Stretch an object

[Anonymous]

I am a beginner. Is there a way to stretch a complicated extrusion object which has void cut-outs? I would like Revit to stretch it as a whole, all distance relationships retained. In AutoCAD I would make a block and change X or Y scale in the properties.

It´s not exactly a fast task, but should turns easy when you know how to do this.

Start simples:

1. Go to Architecture/component/model a component;

Make a cube using the extrusion tool;

Use dimension tool (DI) on the cube length

Click on this dimension and, and create a label 

So, repeated for every dimension you want to change. 

You also can do this for some dimension type you simply don´t want to change when increasing the Lenght for e.g.

You can use planting category workaround to get scalable objects, however for more complex multidirectional scalability you'd have to create an Adaptive Component family for that so you can use normalised points etc. Or is it just to adjust parametrically like adjusting length/width and have some geometry follow that? Guess I might be overcomplicating it, share some more details...

a possible approach could be something like this:

• use Dynamo to scale the Geometry: Select Model Element (the Mass) > turn the Element into Dynamo Geometry, then>Scale this Geometry with a certain amount (2 , in my example) then export the Geometry to a .sat File

• In Project's Mass Editor Import the .sat File 
• then in Project you'll be able to use Mass Floors and Wall/Roof By Face

I had in mind this type of object - I do not see your method working for arched shapes. Am I wrong?

My goal was to make this type of object repeated within a family and stretched left and right to fill up certain length with certain number of instances. The height to be constant

It seems to be that I was not specific enough, apologies.

Hi @Anonymous

In this case, you ll have to create an array parameter by last element. You can see this option on options bar when you star the array tool.

And... I still recommend you to do a nested family. If you just want to push and pull an end line, you could create it on a line based family.

As soon I'n on computer, I ll send you some pics if you need.

Alan, I do not understand how this could solve the issue. Could you describe it more clearly, step by step so as I can test it myself?
