How to add Datum Feature symbol in AutoCAD

Datum feature symbol (shown in the image below) is used to specify datum geometries like plane and surface which act as a reference for measuring dimensions.

AutoCAD supports many geometric dimensioning and tolerancing symbols within its feature control frame.

And you can easily add feature control frames using Tolerance option of AutoCAD dimensions panel but unfortunately, there is no direct option of adding a datum feature symbol in AutoCAD.

So you have to improvise a little bit to add it to the AutoCAD drawing.

In this article, I will show you two simple methods of adding Datum feature symbol in AutoCAD.

let’s start with the first method which is Multileader option.

Using Multileader

To create datum feature symbol we need to create a new Multileader style. 

Type MLS on the command line and press enter.

From Multileader style manager window, click on New button then name new style as MULTI and click on continue.

Click on Leader Format tab and locate Arrowhead panel, select Datum triangle filled from Symbol drop down menu as shown in the image below.

Select Leader Structure tab then Click on Maximum leader points radio button of Constraints panel and type 2. 

Uncheck Automatically include landing radio button on Landing settings panel, see the image below.

Now go to the Content tab and click on Frame text radio button on text options panel as shown in the image below.

Click OK and then click on Close to get out of Multileader style manager window.

Select this multileader style as default and create multileader, it will look like a Datum feature symbol.
