I understand what you're saying better now, but how would a plugin help you with a core like that without being BIM and still have accuracy?

I model the structure core when I need it and xref it in my model.

I do not model hard walls (probably the orange walls in your gif) because those have a lot of details too, like recesses and protrusions in my projects.

Then, there's also the fact that core and "skin" layers have very slight mismatches. Like 2cm plaster that covers a structure wall for the interior. Is that plaster core or "skin"? I'd say neither and this is an inaccuracy that is, for instance usually shown in Skalp's demo videos, and that I don't deal well with.

Also there's the fact that sketchup doesn't cope well with openings. If you have a multilayered wall you must also have a system for making openings on it. Hole cutting components, as you know, are the closest thing we have to opennings but they work on single faces. It's a mess to have double cutting components, but for buildings with lots of similar windows it's a must so you can control interior and exterior with 2 components. Did you imagine how you'd be dealing with that openings issue on both core and skin?

I think Stencil plugin could come in place if one already have two layer wall...
But the purpose of this imagined plugin is to slice true concept phase solid walls which already have defined openings (look at my first picture) and make them structured (at least for a start)! To make it easy to go from concept design phase to "structural" phase...

It would function similar to SU4You Slice tools, but slicing with poly-lines...dividing wall group into two separate groups.

I understand what you want and though it's very rough and probably inaccurate, it could be a start.

I believe fluid's viz plugin, wich is a bit expensive and probably not that intuitive (although it's node based), would probably help you a lot in everything you need. You could sweep surfaces for walls using an interactive polyline, you could subtract openings using interactive Boolean operations and you could probably solve many other issues too.

Why don't you try it?

I know about VIZ tools. I was very exited with IFC implementation for Grasshopper and later hot link with BIM elephants, Archicad and Revit. But,IMO Sketchup is not robust enough to handle parametric modeling like Rhino. Thees are just examples that work in simple models, no chance it will do it on a building scale. It is useful for some fractal generated geometry elements. For the building as a whole, maybe in the future far far away... I am trying to get the best of it now, in a simple way with non interfering tools (parametric software steals focus). This little plugin would be helpful.

There is also a plugin called BIM tools, by Brewskty that somewhat fits your description.

You design a shell, assign wall thickness and it extrudes the shell inwards, by a central axis or outwards, with parametric properties for walls, roofs and slabs. It's also capable of handling openings. I do think you need something else, but it might be worth a try too.

Also, from an outer shell I've tried using JointPushPull for layering I didn't like the workflow though as some times it gave some unpredictable results.

The way I do it is using offset actually. I offset space plans, clean lines then pushpull. It works rather well and I think I could adapt it to a multilayer workflow though I don't like the fact I'd have to adjust middle layers thicknesses.

However, the closest plugin for a wall layer system I can think of is double line, or multi line. It creates multilayer walls exactly as you want (I never used it as I don't need multilayered walls). Unfortunatelly I don't believe these multilayered walls are separated solids but rather multifaces and I don't think they are parametric. You could check it too, though.

Plugins of Kirill2008 ? (Kirill Bannov)
or Tak2hata ?

Thank you very much for suggestions.

BIM tools was nice idea but only experimental. I had the same experience with JPP as you...Double line and SU offset...they are all tools to make composite walls from the start. My idea is to make solid wall in the beginning in conceptual stage, like you do, and to slice existing solid walls into two groups later when structure is needed.

Those are great plugins (TAK2HATA BST even has a tool which works like profile builder 2), but I don't think they have the option of making composites out of existing solid walls.

Yours is a very sound idea that I'd like to see developed. If done right, I'd gladly pay for it as I could probably see it could be a workflow changer.

I would need it a bit more sophisticated though, and at least a bit parametric so it could cope with project changes.

I hope someone figures something out.

I'm glad we understood each other. I posted the request in developers forum.

Parametric for project changes would be great...and far more complex to develop.
I also like being under control, using simple tools which stays out of the way and let me organize information by myself (DOS-Android). For changes, Stretch By Area plugin by TAK2HATA is very helpful.

Stretch by Area is great, but in my workflow i prefer SU's Move and for openings/closets/kitchen design Box Stretch to Target, on FredoScale, by Fredo. It aligns with axis automatically and you have a modifier for double plane stretching. It beats DC component windows by a mile!

I knew about this Fredo tool but never used it in workflow. I have to try it. Thanks for the info.

@Srx - is this what you are referring to in your original post? Do you use solids for modelling the original shapes? If 2x yes, this might be a simple plugin I think.

Ok, I also thought this way, even though I do not use solid tools. Still, dedicated plugin would mean one instead of 6 steps (selecting outline is 0 step in your example). Thank you for good suggestion and illustration.

Edit: or not so simple as I thought. There is no easy offset method for loops / contours in the API. Detecting the upper boundary loop is easy but you would then have to make you own offset algorithm...
