Interior walls and nested instances when pasting a component

#1

When pasting a group or component on the face of a model I was building results in the solids checker reporting nested instances and interior walls preventing the model to be a solid surface and these components also don’t appear to be exported as they do not show when I upload them to Shapeways for printing. I have studied the tutorials but cannot figure out what I am doing wrong. Any assistance would be appreciated.

Hi Mike,

Your description doesn’t lend itself to identifying the problem.
If you’ll upload the model in your reply we’ll have a look.

Here is an example. The rivet details around the perimeter were copied and pasted from the rivet group setting off the edge in the top left side of the model. When I run Solid Inspector, it indicates they are nested instances and “are not treated as a solid by Sketchup.” I normally export to Shapeways in .dae format. Perhaps in .stl format they would appear as part of the model but as is, they do not.

Thanks for any assistance.

Many of your Rivet components are nested in Groups. You should explode the groups back to individual components.
You also have a hole in the raw geometry of the wall.
The specific section isn’t straight. Plus you need to make that part a group or component for it to read as solid.

I have up grouped al the rivet details but the problems remain. Here is the updated model.

When I export and upload to Shapeways (.dae format), the rivet detail around the perimeter is not there.

It was the same case for the model Box sent back (sidewall rBox).

Perhaps because I am using Maker vs Pro?

Thanks for any other suggestions on what I am doing wrong.

Hi Mike,

On the contrary…
Open and expand Outliner.
Nested inside the parent “2 in rivot” Component is another Component, named “Rivet”.

Make and Pro are equally capable of creating SketchUp Solids.
To do so, one must thoroughly understand what makes a solitary Group or Component a SketchUp Solid.

See this post:



Create a new rivet Component, giving it hole cutting properties.
Component Properties
Arrange the rivet components on the raw geometry of the wall.
Explode the rivet components.
Select All > Make Component and you’ll have a Solid.

Geo posted as I was writing this.
I’m not sure how you are doing it but you have created nested components of the rivets.
Each individual rivet is made of a curved section with top component and then a second flat top added and wrapped up as another component.
If you delete the extra face and then explode the outer component you are left with cup shaped rivets. You can draw in one edge on the bottom to form the bottom face and you now have a solid rivet component.
I have exported this model in .dae and .stl with rivets successfully.

Thank you both for taking the time to diagnosis the issues. Using the follow me tool on a small object like that was problematic and a better plan would likely be to draw it 1:1 and then scale it down to .01" size.

Thanks again

Still not working for me. I opened the rivBox2 model you attached. Solid Inspector2 reports 252 Nested Instances. Exported it and uploaded it to Shapeways. No rivets on the object.

I’m going back to the drawing board with Geo’s advise and create a new rivet. This was just a test case for a train model I was building so I’ll write it off as a learning experience and hopefully do better the next time. Part of the problem was trying to draw a .01" rivet. The follow me tool is difficult to work with on faces that small and likely resulted in some of the odd geometry you are seeing. I plan on drawing a 2" rivet next time with fewer segments and then scale it down to .01"

I don’t know what to tell you but it works for me, here it is on shapeway with rivets showing clearly.

I just noticed another problem in the model you shared.
There’s a rivet hiding inside one of the wall ribs.


With that gone, things work as expected.
