Default How to get a path from a circle?

Hello,

I'm just working on a model from a plane and become now desperate of trying to get a path out a circle object.
As you can see in the picture I need a path that is about the red drawn line.


Thought a circle would be a good point to start. Just had to adjust the vertices a bit and then I'm done. But when I tried to erase one vertex, hopping I would receive an open path then AC3D just draw a line between the left vertex so that it remains a closed line. Tried all I could find to get it broken (knife, extrude and erase the surfaces, creating objects from the vertices only, unwelding a vertex, line and polyline…) but with no success.
As you can see in the second picture it locked that I got what I was looking for with object 2. But as you see AC3D won't accept that path to extrude a object along it (thats what I need the path for). Is there something special about a circle object so that you couldnt convert it?



Hope anyone could help.

Regards & Thanks

Frank

Nice pictures. If you create a circle then switch the surface type to polyline, you'll see a gap appear. you can then use Surface->change-vertex-order to move the "gap".


Alternatively - draw a line in a roughly circular shape and then use Vertex->spherize to push the vertices into a circle.


The order of selection for extrude-along-path matters. Select the surface you want to extrude first, then the path, then select the function.

Thanks Andy,

the tip with changing the vertex order to move the gap is very helpful. Works for me after I change the mode to line. Guess I tried every else before. For the future I will rotate the gap to the preferred position before placing the circle. But here I had rotated the circle as poly or polyline before and the gap was in wrong position when I discovered how to see it.

Regards

Frank
