AutoCAD: WBlocks (Write Blocks) adjust to the Insert Unit

September 18, 2015

Do you use different forms of units within your projects/company and want to utilize your WBlocks in all projects quickly?

Example. A projects is Decimal Units and another projects in Metric Units, you have WBlocks created in Decimal Units and want to utilize then in a Metric unit DWG.

Steps to take for the conversion to work seamlessly.

1.When creating a WBlock make sure a form of units that applies to the WBlock is defined in the WBlock dialog box / Insert Units drop down area.

*In this drawing example the WBlock Insert Units are set to Inches:

*Here is the WBlock example, Switch Plate drawn in Decimal units, the Insert units defined as Inches in the Write Block dialog box.

WBlock-Imperial-units-3

2. Open the next Drawing define the Insertion Scale found in the Drawing units Dialog box. Ex. Millimeters…
Drawing-Units-Millimeters-4
3. Insert the WBlock: The conversion happens automatically.

WBlock-Metric-units-5

Imperial Units:   X   the metric conversion of Millimeters (24.5)

2.750    X       25.4   =       70.6120

4.500    X       25.4   =       114.3000

The suffix mm was added – within the Dimension Style manager / Primary Units tab / Linear Dimension area.

Hint: When creating a WBlock for your library stay consistent with the form of units you create them in. If you and your co-workers know all WBlocks are created in Inches they will know to check the Insertion Scale if inserting into a drawing with units other than Inches.  Inches is the example option I chose to use your type of work will direct that choice.
