You can very easily choose to plan your build in either Cm or Inches either for all objects placed or for specific ones when needed.
SELECT YOUR MEASUREMENTS BEFORE YOU START
Go to SETTINGS > OPTIONS in the vanspace Toolbar
Leaving the Tick in USE METRIC MEASUREMENTS will give you CM
Removing the tick in USE METRIC MEASUREMENTS will give you Inches
Once you have made your selection, click CLOSE and RETURN TO VAN
CHANGING MEASUREMENTS FOR A SPECIFIC ITEM
In this example in OPTIONS as shown above we have selected to use Metric Measurements however, the particular item that we would like to place is shown only in inches in the description when wanting to purchase
We did not want to change the entire layout, just to resize this one particular object.
When you have placed your item in your van layout click on the object so that the Gizmo appears and the measurement box on the left hand side
You can then simply click in the bottom field to toggle between CM or Inches an manually enter the correct dimensions.
CHANGING ALL MEASUREMENTS AFTER OBJECTS HAVE BEEN PLACED
If after placing multiple items you wish to change from CM to inches for all Or Vice Versa, you can do this again within SETTINGS > OPTION
1. Untick or Tick the current option, in this case we were using CM and have now unticked USE METRIC MEASUREMENTS then Close and Return to Van
When back in your Layout you can then click on any object so that the Gizmo appears and you will see that the measurements are now showing in inches
If this does not happen immediately after resetting in OPTIONS please exit the software and reload for the change to take affect.
