Hi Everyone, I recently started creating dynamic components and was wondering if it’s possible to change the size of the elements without rescaling them. E.G. I have an adjustable shelf used with tooth saw adjustment, so it requires cutouts in shelf corners. Now, if I want to change the length of the shelf incl. the shelf support batten, I’ll end up with different cut out shapes and batten end. Same problem if changing the shelf depth - front moulding and cut outs scaling. Is it possible to change shelf size, but keep the cut outs and mouldings proportions? ![Q3](https://global.discourse-cdn.com/sketchup/original/3X/a/4/a4be216436baa0c503a5dfb39c4445fbd34bb2a7.jpeg) [Q.skp](https://forums.sketchup.com/uploads/short-url/xAFxTBdXO0D6gMEoeXTtnI3rW67.skp) (2.2 MB) I’d be grateful if anyone could help me with that. Cheers! Wojtek ---

You need to make multiple sub components that stay locked in the dimensions they need to be, and move position. Here the corner of the window (with hidden lines @ the seams) only changes in wall thickness, but it remains 3/4”x3/4x”. ![Screenshot 2025-08-28 at 14.09.34](https://global.discourse-cdn.com/sketchup/original/3X/e/8/e8acbca5df2974121fe80667f5df421ca012cb08.png) Here the top of the window can change in length and wall thickness, but the thickness of the board is locked at 3/4”. ![Screenshot 2025-08-28 at 14.09.38](https://global.discourse-cdn.com/sketchup/original/3X/6/4/640c20f8217aba3291b00f619edd08e3a3780340.png) ---

Thanks! It looks almost like, what I’m after, but is there a way to hide the component walls, so they don’t show up in sections? ![Q5](https://global.discourse-cdn.com/sketchup/original/3X/3/8/38d6741daa1ceef789e844782676b4c175c4b96b.jpeg) ---

Hide the faces and the edges where the components meet. Note: if you also intend to get useful cutlist information from this object you’ll first need to explode the bottom level components so it’ll become one object for the cutlist. ---

If I hide more than one face, the component has no fill. ![Q6](https://global.discourse-cdn.com/sketchup/original/3X/3/5/35613d42d362524eeacb053808551a8ff7c8741b.jpeg) ---

Yeah. Only hide the faces where the two components meet, the faces that would get glue if you were making the assembly out of real wood. I’m using Hide from the top of the Context menu here. ![hide](https://global.discourse-cdn.com/sketchup/original/3X/0/4/0480f2afaa48783fa9f838fe168a994758b5e281.gif) ---

I understand what you mean, but for some elements I have 2 or 4 faces to hide. And when I do that, the section infill is gone. ![Q5](https://global.discourse-cdn.com/sketchup/original/3X/7/1/71d869827b3683c9a4ea2cbb51c6ff75efb48435.jpeg) ---

The visible faces should remain unless you are selecting them before hiding. Here I’m select everything except the top and bottom faces before selecting Hide.. ![hide](https://global.discourse-cdn.com/sketchup/original/3X/d/c/dc3436447c95db707c4c6492e633f8db26a9c765.gif) ---

No, this happens, not sure if it is in 2025 or if happened before, but if you hide the faces of a subcomponent it won’t read correctly in the section cut: Without faces of my corner subcomponent hidden: ![Screenshot 2025-08-28 at 21.48.48](https://global.discourse-cdn.com/sketchup/original/3X/d/8/d81159f45675ee092b7fc0bae2792fdbc278ba23.png) With the subcomponent interior faces hidden: ![Screenshot 2025-08-28 at 21.51.05](https://global.discourse-cdn.com/sketchup/original/3X/8/4/842ba5f3d3c1a8fde818d55dbc491f3e7cb01dc6.png) ![Screenshot 2025-08-28 at 21.49.02](https://global.discourse-cdn.com/sketchup/original/3X/5/5/553b03b2c709b196cf8bfcbb9944a69dacb17453.png) ---

You need to rebuild your model with snap settings off, as it leads to incorrect snapping ![Capture1](https://global.discourse-cdn.com/sketchup/original/3X/c/a/ca45c1d9d05d70cf227cd95b907ef6c40bc972cc.jpeg) Make the subs, solid groups, the OCL will not read them ![Capture](https://global.discourse-cdn.com/sketchup/original/3X/1/9/197d0369d7fc5c50b3dc8b9b780994a82032d852.jpeg) later the groups can be outer-shelled, union ![Capture2](https://global.discourse-cdn.com/sketchup/original/3X/b/1/b1ede7a8c81947708e9684879a1efac44b6b3db1.jpeg) Upload the amended component with correct sizes, will show how to progress ---

Ok, not sure why, but after building it new, the section infill doesn’t disappear after hiding faces. Topic sorted. Thank you everyone! ---
