Trim floors in GH

Evening grasshoppers! :]

I've been attempting to trim my floors since 8am this morning [its now 7pm!] and am having difficulties!..

I have tried using pretty much every boolean command [under the intersect tab] but cant get any results!

I think my main issues are:-

1] I'm not 100% sure which trim/boolean command i should use
2] I'm not 100% sure which stage of the operation i should insert a trim command i.e. do i trim the initial curves, the planar surfaces of the curves, or the extrusions of the planar surfaces?

Again, I've tried all options but no luck.

An image of the dilemma is below. Any help at all would greatly appreciated guys, I've ran out of options!

Hi David,

As far as I am aware, the intersection is clear. I have tried to execute the boolean using the same objects [and the baked GH floors] in Rhino and it seems to work fine, which is strange.

I'm also currently trying the operation again but with breps made in GH rather than in rhino to see if that makes any difference..

Hi Jali,

I just downloaded your 3DM file and Definition and inserted a Solid Difference component, plus a BRep param referencing your Rhino Objects and it works fine.

I did this using Rhino V4 SR6 and GH 0.6.0057. I notice that from your JPEG the components name is Diff and mine would be SDiff if I had text view on. Have you got the latest version?

EDIT: I've just looked in the file and you are using 0.6.0019
#item name="plugin_version" type_name="gh_version" type_code="80">

Danny,

Thank you very much for that information, as the problem is now solved!! :]

Thanks to all input from everybody..I learned a lot about the boolean and brep components trying to do this and hopefully this thread will help others with a similar problem in the future!

Thanks again!!
