Isometric Dimensioning

How to put dimension in an isometric object from a 2D drawing? That is the question I received from one of my colleagues sometimes ago, what my colleagues trying to say is, he’s basically want to put a dimension aligned to the isometric object. At first, I thought it is not possible to put a dimension on a isometric object within a 2d drawing, because prior to that question, I have not done such a thing. Good thing one of our senior colleagues had encounter such a predicament before, and so he teach us how to do it.

Dimensioning an Isometric drawing is easily to forget, specially if you ‘re  not using it frequently because it is not a single command, it is a series of commands composed specifically to do one task. That’s why it is best that I should blog this tutorials.

So here it is.

First, after you have created your isometric object put a dimension by using the command, DIMALIGNED by typing it in the command prompt or click the dimaligned icon.

Using Dimension Space

Dimension presentation is vital in a drawing, a drawing plans cannot be use if the dimension is not readable. Thats why it is important for us AutoCAD Drafters and Architects that we assure that, the dimensions are shown in a nice and in a readable way. But sometimes, in an unavoidable situation like rushing up yourself to finish your drawing and eventually making it to submission day. This is the time when your drawing presentation might suffer, specially the dimension presentation.

Good thing, AutoCAD has this routine, that can automatically adjust existing parallel linear and angular dimension in a drawing, so they are equally spaced or aligned at the dimension line with each other.

This routine called, the Dimension Space, or DIMSPACE, you can find this routine at the Dimension Pulldown menu, Dimension Space, you can also find it at the dimension toolbar (fig.1). Alternatively, at the command prompt, type DIMSPACE, then ENTER, then select the dimensions you want to adjust. The dimension that to be selected must be linear or angular, of the same type (rotated or aligned), parallel or concentric to one another, and on the extension line of each other. See the example below (fig.2 and fig.3).
