Family - with Dynamic array that expands with parameter dimensions

Anonymous — Tue, 26 Feb 2019 20:48:20 GMT

Short version -

I'm creating a massing Family with grips - to extend the width and length.

I'd like "model lines" to act as Grid lines to populate inside automatically on a defined dimension. (50' for example)

I'd like an array function to be associated to the overall lenght / width of the building and fill in the "model lines" while it stretches.

So - instead of telling the array to give me X equally spaced lines... I want the array to fill in a line with items at 50'.

This would be more like how a stair adds treads... the length of the stair may chance, but the treads maintain an equal spacing.

You can assign a parameter to your array.

Create a parameter that reads/sets the length of your item.

Create a parameter that sets the spacing.

Length/Spacing = 'parameter assigned to your array'

Hello

use inbuilt divide surface..

there are so many options once you choose pattern..

and many parameters ...

have a look..

Select the surface of mass.. Divide surface.... ( you dont need to reinvent this feature cause its implemented pretty well within massing )

Various option using surface pattern

and if you know how to assign 1. Instance Parameter ( Number, Integer ) or 2. Type Parameter, you can control those in the project once these Revit Mass families are loaded in the project...

cheers

Best luck

Thank you all for your efforts to help - I think my original question wasn't specific enough. I've created an image to help.

First - my intent is to create a Site Plan component, that can be used for various projects of unknown sizes. Ranging from small to huge.

I may be referencing the wrong "tool" when I said Array.

When I grip the ends of the component and make it 300' wider, I want it to auto-populate new Grid lines inside, set at a designated spacing (50' for example).

Since the perimeter or the object will change - getting the model lines (grid lines) to show correctly once isn't what I'm looking for. I'm trying to program the object to respond correctly when manipulated.

Hope that helps clarify -

I think you are talking about something like this family. Load it into project and you'll have grips to size it dynamicaly in the x and y direction. "s" parameter (or grip) can control spacing. You can also make it so it has grips in 3D view as well.

Use a inbuilt Structure Beam system as a trick for 3D array / reference parametric model... reference image and screencast uploaded..

beam system - custom profile, associate to level, tilt at any angle...etc..

I think everyone gives you a right answer, though they are different. Attached is one approach.
