I am trying to set a template fille up so that ABS fittings sizes are restricted to the sizes on a lookup table. On the template I have transitioned from 100mm down to 65mm. Revit has 'invented' a custom bush that isn't in the sizes I have entered in the lookup table. Is there a way to force Revit to only use fitting sizes from the lookup table?
i.e. this would normally be something like 2 bushes in total to transition between the 100mm (4") to the 65mm (2 1/2") since my supplier doesn't make 100mm to 65mm bushes. The Lookup table used in the bush family is pointing correctly to my custom lookup table.
Not sure about the restriction that I wanted BUT I have found a workaround - using the link below(showing use of IsCustom family parameter) I have made any 'custom' fittings that aren't found in the Lookup csv file appear RED. This is very useful to me.
