I’m using Sketchup Web.
I made a component which is nothing more than a notch cut into a piece. Basically, I made a rectangle and the push tool to do the normal thing. It is situated to the top of the notch is flush with the top of the piece it has been put into. Looks great. I made a component out of this. Then I used the component, and the top of the notch seemed to be a minute amount below the top surface - there’s a skin there now. I cannot select it.
Here’s an image of the used component on the left, and another on the right, made by hand, just like the original notch.
Can someone help this noob?
