Cutting a solid


#1

Hi all,

I have generated a solid and I am trying to trim the solid generated to develop a skewed section.

The solid was generated from lofted curves, the reason for this approach is that the cross sections (will) vary in profile.

I have tried to trim the shape by cutting using a solid generated from a surface in the XZ plane. seems to have done something. I am trying to lose the smaller wedge and retain the remainder the bulk of the solid

Any ideas how to achieve the trimed solid.

Tough and steep learning curve.

Have you tried Solid.Difference? That worked for me.

Solid difference seems to work if you have the right geometry. I generated a XZ plane from which I obtained a surface then generated a solid by using solid difference I got the screenshot.

I was hoping to use the surface as an XZ cutting plane, my original screenshot has a slither which is a 50mm thick solid difference.

The section I am trying to remove is a wedge shape. Using solid difference I think I will need to use more exact geometry which is time consuming. I am thinking about how I would do it in grasshopper and the XZ plane can be used as a cutting plane, which is awesome.

The following image shows the solid difference generated when the thickness is 600mm, I lose a section of what I am trying to retain

Quite tricky in dynamo

Nick solved it with a solid difference, put a boolean toggle in the surface thicken reversed the sign and managed to get what I was after. Not that straight forward. Took ages.

Hi Kenyon,

Could you share your solution please?
Many thanks.

Hi Marcin, I’ll need to dig it out it’s been a while. I do need to get a dynamo licence, but should be able to get the definition to you.
