I would like to do the following programmatically in Ruby: select a section plane by choosing one with a specific name create a group of section lines using Sketchup’s native “Create Group from Slice” feature or similar name the group something predictable for later use/retrieval fill all of the s…

See previous topic thread … [image] Outliner create slice group via API, somebody can help? Ruby API Sorry, I got confused with the word Outliner which is the object tree panel. Okay, the “Create Group from Slice” command is an edit command, whose command ID will change …

Thanks Dan but I was looking for “under the hood” info on Section Planes. Nonetheless, I muddled through so below is my Script. The idea here was to do sort of a Skalp Lite that makes a very remedial Section Plane we can use to distinguish between existing (EXIST) and proposed (PROP) geometry in o…

[image] hank: $target_phase Don’t take over patterns that you see elsewhere or in other languages (the others apparently do it like that, so it must be done like that) without understanding what it means and whether it is applicable (or needed) in the context where you want to use it. This s…

Will do! Thanks so much for the tips!

I believe if I have several defs in a single module that all need to access Sketchup.active_model I should used @model = Sketchup.active_model correct?

@ variables are meant to capture “state”, that is values that are needed to remember the the history of the object so as to define how it will respond to future methods. The downside of overusing them is that you need to know when and why they were last set, and if they really aren’t essential to s…

So to summarize (because I don’t understand all of that), I should call model = Sketchup.active_model inside each def correct?

model = Sketchup.active_model @faces = model.number_faces # you may want to update the face count, but not change model... def count_faces(model) @faces = model.number_faces end john

Here’s an example of a legitimate use: if you set @model in an object’s initialize method and assume that the object is unalterably tied to that model for the rest of the object’s life. The danger in that case is to be certain that the object doesn’t outlive the active model. This especially true …

Not worried about performance, just code clarity and really scripting convenience. In PHP you can set a global and be confident that it will be available to you until it is killed or updated. Seems weird that it’s frowned upon in Ruby or at least SU Ruby. My other thought is, why WOULDN’T you wan…
