Autocad rectangle command
It’s quicker to use the Autocad rectangle command instead of drawing 4 individual lines
A rectangle can be simply draw by invoking the rectangle command, clicking a point on screen to start the rectangle, move the cursor and click another point to define it’s opposite corner.
There are a number of ways to draw a rectangle of a specific
size. Here is a simple way:-
To draw a rectangle of size 500 by 250, start the rectangle command with REC short cut key
Click the start point of the rectangle then specify the other corner point as @500,250.
Don’t forget to use the @ sign. This will tell CAD to work out the following co-ordinates relative to your first point. If you leave this out the other point will be taken as the absolute co-ordinate 500,250 – a common error with new users.
If your version of Autocad has Dynamic mode (F12 function toggles dynamic mode on or off) the start you rectangle with a first point, move the cursor to see the rectangle forming. Note the blue input box. This is where the X (Width) value or width can be typed in. Now push the tab key to move the blue input box to the Y value (Height). Continued tab keys toggle between both values. Push enter when both values are correct to complete your rectangle.
Once you have a rectangle it is treated as a polyline. So you can use the polyline options of the fillet and chamfer commands to fillet
or chamfer all 4 corners in one operation.
An offset of a rectangle will create another rectangle either inside or outside which will depend on your "Specify side to offset" left click at the end of ther offset command.
If you only wish to offset one of it’s lines, used the explode command which will explode a rectangle back into it’s 4 individual lines.
