In this article, I will tell you about making isometric dimension and text in AutoCAD drawing. For explaining this feature I will use a simple isometric cube as shown in the image below. If you want to learn about making isometric geometries in AutoCAD then follow the related article.
Making Isometric Dimensions:
Make aligned dimensions A, B and C on the geometry as shown in drawing A above using DIMALIGNED command.
Now type DIMEDIT on the command line and press enter, select oblique from the command line as shown in the image below.
Now click on dimension marked A from drawing shown above and press enter. 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 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 this after using DIMEDIT on all three dimensions.
Making Isometric Dimension Text:
The dimensions now look correct but when you look closely at dimension text they are still not properly aligned as per drawing. You need to make changes to dimension text also in order 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 case.
From the command line, select 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 in DIMTEDIT command.
Making Isometric Text:
To write text on the isometric cube type TEXT on the command line and press Enter. Now click on the face of cube towards dimension C and enter a text height value and rotation angle of 30 degrees in the command line prompts.
Type any text and press enter twice to exit the TEXT command, I am using “Text” as the sample text on the isometric cube.
Repeat the process of writing text on the face of cube towards dimension B as well, but in this case change angle of text to -30 degrees keeping all other parameters unchanged.
Now select text on the face of dimension C then right click and select properties from the contextual menu. From the Text panel of properties palette change value of Obliquing to 30.
Repeat the process for text on cube facing dimension B but in this case change obliquing value to -30. The final drawing with isometric dimension and text will look like the image shown below.
