Cannot expand two concentric circles

[Anonymous]

Hi *,

this is probably a very basic user question but I am a bit confused here:

a) I have sketched two concentric circles (left side) - I expanded them in order to get a 3d object - all good.

b) I have created a second pair of concentric circles in the same sketch (right side). I tried to expend but I cannot select the area between the two circles which I would like to expand. It does allow to select the separate lines of the circles - but that is not what I intend to do...

Pls. advice what my issue might be and what I could do to get things solved. Thanks!

Best regards,

Alex

You will have to download it since I think you cannot see the issue online, since it is in the sketch 😞

In case you need further details to get me startet, pls. don’t hesitate!

Hi @Anonymous, 

Thank you for sharing your file 

However, I was unable to download your file for some reason. It was supposed to show the download button on the right side. 

Could you share your design after downloading?? 

I look forward to your reply 

Many thanks,

Hey Ahreum,

sorry for the trouble. I hope that I have exported the correct file type?

BTW: I do mean "extrude" not expand 🙂

Best regards,

Hi @Anonymous, 

Thank you for waiting 

Mm,, I have uploaded your file on my project and it seems that is working well so I suspect of your graphics card or driver. 

This is my steps. could you confirm that is correct? http://autode.sk/2ycqHK3

Could you check this option? 

1. Graphics driver installed by up to date 

2. Limit effect to optimize performance option enables. 

I look forward to your reply

Many thanks,
