Hello,
yes, actually i think its simple and my initial description makes it hard to follow.
i will try to explain this better.
sect styles.3dm (129.1 KB)
In the screenshot print preview is on and I have set up the layers as if the options i suggest were available (as if boundary width scale is controlled by selected layer etc.)
Layers 1, 2, 3 and 4 have geometry that is sectioned by a clipping plane and we go to each of these layers to set their section style.
Imagine when the section style window pop ups, that we can set for Hatch to have a specific layer. Then everything regarding that hatch is according to this layer, in this case Layer 01 Hatch. So Pattern color is no longer needed, the colors both viewport and print, will be according to set layer [Layer 01 Hatch]. Pattern, Pattern rotation, scale and background stay in this dialog to be set as wished. With this approach it is also possible to control the pen width of non solid hatches according to selected hatch layer, hatches could be turned on/off etc.
For boundary, if we have the option to set a layer, then no other option is needed, since everything is controlled by the set layer, in this case Layer 01 Sect.
Similarly, for Layers 03 and 04 instead of using sublayers, if the option to use specific layers in sections styles exists, we could set for both in Hatch the Hatches layer and in boundary the Sections Layer.
I believe this approach simplifies the UI, adds more control, speeds up changes and is compatible with already existing functionality.
Best,
