AutoCAD: Dimreassociate / Reassociate

Written by Cindra Drowne-Walsh

Not a highly used command but good to know to keep your drawings technically on track with functions and features that AutoCAD offers. 

Reassociate / Dimreassociate is the command that connects (Associate) or disconnects (Disassociate) dimensions to the geometry. One of the greatest features that AutoCAD offers is the association between Dimensions and Geometry. With this association when you update the geometry the dimensions update automatically. So there is no reason to modify a Dimension to “fudge” in a number, modify the geometry and the Dimension will updates.

Where to locate this Command:

From the Command Line:

Command: DIMREASSOCIATE ↵ (Enter)

Select dimensions to reassociate

Select objects or [Disassociated]: (select the dimension to be associated) 1 found

Select objects or [Disassociated]: ↵ (Enter)

Specify first extension line origin or [Select object] <next>: (select where the First extension line placement is wanted)

Specify second extension line origin <next>: (select where the Second extension line placement is wanted)

Command: (the command completes itself so no Enter is require and you are ready to start with the next command.)

*Anything in the color RED is my added input you will not see this on the command line.

From the Ribbon:

Associate tab – Dimension Panel – Associate Button.

Ribbon 2

The Command line prompts are the same as if they were Typed in as the above example.

Below is a quick example of how the Reassociate / Dimreassociate command works:

*note this command also offers the revers of Associate [Disassociate] if you want to take the association of the dimension to the geometry off.

AutoCAD: Area command quicker than bringing out the calculator

Written by: Cindra Drowne-Walsh

The Area command calculates both the perimeter and area of your selections.

Points in space, points on geometry or selecting Objects to calculate the area is done easily within AutoCAD.

Where to access the Area command:

Command Line: type in MEASUREGEOM ↵ (Enter) or AREA will also work

Area 1

Ribbon: Home tab – Utilities panel – Measure drop down – Area.

Area 2

The Breakdown of the Area options: Area 3

Object: Select this when you have an entity such as a Circle, Ellipses, closed Polylines,

Polygon, a closed Entity. Not when you will be selecting individual point on the screen. This must also be selected after both the Add and Subtract area options if you will be selecting a closed entity.

Add area: Select this when you will be calculation more than one area at a time or when you want to subtract and area form the previously selected area.

Subtract area: This is selected after you have added in all areas to be added. This will remove (subtract) the areas selected from the Added areas.

Exit: Brings you into the other Utilities options:

Area 4

*When selecting objects with anything other than straight lines (such as Arcs or Splines) the geometry must be turned into a polyline (Edit Polyline command) – then the Object option may be used. When using the Area command with selecting points this only allows straight line selections.


A: Object

Area 5

B: Points

Area 6a

Area 6b

Area 6c

C: Add and Subtract:

Start with the larger geometry to Add / Object options (select the larger Geometry) Enter when done – then within the same session of the command select Subtract / Object options (select the smaller object to be removed from the area) Enter when done. *Place a Rectangle or create a Polyline so there will be an Object to select

Notice the in the Command line the Total area decreases as each column is selected.

AutoCAD’s visuals are great the GREEN area is the Area being Added and Pink area is the Area being Subtracted.

AutoCAD: The tool palette that keep on giving

Written by: Cindra Drowne-Walsh

Express Tool Palette, Convert to Mtext button.

Mtext is the way to go when placing text (just for the convenience of modifying it later) into a drawing these day, but the Single Line Text is still just click away. If the Single Line Text or if Multiline Text has been exploded the Express Tool Palette has the solution for you to convert that text back into MTEXT.

Convert to Mtext button

Located in the Express Tools tab / Text Panel / Convert to Mtext button


Command Line: type in TXT2MTXT

Command Line sequence to the video it typed:

        Command: txt2mtxt

Select text objects, or [Options]<Options>:

Select objects: Specify opposite corner: 5 found

Select objects:  ↵

5 Text objects removed, 1 MText object added ↵

Note that at the start of the command it offers Options. To access the <options> at the prompt Select Objects ENTER. This will bring up the following dialog box. Displayed is the default and should work for most applications.

txt to mtext options







Selection set order option when chosen, this option allows the user to select the Single Line text in any random order with whatever Selection set method they choose. The text will re-order to the order it was selected. The end results of the text in the video won’t make sense but will show why Selection Set order matters.

The end result is the text has been converted to Multiline text and you now have all the editing options of Mtext available.

* Command input is not case sensitive Lower or Upper case responds the same.
