How can cut and make a round-over at my corners

Hi,

I hope you are going well.

Once, I modify my box to have round corner at the top

Honnestly, I do not remember how I did. May I ask to refresh my mind?
I do not want to have big radius, but some thing to cut my 90° edge.
I wunder, if it would be better to have 45° flat face. What would it better, while I print it why my 3D printer. But I thing that a radius corner is nicer, as shown at the picture.

Secondly, I would like to cut my top of the box

The top of my top box will be for radius corder, and the bottom of the top of box that I can increase or decrease. But any way, bot part will be the top of the box

Many thank

What version of SketchUp are you working with? Your profile says Free Web and also 2021. That’s contradictory. Do you mean you are using a cr acked version of SketchUp 2021?

As for radiusing the edges, start with a rectangle with the corners rounded. use that as a path for FollowMe with a profile for the thickness of the box and with the radius corners.

Hello DaveR

Ho, hé, This come back my mind. (I am useing the free web version
I tried starting as the following

But of course, now I have problem with red and green axes.

But I will try as you show

Fix your forum profile.

Why did you miter the corner when it needs to be rounded?

What problem do you have with the red and green axes. There’s nothing in your screenshot to indicate any problem.

Dear Dave,

Many thank to remind me,

I succesfully build my form, but I finall do with 45° Edga

(I am going to correct my profile)

You’re welcome.

Good enough if that’s what you wanted instead of rounded corners.

Yes and I did as you remind me in your previous post (with the video).

Thanks a lot!!!
