse" option button. A line can be generated using the mouse and can be position anywhere, even far away from the originally clicked line. The new line always remains in the extension of the originally clicked line. The length of the normal can also be defined individually by moving the mouse.
