Edit a Hole

Edit a Hole (post #170424)

I have a leg component.  I "drilled" a 1/4 inch hole into the leg for a peg.  Now I'd like to change it to a 3/16 hole.  Is there an elegant way to do this other than just removing the hole and making a new one?

SketchUp help talks about using the move tool and placing it on a cardinal point of a cylinder to reduce the radius.  I cannot locate a cardinal point on the hole.

Unless it has been exploded, youshould be able to hover around the edge of circle with the Move tool and find the cardinal points. And unless you want a tapered hole, you want the cardinal edge instead. You should find those cardinal points and edges at 90 degree intervals around the circle.

Another way to do this is with Offset and Push/Pull. Since you want to make the circle smaller, use Offset in the bottom of the hole and pull the ring up to the surface. Then delete the edge of the original hole.

This method may not be quite as elegant as using the cardinal edge but it can also be used to create counterbores and other sorts of details for which the cardinal points and edges aren't available.

I'm sure I'm doing something wrong but just can't get to a cardinal point.  The offset method works great, though.

I know it must be frustrating, but I would forget about this method using Cardinal Points and Lines. I recommend just erasing your holes with the eraser. When you click the eraser on the circumference (on the top and bottom surface. The faces will fill back in automatically. Then re-do the new sized hole and use the Push Pull Tool to make it a hole. 

If you want to save the first hole's center to help placement of the new hole, just right click on the circumference and pick  Point at Center then place some guidelines to save the center position before deleting the hole.

VAM, when you click on the edge of the hole with Select do you get the entire circle highlighted or only a single line segment? If it is the latter, Cardinal Points/edges won't be available.

Although I disagree with Tim about forgetting cardinal points, since there are other ways to deal with it, you have some options.

The hole is in a component and I've chosen "edit component" before I click on the edge of the hole.  The circle has 24 segments.

Perhaps you could send me the component and I could take a look.
