Why is`nt my drawing solid?

Postby keknor » Sun Feb 08, 2015 9:35 pm

NSB Type IV mark 6.skp


Hello,

I have tried for hours to make the attached drawing a solid without success. The drawing is 100times the model I want to get 3d printed. I have installed and used the solid inspector. This have helped to find errors, but o the attached drawing it shows no errors. Still the outer shell tool tells me that the model is not a solid. Can someone help me out?

Triple click on it to select all the geometry and make it a group.
It is solid.

The main-part's geometry is a 'solid' if you make a group of it [see Entity Info].
However, if you want it to include the 7 small 'ovals' [bosses?] on the surface of the main shape, which are still component-instances, then you need to do these steps...
You seem to have already merged the 7 ovals on the other side, so you probably know how, but just in case...
Without the main-part being a group [if you already grouped it, then Select it and Context-menu > Explode].
Now Select the 7 instances and use Context-menu > Explode.
They will merge with the main-part's geometry and punch suitable holes that will not compromise its solidity, this is because they were made 'back-less'.
Now treble-click on the whole geometry to Select all and use Make Group on it.
That Group will now report as 'solid' in Entity Info.

Oops. I should look more carefully, saw the raw geometry and looked no further.

Now that I am back on a computer I've had another look, and you have other problems.

You are using layers incorrectly.
Layers in Sketchup should only be used to control visibility and as such only groups and components should be assigned to different layers.
All raw geometry needs to be on Layer0, once you have grouped it you can assign it a layer.

To put it simply, if you explode everything down to raw geometry nothing should disappear when you turn a layer off.
