This presentation gives some hints for starting the use of ZWCAD for plane drawings.
Only very essential elements are pointed out. Practice is necessary.
We first explain setting up, some switches and pull down menus.

Most times we want to draw an object starting from the end of a given object, mid-point of a line, from or to the intersection of two objects, tangent to a curve, or normal to a line. This is achieved by what is called Snapping to Object or Object Snap for short.

Turns object snap on or off
Turns ORTHO on or off
Turns grid on or off
Turns SNAP (to grid points) on or off
Some useful switches near the bottom
These can be turned off and on even in the middle of a command depending upon the requirements

Layers:AutoCAD permits drawing in overlapping layers. These layers can be of different colours, each colour of different line thickness, and a layer could be viewed or not viewed.
This is invoked also from the pull-down menu FORMAT>LAYERMore convenient there

Press this button to set up a new layer.
Use this button to set up a different colour for this layer
This controls the visibility of the layer. Press this button to change the Sun into a snowflake. The layer is invisible if it is a snow flake.

EXAMPLE: Draw a regular pentagon of side 40 mm. Offset out all lines by 10 mm and inscribe a circle. Also Dimension it.
1. Turn ON GRID, SNAP, OSNAP2. Select ENDPOINT, MIDPOINT, INTERSECTION, TANGENT & CENTRE3. Select LINE in DRAW toolbar, go to a point of grid, click, go horizontally 4 grid points (40 mm), click.4. At command line To Point: type @40<72 [@ for relative distance, < for angle measure, 72 being the angle through which a line turns in a pentagon.
