1. ## Faceted curves again

This is another wish to control faceting, especially in 3d geometry operations. Recent posts and many old ones explore the problem from several user experiences. Extrusion, EAP, NURBS curve, NURBS surface, Shells, etc all exhibit faceting. This seems to stem from some software design interpretation of the curves. Curved geometry is generally understood by humans as an analog concept - a circle or other smooth curve is continuous. It has no vertices or facets. The curve can be defined by math. ANY point on the curve conforms to the math. Extrusion, conversion to NURBS, EAP, etc should adhere to the source curve math without creating additional corners or facets! Digital interpretation of curves, including in vwx, is not continuous. Digital depends on plotting vertices along the analog pathway and connecting the vertices with straight segments. The end points of the segments conform to the math definition, but points between do not. (This is less apparent in 2d curves (arcs, polys), but becomes apparent in conversions and use as sources for 3d objects.) More vertices produces a smoother looking curve and less deviation from the math definition. Computers allow plotting myriad points along the analog curve. I’m guessing software (eg Vectorworks) designers decide how many points/segments, balancing performance against curvature excellence. Here is chart with vwx 2d and 3d conversion resolutions pref set to max. It scales, so larger diameters will yield same vertex count and proportionally longer facets. Wish - Lots more points, perhaps 2d and 3d prefs for sooper dooper stratospheric high conversion res? Or some other way to conform more closely to analog understanding of continuous curves? -B
2. ## Naming solids in marionette

I'm using marionette for cabinets. So the bottom and sides, etc are extrusions. I can give a name to a normal extrusion which I can find in my spreadsheet with it's measurements. But how can I give a name to a extrusion in a marionette object? I want to extract the measurements of my extrusions out of the marionette objects into the spreadsheet.
3. ## Creative workarounds to sometimes limiting parametric tools?

The parametric wall tool that is default to VW is nice but I want to know if its possible to take it a step further. I am trying to find a way of distributing objects or extruding custom profiles horizontally and vertically across the surface of a wall efficiently to create things such as flashings or cladding. Ideally being able to click and drag a wall like you would with the wall tool but automatically generate and space specified extrusions or recesses across its surface. On one of my current projects I am using the curtain wall tool to create a second wall on the outside of my exterior walls that represents the 4x8 reveal panels and it works quite well. See attached screenshot. Theoretically the curtain wall tool performs most of the functions I want to do, but it is restrictive. I need to create two windows at each opening to cut the curtain wall as I cannot find any way to combine or link multiple walls so one window cuts through both (Is this possible?). The curtain wall tools frame and panel options are limited and do not allow for the use of custom profiles (custom profiles are a big deal when I need to model something after a specific product). So what I am wondering is wether there already exists or if its possible to create a function or tool (Maybe with marionette?) that functions similar to the curtain wall tool but is more customizable and less restrictive. Another Issue I have yet to find a good solution to is the inability to fillet or chamfer the edges of plug-in objects like doors and windows (or say the edges of the frames and panels of the curtain walls above) without losing their parametric abilities. I do a lot of rendering and having soft edges is important for realistic lighting. I have a feeling all this and more could be possible with the marionette tool, but I have yet to set aside the time to start learning it.
