don't think: Do Revit: +/- offset(s) for families

don't think: Do Revit: +/- offset(s) for families:

'via Blog this'

Step by step solution to +/- offset values for families.

Parallel to the reference/surface point(A):
  1. Create a reference plane in the + offset direction,
  2. Call it "REF.OFFSET+"
  3. Dimension from the reference point(A) to the plane.
  4. Give the dimension a parameter "OFFSET.FRONT" (group it under 'other')
  5. Between point(A) and the reference plane, create another reference plane.
  6. call it "REF.OFFSET-"
  7. Create a dimension between the reference plan from step 1 and the one just created in step 3.
  8. Given the dimension a parameter "OFFSET.BACK" (group it under 'other')
  9. In the family properties, Create a Length parameter called "OFFSET".

  10. Next to the "OFFSET.FRONT"  under 'other' group, add the formula:
if(OFFSET > 0', OFFSET, 0')

  11. Next to the "OFFSET.BACK"  under 'other' group, add the formula:
if(NOT(OFFSET > 0'),abs( OFFSET), 0')

Try flexing with 1'-0" and -1'-0" to make sure it works properly.

*Make sure you reference "REF.OFFSET-" plane as that is what flexes forward and backwards!
