I hit a snag with opencutlist, when I to generate parts list, one section of my piece does’t come out right. It says “cross section unidentified” but all other pieces are correct when i generate. I was hoping someone could help me figure it out. I’ll upload my project and i hid everything else to show the part I’m struggling with. Thanks in advance. ![Screenshot 2024-06-28 at 4.47.22 PM](https://global.discourse-cdn.com/sketchup/original/3X/6/4/640b10571acb3d17ed4cda1a62fccfd7f3ed51f9.jpeg) [Terrace Raised Garden.skp](https://forums.sketchup.com/uploads/short-url/wvFmnOOQbE4feB1PjJrt0I60NM4.skp) (462.8 KB) ---

Which one isn’t showing up? The one on the end that is just loose geometry? ![Screenshot - 6_28_2024 , 6_51_08 PM](https://global.discourse-cdn.com/sketchup/original/3X/9/9/99ac92d0923406a390c8321e204e270ff03d1d05.png) Or the one that is not a solid group? ![Screenshot - 6_28_2024 , 6_53_51 PM](https://global.discourse-cdn.com/sketchup/original/3X/1/9/1970d869da50392e9dcc5120dadbea79e7345cd2.png) ---

Thanks for the reply! Both of those are showing up with CutList but only when I join all of those into one component but when I do join them Cutlist seems to see them as one big rectangle instead of trying to cut out each individual board. ---

What happens if you make the end one a group instead like the others are of leaving it as loose geometry and then in the non-solid one, delete the stray edge? ---

I just tried doing that and it didn’t seem to matter ---

I might’ve figured it out. When i was copy, pasting, and moving i must’ve extended one board a tiny bit so that the dimensions were wrong on the rest and messing up cutlist. I’ll get back on here and update if it worked or not. ---

Hello, As I can see, all your parts are subgroups of a component. **OpenCutList does not consider groups as parts.** So it considers the whole component as a part and it measures 58 7/16 x 11 9/16. **→ You need to convert each parts to components.** But be careful that dimensional material are **grouped by full section**. So this will produce this kind of result : ![Capture d’écran 2024-06-29 à 07.51.34](https://global.discourse-cdn.com/sketchup/original/3X/6/d/6dfbca1c17d31aca55cf4559ec66a90f18f67d49.jpeg) * * * 💡 Loose edges is not necessary a problem because OpenCutList compute part size by measuring only faces bounding box. ---

You were right about the boards, they did need to be individual components and I also needed to change their dimensions to match the dimensions in cutlist. Thank you for your help and advise! ---

I am also having trouble. I read through the posts, including the solution, and I am either still doing it wrong or don’t understand the answer (I am honestly not understanding the solution description or graphic, so I am sure that is part of the problem). I am running into the same message and I made sure the component is stand alone (not part of a group) and the material is dimensional, but I am still getting the error. It is also not giving me the length, width, and thickness. It appears it is trying to give me length twice. ![Top v5.1](https://global.discourse-cdn.com/sketchup/original/4X/8/1/8/8186344d27ddf1746a2726d7c03356200597b6e2.png) ![Top v5](https://global.discourse-cdn.com/sketchup/original/4X/2/c/1/2c14a2d5893e6cec7b0d03fb26416dc568d39672.png) ---

I would like the cut list to display length, width, and thickness. I would then like the cut diagram to put both boards on 1 piece of wood, if they fit. The example I made are two distinctly different boards. I would like the cut list to display their length, width, and thickness, and be able to put them on 1 cut diagram, so I can optimize the cuts. Right now, I can only figure out how to put boards of the same width together. In this example, I can only create a cut diagram for each individual board, but I want to have OCL display them both on one board, since I know they will fit. ![Example 3](https://global.discourse-cdn.com/sketchup/original/4X/5/e/c/5ec1cd8c3428c22486ebf13bea5927c3d9b3f5fd.png) ![Example 2](https://global.discourse-cdn.com/sketchup/original/4X/1/3/b/13b5930898752746d1f6ea680f17ca0f0fa6c6a3.png) ---

The _Dimensional_ material type is designed for parts with a **fixed cross-section**. By definition, **it does not group parts with different cross-sections**. It can represent everything you will only cut in **ONE** direction : the width. So, if your parts have a common thickness but variable lengths, you should choose the _Sheet Good_ material type. And if your parts do not share any dimensions (length, width, thickness) : no cutting diagram available…
