Transform and remove original geometry

[Pllll]

How can I transform, in my case using two stacked RotAx modules in grasshopper, and then remove all geometry except the final surface meshes?

Asking questions and getting answers is what this forum is all about.

What?

[Pllll]

I have set of surface meshes as input geometry. I want to rotate that geometry and just get the final product out without have to manually delete the original geometry.

2. Be succinct but clear in your wording
People need to know some details about your problem in order to understand what sort of answers would satisfy you, but nobody cares about how angry your boss or how bad your teacher or how tight your deadline is. Talk about the problem and only the problem. If you don’t speak English well, you should probably post in your native language as well as providing a Google or DeepL translation of your question.

3. Attach minimal versions of all the relevant files
If you have a gh file you have a question about, attach it to the post. Do not expect that people will recreate a file based on a screen-shot because that’s a lot of pointless work. It’s also a good idea to remove everything non-essential from a gh file. You can use the Internalise Data menu option to cut everything to the left of a parameter:

Rickson, this is my first question on here. Do I need to explain what geometry is? Or what a rotation is? I literally had to create the script on the right just to rotate an object the way I precisely wanted.

I have geometry

I rotate it

Rhino and Grasshopper keep both. They copy the geometry to transform it.

Is there a module or script or something that I can use to systematically delete the original geometry.

Is there a script or function in Grasshopper to delete geometry?
geometry = a set of surface meshes

[Rickson]

Depending on the workflow you can right click bake to a particular layer, then delete the original if need be.

One way would be to use worksessions to reference in your geometry, then bake into a new file.

Most of the people that answer questions are at work; so posting relevant geometry, overall goal and specific questions will get you answers quickly. Hence the “how to ask effective questions” sticky – it really is important.

I am currently using the right click bake and delete method. I would consider that a manual approach. I am looking for something more robust especially when my geometry is a set of surface meshes and small rotation creates difficult navigation into regions hunting for the right mesh to delete.

bake into a new file? can you elaborate?

The overall goal is to remove the original geometry.

Hi.
See if this helps:

Delete used object

Hi again! [Bake-Replace] Bake-Replace.gh (6.8 KB) I made a small c# script by looking around in other threads (mainly David Rutten answers). This script works with single objects, Lists, but not trees. Please provide same length lists for the first 2 inputs (old and new geometry lists). This script does NOT record on “undo” command, beware! If you trigger it it, it will delete old referenced geo, place/bake the new one while keeping attributes such layer, color, linetype , and also guid (…

I use elefront for these types of operations.

The Bakename will replace any previously baked instances, you can also modify the layer of the original geometry to a delete layer as you bake the new geometry. Easy to demo if you posted a file.

Elefront

Elefront is useful and could be combined with Rhino worksession.
“The Worksession command manages a list of models that are being used as reference geometry.”
