Hi, I was re-modelling an architectural model and created a dynamic component for mullions/transoms with one attribute to chagne their depth: LenY. For a few hours, every new component I made, the mullion depths would update if I changed LenY. At some point, I realised that changing LenY on one dy…

I would guess this is an issue with the way your components are created… the best way to get help would be to upload a component here. Otherwise, the best we can do is guess.

Here’s the simple 6-sided box I modelled to create the dynamic component in Sketchup Pro 2020. component-mullion.skp (815.7 KB)

Looking at your DC, I am a little confused. While it does have an attribute, this attribute is not tied to a user control. As this is a DC and not a regular component, modifying one instance will not change the other copies of this DC… this file is simply a cube with a single attribute. Let’s back …

Thanks, Aaron. I set out to create a component that I can easily control the depth of using the “change attribute” feature. I first created the dynamic component. I then made instances of that dynamic component. Initially, when I changed the attribute in the “change attribute form”, all instances …

Herein lies the issue! Attributes are the controls that are used internally to generate the attribute. To actually manipulate the DC, you need to hook the attributes to user controlled Options. Some thing simple like this would only need you to connect your LenY to a user control. Then you can use…

Sorry, Aaron. I’m not understanding. I set out to create one simple box, to then copy it, for example, 1000 times. I set an attribute for LenY to be able to dynamically change the depth of all 1000 boxes simultaneously by typing in a number for LenY. It worked for about 4 hours, and now it no long…

What you need to do is create a component one time. In this component, create the attribute and connect that attribute to a user control. After that has been done, THEN copy it and use Component Options to make changes. Changing the Component Attributes after you copy it is making a new DC every t…

I may be asking the wrong question, then, because I’ve set up my dynamic component just as you instructed before I started this discussion. My question is now: how do you create a global attribute for a component so that if I change the attribute of instance #375 out of 1000 instances, all 1000 ins…

And this still doesn’t explain how each of my component instances mysteriously became individually grouped. Was their a key combo I mistakenly pressed that did that? Any help on this would be appreciated as well.

What you are talking about is just a component. Create geometry, make it a component, copy it. If you change one, they all change. By making a DC, instead, you are adding a layer of data that prevents all pieces from changing together. Your half-formed (an attribute added, but not connected to any …
