2 CAD FUNCTIONS
As described earlier, CAD functions can be accessed either from the menu or via
Toolbar buttons. The Toolbar operates on a two level system – Column 1 is the
main function (Lines, Arcs, etc.), Column 2 is the sub function of the selected main
function. The majority of functions remain activated until you choose another
function. The current function and the prompts are shown in the status bar
Whenever a point is asked for it is displayed in the bottom right corner of the status
bar. Points can be defined by clicking in the drawing area or by choosing a Snap
Mode function.
On the following pages each of the CAD functions along with the icons are
described.
2.1 Lines
Line 2 Points- Prompts for Point 1 and Point 2. If the layer is
construction the line will be projected to the bounds.
Line to Point- Set first snap point and second line will automatically ask
for only the end point of the line.
Parallel Element- Distance- Line parallel to a line at a given distance.
Touch the line on the required side and then give the distance.
Parallel Element – Point- Line parallel to a line through a point. Select
the line segment and then define distance via snap function and exact line will
be duplicated parallel from the distance entered.
Double Parallel Lines- Two lines parallel to a given line. Touch the line
and input the distance
Common Tangents- Common tangent to two circles. There are 4 possible
tangents. Depending on where the circles are touched determines which tangent
is drawn. To create an Obround draw two circles and 2 Common tangents and
then use the Cut 2 points function to remove parts of the circles.
