# Square on circle?

#1

How do I draw a square exactly centred on a circle?

#2

you can draw a four sided circleâ€¦

Or a 4-sided polygon with the Polygon tool.

Thanks, but I canâ€™t see how to specify either of the above?

#5

Look at the Measurements box when you select the tool. Select the tool and before you click to set its center, type 4 and hit Enter.

#6

Just a quick one thenâ€¦

#7

How come you donâ€™t have the Circle tool on your custom toolbar?

Having great difficulty sussing this out. One reason is that despite trying to zoom in, my 8mm radius polygon is just a dot. Can I first type in a workspace size, say about 150mm wide? Also is there a beginners youtube video or something that might help me get started with the basics?

You raise a good point! I have moved it to another (instead of copied by accident by the looks), that I usually use just for gifs.

I didnâ€™t notice because I have the shortcut C for it and always use that.

Problem rectified, you have a very beady eye Dave

Thanks for the animation Thorleyan. You have done pretty much what I am trying to do, but I want the side of the square to be the diameter of the circle 16mm. Also in a workspace I can see it.

No. But you can zoom in on your circle using the scroll wheel on the mouse or the Zoom tool. The scroll wheel is easier and a better option.

#12

Start drawing the polygon and then hit Ctrl. Drag out a bit and type 8mm and hit Enter.

You could also draw the shapes (a four sided polygon and a circle) then register them using the centre inference - a polygon, like a circle, has a centre inference point in SU 2016 and above.

Your profile doesnâ€™t say what version of SU you are using.

Thanks, I have just downloaded SU2017 pro trial. I was going to hand draw with ruler and compass etc. a small metal item that I need to get machined, but feel it would be very useful to have it in 3d using Sketch Up. I really think I need to study a basic beginners video before going further. A URL would be useful.

Marvellous thank you. I will have a study at that and hopefully come back here with more intelligent questions

When the Pro trial expires, it will stop working unless you buy a license.

You should download Make, if your use is non- commercial, and if that isnâ€™t what you got in fact - it also gives you a trial period of using the Pro version
