How can I select centre of hole in a component.
Using the tape measure snaps to points on the hole edge but not the centre.
I am trying to position one part relative to another.
I am regular solidworks user & new to SU
thanks
You havenât specified the shape of the hole. If it is a circular hole, right click on the perimeter at the extusion or on the circle in the face and select âPoint at Centerâ in the context menu.
Thanks for that, yes a circular hole & when I select hole edge or hole cyl surface & right click I donât see the âpoint at centreâ option. The components was imported from solidworks as .stl & then made into a SU item, if that makes any difference. I guess I am expecting to be able to identify a centre point or axis (& I know I must stop thinking in SW)
If imported, then the cicular shape is built up of just edges (the segments) and doesnât show the property âCircleâ in the âEntityâ dialog box. Youâll need to construct the center by intersecting two perpendicular lines from the midpoints of two edges in the perimeter.

OK I see that the hole cyl surface has segments & even if I use the soften edges, they disappear visually but I think they are still there because drawing a line will snap to where they were & from that I can identify a diameter line although I guess that assumes an even number of segments ?
I made a simple new item all in SU & the tape measure tool will snap to the circle centre, however I still donât see the âpoint at centreâ option which sounds like it may be useful.
ThomThomâs Guide Tools extension will help you find the center.
You will also need to install his TT_Lib to get it running.
Download these rbz files and then go into SketchUpâs Window > Preferences > Extensions ⌠Install Extensions.

Thanks Chris, that does look useful, I have to do other things now but will try that later
It sounds as if you donât have that ruby script installed.
(Problem with what seems to be such a basic thing is that I tend to forget that âPoint at centerâ needs to be installed, it isnât there right from the start as should)
In SketchUp see that âWarehouseâ toolbar is available. If not, menu View > Toolbars > check âWarehouseâ.
In that toolbar select âExtention Warehouseâ, (last icon with ruby), and find extention âExample Ruby Scriptsâ, created by SketchUp Team. One of its options is âPoint at Centerâ in the context menu for circles and arcs.
Chris, this is cumbersome silliness.
How about putting the good old Point at Center script back in application?
Many (experienced) users have been pointing to its absence for some time.

I will put in your request to add it to the install.

No, it isnâtâŚ
ok guys, with the extension installed I now have the âpoint at centreâ which I think will use quite a bit.
still not working with the imported item but imports from other software usually has some limitations.
I will look at the thom thom guide tools another day.
I note that the point disappear with âdelete guidesâ so it seems to be a reference item only.
Sorry to be comparing with SW but I am struggling a bit without planes, points & axis. Only started with SU this week so have a lot to learn.
Thanks for the help
Bob
There are still yet other center point plugins. This one will get you a center point in a 2D and 3D selection. And thereâs also Center of Gravity.
Telling us - or showing us - about your model could help us give you better guidance.
