Thank you both for providing some more insight into this. The sample I had provided was to merely show on a very basic level the idea I was trying to find an answer to. My model is actually very different than this but Alan I appreciate you spending the time to show the process you would follow to build out a box. I guess I was approaching the model similar to actually building the box in real life. Each side piece front and back piece are their own components as well as the bottom and the top. What I wanted to do from there was cut the box as I would with a band saw to ensure a good seam between the bottom (container) and the top (lid), not thinking at the time that it would be difficult to achieve in SketchUp. I will likely back pedal to my components and adjust at that point to construct the full lid as opposed to the piece of wood placed across the top.

Hi pbacot,

Thank you for help. It seems that my issues would be stemming from some items missing faces as you say. I will attempt to redraw faces in my complex model. I typically do make components along the way and once the box is constructed the goal then is to chop the lid from the container, like you would do when actually building a box. I will see if I can find where my internal portions of the model are missing faces and attempt to correct this issue. Other than hiding everything is there a way in SketchUp similar to showing axis lines different colours for parallel to also show faces or missing faces where the case may be?

Again thanks for the help. I will see where I can get with this.

Steve

Greetings.

I am very new to the SketchUp universe as well as to this forum. I am looking forward to learning lots and making some of the ideas in my head come to life. I have recently started designing my own custom cigar humidors and am using Sketchup for a cutting plan and detailed measurements. So far things are progressing very nicely. However I am struggling to be able to split my outside cigar box split to a bottom and a top. Essentially cutting a 3D box within a box to make the concept simpler. I have tried the intersect ideas but I cannot seem to get the "cutting" rectangle to intersect with both the external and internal box. I also just recently tried the Zorro2 plugin and found that the results are the same.

For a very simple example of what I am trying I have attached a sketchup model. There is a 3D rectangle that has within it another rectangle. I have placed a 2D "cutting" rectangle on the group. Can anyone help me understand this process of cutting a top lid from an object?

I am using the free version of SketchUp 8

Thanks to all for tips and advice!

Sample sketchup model for separating a lid from a box

Hello. Steve from London, Ontario Canada.

I am quite new to the Sketchup universe. I came across this wonderful product during my journey into custom arcade cabinet building. I found the tool invaluable in designing/re-designing my plans before taking saw to wood (or MDF in my case). I am currently using the Google Sketchup Version 8 free product and love it. This tool has helped me move from interested in woodworking and designing to actually doing it.

I have only just found this forum as I continue to search for a clear how-to on making a simple 3D box and then cutting a portion of it to make as a lid. I am sure this is rather simple but it has caused me grief to no end. This is for my second project a custom cigar humidor. Again never would've happened if it wasn't for Sketchup.

I look forward to learning lots from everyone here and hope to help others along the way.

Thanks.

Steve
