Hi there, I have a rectangle which i have extruded. I then draw an arc on the corners and push down so i now have a rectangle with rounded corners. Lastly i want to use the roundcorner tool to give the external edges all a radius. It works fine, apart from the fact the main face inside of the rounded edges now appears to have two tones. When i put through rendering this shaded section is still visible. I have turned on hidden geometry and nothing is shown, it just seems to affect the solid face. I have found a work around of using the round corner to do the initial radius of the corners of the rectangle, and then roundcorner on the external edges. However when i have had a more complex object such as a counter top with a sink cut into it, this issue continues to happen, and I don’t have a work around, it also erases small slices of the face, which i have to go back and fill in…very odd. Anyone else experienced this, and has a work around? Thanks 
I’m not sure what you are describing. Can you share a SketchUp file that shows it?
Hi Dave,
Sure no problems, here is a file i have set up with two examples showing the issues i’m having.

Hi Dave, you have saved the day, i have never played with the setting on the tool bar as it isn’t an issue i had previously, really appreciate this
This isn’t specific to FredoCorner but it’s often a good idea to hide those edges at the limits of the rounding no matter how the rounding is created.
