Extending drawing objects to an edge
CADD allows you to extend lines to a selected drawing object. Often you need to extend lines to construct a drawing
and to fix any graphical errors. To extend lines, you need to select an edge to which the lines should extend
and then select the lines to be extended.
Dividing an object into equal parts
CADD allows you place dividing marks on a drawing object such as a line, arc, ellipse or spline. To use this
command, you need to select an object and specify how many divisions are required. This function places markers
at equal distances on the drawing object.
