Modelling and drafting in ARCHICAD. (Example: How can I model a Roof soffit/fascia?)

I am doing a series of simple operations (subtractions), using morphs as operators and slabs/walls as targets. The results show in sections but not in any of my plans. How can i fix that?

SEO's have never shown on plan except for Morphs. Only workaround is to convert to Morph the other objects too with the problems that action brings.

There are no changes in this regard in ARCHICAD 23, as far as we can figure out from the AC23 announcements. No mention of any development in this area.

Shell, Roof, slanted Columns and CW (when set to projected) are also projected so will show SEOs on the Floor Plan.

In AC23, Beams now have the option to be projected (in addition to existing symbolic representation).

Using projected method does have a performance hit (needs to calculate the geometry from 3D before drawing it), so will be a bit slower than symbolic elements. Symbolic also uses real arcs/circles for curved elements, rather than projected which will show the segmentation as in 3D.

seems like a really simple request and SEOs are visible in sections so i dont get why not plans also. Anyway, i would like to avoid using morphs and breaking the parametric aspect of my building. We are building a house made of stone with arcs and vaults and other more weird geometries that occur in our solution so solid operations are a necessity im afraid.
If i used morphs maybe i could build them through grasshopper and maintain everything under control externally? but then i am a bit worried about the classification and the properties of this resulting geometry, because now i still have Walls I can put windows and doors and its all within a controlled system...im trying to understand the disadvantages of having everything morphed. Any tips?

That is because plans are not a true 3D projection, while your sections and elevations are.
You could maybe try a 3D Document based on a 3D top view, but this will have other issues as you will find - you may not like the way some objects are represented for example.

I have no idea really when it comes to Grasshopper as I don't use it.
But as I understand it you are not manipulating existing elements in Archicad, but you are deleting and replacing them with modified version.
Converting elements to morphs in Archicad is fine if you are at the end of the design process, otherwise they can be a bit of a pain to edit if you still need to make changes.
It all depends on the changes you may need to make.

Sections are projected from the 3D view, hence they show SOEs much like the tools that Jame's mentioned.

If your arcs are consistent, you might be able to use a custom door/window to achieve your desired floor plan without resorting to morphs or GH.
