To help explain this feature we will use a simple isometric cube as shown in the image below.
Making Isometric Dimensions:
Place aligned dimensions A, B and C on the geometry as shown in drawing A above using the DIMALIGNED command. Now type DIMEDIT on the command line and press enter, select oblique from the command line as shown in the image below.
Next click on the dimension marked A from the drawing shown above and press enter. The command line will prompt you to select an angle to align this dimension. Type 30 and press enter again. Your dimension will now align with the geometry to make it look like an isometric dimension.
For dimensions B and C you can use the same method with the oblique angle of 30 and -30 respectively. Your final drawing will look like cube B above after using DIMEDIT on all three dimensions.
Making Isometric Dimension Text:
The dimension lines now look correct, but the dimension text isn’t properly aligned as per drawing. You also need to make changes to the dimension text to make it look normal.
Type DIMTEDIT on the command line and press enter, then click on the dimension which you want to edit, I am selecting dimension C for this example.
From the command line, select the Angle option and type an angle of 30 degrees then press enter. The dimension text will now align with the dimension line. For dimensions A and B use an angle of 30 and -30 degrees respectively using the DIMTEDIT command.
In my next blog, we will look at placing isometric text. I hope these tips prove useful when using the isometric drafting tool.
