Drawing lines, circles and arc
Isometric lines and non-isometric lines can be drawn using line or polyline command
Isometric circle can be drawn using ellipse command
Draw ellipse > isocircle
Isometric quarter circle and semi circle can be drawn using ellipse arc command
Draw ellipse arc > isocircle

Use quick leader for isocircle
Aligned dimension
Quick leader
08 AutoCAD 3
To make dimension aligned with isometric axes, follow few steps as:
- Type DIMEDIT
- Specify the obliquing angle
For example, using the object above, for clockwise alignment such
as 90, type 30 for the angle, whereas for 100, type -30 for the angle
since anti-clockwise alignment.

Dimensioning for Isocircle
Select the circle, then extend the leader line to appropriate
direction, click, then make short extension in horizontal direction,
click,then type corresponding value (example: R20)
for the dimension.

Other useful tips
Use COPY command with polar relative coordinate system or OSNAP.
Do not use OFFSET command.
Set up LAYER before drawing.
Use construction line as a guide (recommended to use different colour)
