Hi All,
I am about to cut out a shape from a cylindrical solid. I have tried splitting surfaces, boolean, wirecut, explode/trim so far, non works.
Boolean ops fail because the cutting surface does not reach over the corresponding solid surfaces. (?)
Wirecut could seemingly work if I could set the cutting angle (a little to Y, Z axis movement).
Could somebody advise, pls?
Hi Gabe- please post the input object - it is not clear to me what you’re starting with and what you want as a result.
thanks,

Hi Pascal,
I have uploaded an image of 2 objects - the right one is what I want to make from the left one.
I found a link - https://www.youtube.com/watch?v=yg2O2RF-7OA - showing an istance of cuttling massives, still, no hint of the name of the tool, and I am not sure it would work with a cylindrical object.
many thanks for your prompt feedback!

Hi Gabe -It really would be much better to have a Rhino file. Your objects look a little suspicious to me…

Hi Pascal,
hope they open and will be of help.
1st image is a box as instance.
2nd image is the cylinder fragment with the contours of the cut intended (upper right corner of the cylindrical object should fall out).
thx,

Hi Gabe - a plane that corresponds to the two lines on your object does not intersect the cylindrical surface the same as that curve you have there - so either the cutting surface is not planar or the shape it makes is not the same - in any case, BooleanDifference the plane in the attached file from the solid - is that about right?

Hi Pascal,
the red curves are the solution. Boolean operations still don’t work but extending the plane does.
thx again!

Hi Pascal,
when I have something else to ask about, am I suposed to open a different dialogue or I may go on with this one?
Anyway, the question is as follows -
I would like to construct a pyramid with possibly even figures for the crease angle dimensions (the four sides of the pyramid.
I extrude the base curve to point and get the solid - is there any means to track or set the angles during the operation?
thx, gabe
Hi Gabe - no there isn’t - I guess I’d work out the angles ahead of time and make the height and size of the base accordingly,
