Rotation axes

Anonymous — Wed, 06 Aug 2025 15:04:16 GMT

Hi all!

Why is not possible to change rotation axis? Why can I rotate object in all axes (x,y,z) without transfer it to the morf? This is really big disadvantage compare to Autocad.

Thank you

What is it you are wanting to rotate?

Walls and columns can be slanted.
Beams can be inclined.
A rotated slab is a roof.
Objects can be rotated if it has been scripted into them - or there is a 'rotate' object floating around somewhere that can rotate any object.

Hi Barry,

I tried to rotate the wall. I had to transform it to the morph. Then it worked. Anyway: My problem is this:

I need Alu profiles to my project: https://alwitra.de/en/aluminium-profiles/roof-edge-trim-profiles/

There is possibility to download it (just at the end of website) in several formats. I downloaded it as DWG file and import it to the Library. I need to rotate it around X and Y axis. Only possibility is the morph again. Any other idea, please?

I think we may have a problem with terminology?
By 'rotate' do you mean extrude a profile along a path both horizontally and/or vertically at the same time?
If so then the morph 'Tube' option is what you will be looking for.
Depending on the path direction you need to take, you may have to break it up into short line segments because I don't think it is possible to stretch along a path that curves in 2 directions at the same time.

If you can show an image of what you are trying to do we may have some more suggestions for you.

You have to be more precise if you want to have a good answer... You start to talk about objects (which are placed in embedded or loaded libraries), now you want to rotate a wall...
If you want to compare Archicad to Autocad do it, but keep in mind in Autocad everything is "morph" or 2D, while Archicad deals with architectural elements ! That's why you can't rotate a wall along the x or y axis.
By the way it's possible to tweak objects to be rotated differently but I think it's not what you want I think.

Hi guys,

thank you for answers. Here is my problem:

The first picture is an original one. As you can see, I need to rotate Aluminium profile like on the second picture (rotated in Photoshop). How can I do this? Only possibility is trasfer this Alu profile to the Morph. Am I right?

By the looks of it, you could model your aluminium profile as a Complex Profile then extrude it as a Beam along your roof edge.

If it just a simple straight run then it may be best to create a complex profile beam which you can then incline.
Beams will trim if joined at corners - but not so well when they are sloping.

This is when you would use a morph and rotate it to match the wall.
Then you can select the end face and tube it along the walls and around corners, up and down - even curves.

Just thought another option these days in version 21 is to create a railing with a custom profile rail and run this around your wall.
Here is a quick 1 minute test.

Thank you. I will try the rail profile. I do not know Complex profile. I have to study it.

Not so cool

Why is such a big problem to add the feature "rotation by all axes" to the Archicad? Graphisoft should do this. It will make this SW much more suitable.

ArchiCAD works with a system of building objects that have defined properties. For all things that fall outside these categories, there's the morph tool, which you can freely do just about anything. There's also the option to convert objects made by other tools into morphs.

There is not much you can't do with the rail tool.
I created a profile that was horizontal, so on the sections of the roof that are angled I had to set the angle of the segment so it was 90° to the roof slope.
I have left the railing node posts on in this image - obviously you would change them to 'invisible'.
