Help Needed adding a parametric dimension to an existing family I made.

[Anonymous]

I'm updating some of our sink drawings in Revit, and I need to make the sink waste parametric so that it can be placed at different distances from the internal edges of each sink. I've attached my Revit family, and the autocad screenshots of 2 example sinks I'm trying to model. Can anyone help me out?

1. First create reference planes and dimension them and put parameters for that dimension.

2. If the parameter/dimension is fixed then use " Type parameter " and

if you want it flexible then make it " Instance Parameter"

See in this sample.. dimensions are given to reference planes..

and 3D model object ( extrusion ) etc are locked to those planes..

Best luck

I'm aware of those basics. My problem is that I'm unable to make all dimensions parametric without having all sorts of conflicting error codes. I need to be able to adjust the bowl size of the sink without changing the size of the counter, and I need to be able to manipulate each edge of the counter separately without changing the bowl size or the edging. Can you take a look at my model perhaps, and see if you can spot the issues? I'd really appreciate it.

You need to lock the radius of the rounded corners in the sketch of the Void Extrusion.

Hi
You should have two family.
Sink family nested in other top counter family..
So that both are separate and can be parametrise separately without any conflict.
