To get the Addin’s to work properly, a simple conversion parameter formula is required, to get the units set correctly.
A couple of the Addin’s that require this conversion formula are the ‘DP Randomiser’ and the ‘Set Parameter Values from Image Data’
The example below is for setting a height, but this can be adapted for other parameters.
Because the Addin’s are imperial and set in feet, we need to create a parameter that divides the height by 304.8
1 foot = 304.8 millimetres
The ‘Actual Height’ parameter controls the family and the ‘Height’ parameter is controlled by the Addin.
