Surfaces glitch

Zaraf — Wed, 24 May 2023 17:31:30 GMT

Hello!
I started a new project in Archicad 26 and i noticed that in 3D my surfaces are acting a little weird.
I saw some fix on another post about it being because my project origin got messed up somehow but that didn't help to get a fix with this issue. You will see in the video I made the coordinates palette that i have some weird values.
Does anyone know how to fix this?

Thanks!

LE: forgot to add that it may also affect the grip points for the elements.

You have already determined the cause of this: You're still to far from the project origin, as we can see in the coordinates down below.

Move your project to the global origin, save, close, and open the file. You should be good now. (This needs to be done for worksheets, too btw!)

I already tried to move the project to the global origin and nothing changed.
Any other reason that might happen?

Well according to the coordinates visible in the video you didn't actually do that? 🤷🏻‍♂️

Maybe you are confusing the user origin with the global project origin?

I guess I am because i don't really know the difference. I'll look into it now, but i gladly take any advice on how to do this properly.

Turn on the 'Coordinates' palette if you don't have it already.

Reset the user origin.

Check the coordinates of your model and if they are not close to zero, your model is too far from the project origin.

This helped a lot. I got it fixed now. Thanks a lot!
Have a nice day!

This problem seemed to have reappeared, i tried to redo the same steps but did not work.. Any reason why this keeps happening?

If you have moved you model close to the Project Origin, check that you have not left something stranded far away still.

Turn all layers on.

In 3D zoom to extents.

If you model becomes very small, you have something far from the origin.

And the problem seems to have reappeared. The worst part is that is ruins my grip points for editing elements and I use 3D viewport a lot in my workflow.
For example, I tried to use a mesh as a ramp because it will have the lower edge intersected with the another ramp..
Any other ideas on how i can fix this?

So in order to fix it i have to check every story and bring over any element left behind, including 2D ones?
I checked for 3D elements and I moved them all.

I don't think 2D elements will affect it - but you still don't want those far from the project origin either.

What working units are you using.

If this is meters, it seems you are 8 kilometers away from the origin.

And 42 meters in the air?

Are you sure, Barry?

I was told by GS that 2D elements in Worksheets are affected, too.

The reason apparently is, that the worksheets are not a seperated entity but reuse the coordinate system setup, so to speak. So the overall coordinate delta will be calculated by making a bounding box over all elements. And the bigger this "box" is, the bigger your problems are getting (losing of precision).

But I might remember it wrongly...

Centimeters.

I think you might be right because i took the time to move all the elements, both 3D and 2D, as close to the origin as possible, from all the views (floor plans, elevations, sections and worksheets) and after restarting the file, now it is fixed again.

Thank you guys for your patience and I hope that this thread will also help others in need.

No I am not really sure.

I just assumed that as they are 2D elements and this is a 3D problem, they would not affect anything.

But I may be wrong.

As I said, you really don't want anything too far away.

Good to know you seem to have it fixed.

And good to know it might be 2D elements as well.

Something to keep in mind.
