Creating solid 1

[Robert000]

Hi,

I have created a rotated surface of 2 lines,
which are the parts of circles with different
radius(ofsetted distance 1,05m).
In groundplan the angle between these lines is 15 deg.
It isn´t possible to extrude this rotated surface.
If I could cut away the volume of sphere determined
by this rotated surfaces from both sides (symetrical
problem, the solid I need is determined by 2 surfaces and
a sphere) i could get the solid between them.
Is it possible? How?

Thanx,

Robert

Hi Robert,

Use the region command to convert your rotated surface into an extrudable object. Then you should be able to create your sphere and the subtract or union your newly created shapes to get what you want.

Hi Todd,

it isn´t so easy, i tried it before.

Here is the computer´s answer:
1 closed, degenerate or unsupported object rejected.
0 loops extracted.
0 Regions created.

The circle 2 was created by offsetting the circle 1.
Then one of them was rotated in groundplan(15deg).
One end is an intersection (in groundplan, the
height is different!!!), the second end is free.
Ruled surface was created from curved lines.

You can try it with quartercircles. Ofset one of then,
then rotate in groundplan.Then create a ruled surface,
region...

Thanks,

Robert

Hi Robert,

Sorry, I thought these were all on the same plane.

If you need to convert a surface, goto

or

http://www.cadshack.com

and search for a lisp routine called M2s.lsp. This will convert polyline meshes into solids but they will have a thickness, but then you can work with the newly created solids.

Hi Todd,

I found a lisp routine on:

Thanks a lot. It was a useful help.

Another way:
Construct a sphere with the SPHERE command.
Use the SLICE command to divide it on the desired surfaces.
Throw away what you don't need.
