Hi folks,
since I make more complex models in SU it often occours that when I use tools such as "Offset" and "Follow Me" that some faces of produced figures are "turned inside"(they are coloured in grey-blue instead of white) and I don't know the reason.
Sometimes I can fix it with playing around but when it works I don't really know why it has worked.
In the attachment is my latest error, I would be glad if someone can explain to my "Why"?
Regards from sunny Vienna

Your answer was the answer! – so it does work and it can be done with the move tool, my two figures where just not centered correctly above each other.
THX you.
Phuu that was a long thread to get finally aware of that.
..and I spend quite some time yesterday to build figures like in Jeans attachment, well I guess it was not pointless, maybe I've learned something thereby
..hopefully 
Jean thank you for your attachment, it made me understand how a transition from a square to a circle works and it remind that there actually is no "bent geometry", everything is done with "angled geometry".
But what I don't understand is why the move tool does not perform the "square to round" operation like in your attachment and instead produces a weird body like at the picture in my first post.
THX you very much for your help.
the "old method" has worked now Curviloft is displayd in SU under
Menu Windows / Preferences /extensions /
and a red juwel apperaed in SU when I opened it after I put the folders in the SU Plugin Directory
maybe I have time to try out Curviloft in the evening, than I will post further errors 
I've never dealt with plugins in SU and I've just tried to install the Plugin Store as olishea has recommended me in this thread to install then Curfiloft, but I already failed to install the Plugin Store.
First I read this: http://sketchucation.com/resources/tutorials/37-beginner/108-installing-sketchup-plugins
But it did not help me. Than I thought maybe I have to put the plugin file at first into the plugin folder of SU, to be able to select then the plugin in the "System preferences" window in SU. Well I did that but it is not displayed there.
Then I saw the menu button "Plugins" but the plugin is not displaed not there either.
... so sad
...Ähh did you want to say (in bad english):
"Curfiloft" is a plugin which is able to perform the operation I'd like to have, the ordinary move tool in SU is just not able to do what I want it to have been done
I want to make a 3d solid with a square as base face and a circle as top face. The transition between the square and the circle should be consistent and smooth.
I thought SU would produce such a transition if i just move the circle up vertically above the square.
But the result is what you see in the picture.
Is this normal – if so why and how can I make the shape I'd like too.
Thank you very much guys!
Yes it was nested. I am quite new to SU and I was a bit overly enthusiastic with selecting elements and creating groups and components without the knowledge that there is the possibility to produce a component in a component.
I've watched some "nesting videos" and I now I am aware of what this is and what it does.
Very cool forum!
Hello!
I want to edit something (apply the follow me tool on a part of a rectangular frame) within a component, but it seems that the component doesn't behave normally.
When I double click the component, the component bounding box appears, after that I start to try to select a single edge, but no matter which single edge within the component I try to select, all the edges get selected at once (highlighted in blue) and I never manage to select a single edge.
Does somebody know where the problem is?
one click: all edges get highlighted in blue
double click: only bounding box appears (if I start to click then any single edge, all edges get highlighted in blue)
triple click: bounding box and all edges get highlighted in blue
Sorry for my bad English.
