Same Material but different fill orientations

bebayaraa — Fri, 23 May 2025 10:02:02 GMT

Hi all,

I’m using Archicad 21 and my project is rotated about 45° on the site. To make working and presenting easier, I rotated my workspace 90°. Works perfect for my layout too

I used a 45° diagonal fill for concrete (concrete) walls. Because of the rotation, I had to set the fill angle to 81° to appear as 45° on the plan. It looks right in plan view, but in section view, the fill angle is wrong.

To fix that, I changed the material fill orientation from Project Origin to Element Origin, so the 45° fill looks correct in both plan and section.

However, this caused another issue: two identical walls now show opposite hatch directions in plan view.

I tried adjusting reference lines, wall direction, and composite settings, but nothing worked.

Please see the attached image.
Any suggestions would be appreciated!

Thanks in advance,
Bayaraa

In the building material settings, try making the fill orientation to 'Project Origin'.

Then all walls using that fill should be the same.

Hello Barry,

Thanks for the reply,

When I try Project origin option, It works on plan view, i can set perfect visually 45 degree hatch ( i had to insert around 81 degree to appear 45 degree hatch relatively to my project orientation ),

but when i make sections ( as long as "sections" don't use rotated workspace )

It became like shown on the image

After spending a full day trying to solve this issue, I found a workaround. I'm not sure if it's the correct method, but it worked for me.

I created two diagonal fills with different angles:

Fill A is for plans with rotated views. (In my case, I set it to 81° so it would appear as 45° in my rotated plan view.)
Fill B is for sections. (Set it directly to 45° if that's what you want.)

Then I created two Graphic Override Rules:

One rule for all plan drawings.
One rule for all section views.
- Criteria: Element Type = elements u want to apply ( in my case = structure walls, slabs, beams ), and Building Material contains the material you want.
- Under "Override Fill Type," I applied Fill B.

Finally, in the View Map, I applied the appropriate graphic override to each view—Fill A for plans and Fill B for sections.

All done in Project Origin, on Building materials section

You should not rotate your workspace, put a north arrow and then rotate the whole model horizontal.

Your hatchings will always remain good.

It is best to always keep the project aligned to X - Y axes and rotate the context and project north orientation. This will also help you draw more accurately in 3D, with the constraints aligned to the main axis.

Now i get it , Thank you guys for the help

I will work this way on the next projects.

If i rotate my project it think it would up all my layouts

Problem is your angled hatch is NOT CMU (Block) CROSSHATCH for BLOCK
