Wall corner challenge

[Mahmoud Qenawi]

Hi,

I like to model a cove like this in the wall corner, tried opening tool but couldn't achieve it, I don't know it's a painting finish or special blocks stacked to produce this beauty.

If anyone knows how can this be modelled in Archicad? thanks.

Operating system used: Windows 11

Hi @Mahmoud Qenawi 

If you really need to model every line of the plaster, even the curved corner, then you could use Substract from Solid Element Operations (SEO):

1. Use your prefered tools (slabs, columns and morphs) for modeling the "negatives".
2. Edit> Group those negatives.
3. Select and Convert Selection to Morph(s).
4. Connect> Solid Element Operations...
5. Select the negative group as Operator and the walls as Target.
6. Choose operation Sustraction.
7. Execute.
8. Send the negative group to a hidden layer.

Beware of this method of SEO can result in a slower performance for your file if it is widely used. Maybe you could only substract the curved corner and get the plaster lines based on the building material surface.

Perfect, thank you @Ricardo Lopez.

fantastic way of thinking I really didn’t imagine,

Only more morphs for the whole elevation.

Hi @Ricardo Lopez,

Do you think this facade was created also by SEO? Just guessing.

BTW these photos are captured from Graphisoft Italy’s LinkedIn post.

I would say, probably yes.

But a column and arch could also be modelled with individual components and then saved as an object or a module and then repeatedly placed.

And these days with the segmented column, the column up to the arch could be all done with just the column tool.

Hello @Mahmoud Qenawi

If you refer to ashlar(I hope is the right term), them was realized with the curtain wall tool,

We have a very interesting Webinar on HBIM approach organized by Graphisoft Italia and the architect that have done this model(I can't remeber his name in this moment).....I think that in next weeks you could find the registrati on  the Graphisoft Italia youtube page

Thank you Barry,

I hope this object can be created by paramo it’d be easier to update with design modification & also if segmented column feature is available for complex profile one that will save much time.

@strangeday,

Thanks, sure I’ll search for this webinar & if you got a link for it pls post it here.

Curtain wall tool can be effective also for this challenge despite can’t imagine how it works.

You could also use Columns and Beams to create the grooves. Put them on a wireframe layer with the same Layer Intersection Group Number as the Wall and a Building Material with a higher Intersection Priority Number than that of the Wall, Archicad will apply Priority-based Connections, and they will automatically cut the Wall, no need for SEO for that. The wireframe Layer will enable you to see the geometry of the cutting bodies without them obscuring the geometry of the Wall. After they are modeled, their layer can be hidden.

When you model the grooves, make sure the 3D bodies of those Columns and Beams touch, but do not collide/intersect - that way you will have fewer automatic Priority-based Connections Archicad has to calculate. (Priority-based Connections are SEOs automatically performed by Archicad, just like SEOs a user explicitly performs on selected elements.)

Thank you @Laszlo Nagy ,

I think it won’t affect the overall performance but still the corner void needs to be done by morph & SEO.
