Fix hatch pattern for slope floor!

[ATranErion]

This has been a problem for years!

When the floor is sloped, the pattern get's all wonky. Placing a filled region on top is a dumb way of doing it, if the profile change, you have to go update all the filled regions. We prefer to use the live model and not put a band-aid on top. 

Autodesk please fix!!

Shouldn't it be better to do UV unwrapping for aligning the pattern. No difficult workarounds. What I would propose is to use UV wrapping and to specify how the pattern is supposed to be warped. The reason is that this workflow should also allow for pattern mapping on double curved surfaces.

With bricks, the bricks can't be warped, so the seams between them will have to be adjusted to compensate. With fabrics, the fabrics stretch themselves. With wallpapers, you add another row and/ or cut rows to shape. These sort of things should all be possible.  I think it would be a good start to be able to project a pattern onto a surface from a plane in space (like Rhino's project). For more difficult scenarios, you would need full-fledged UV mapping and projection methods in conjunction with manual editing to make the pattern look right (i.e. compensate for the seams and joints). In that case, you would need a "Edit pattern" feature to go into edit mode of the pattern to make the manual adjustments in a plane, which will then be reprojected to the model surfaces of choice).

It could also add support for texture mapping for renders (which no third-party is able to add currently). This avoids later rework for renders in a renderer of choice. Which includes VR.

Projection to me is part of the basics, that Revit has never gotten any real modelling commands shows in all of the other areas, including this one.

@Intuos5 I did a rendering of the tiled floor examples and it's not pretty.

The align texture tool doesn't help either.

@Mark_Engwirda  if you facet your floor, and the faces are not all in the same plane, some faces will typically tilt at a steeper angle than others. That means that viewed from above, the same patterns is going to appear shorter on some faces than on others (if you have a face at 89degrees, the pattern would look much shorter from above then on a face at 0 degrees). This is one of the reasons that not in many cases, it's impossible to make a fully matching pattern on a faceted floor. 

[Intuos5]

But if the texture were to be projected from the top view, it would have looked correct in plan. It wouldn't have been physically correct though.

[pieter1]

Right, that's what I meant with "Of course Revit could 'fake it', but that would mean that the plans no longer match the 3D views, which I think is a huge drawback."

[Mark_Engwirda]

@Intuos5  and @pieter1, I would think that it has to be a model pattern if we are modelling.

The main complaint is where the hatch pattern goes completely bonkers e.g. the pattern deforms into an arc as per the original posts.

The second issue is the alignment of the pattern, how does the pattern decide which edge of the model to follow?

You would think that it should follow the alignment of the original pattern as a default so all of the patterns match, even if they do become shorter due to the slope, I believe that it's important that they do.

The third issue with model patterns is not being able to adjust the alignment in a 2d view on a faceted face.

If you need to rotate the pattern you can only rely on the rotate tool which is a little tedious, and not the align tool which would be far more practical. 

The align tool also doesn't work where the pattern appears to be shorter due to the slope unless you go into a 3d view, surely this would be an important benefit if we could do this in 2d views.

We are pleased to say that this has been implemented in Revit 2023.1! Thank you for your contribution to improving Revit!

Thanks for the update @kimberly.fuhrman 

Could Autodesk please provide an explainer on how this works? And, or how we can get it to work?

After an incredibly difficult and painful process to install the 20231.1 update, ultimately had to completely uninstall and reinstall Revit. Then download the update from my online account as the Desktop App failed. 

It appears, at least by default this has not been resolved? Or at least requires some extra steps to activate? 

See screen shot from 2023.1:

@W_Whit I couldn't see any change with the 20231.1 update in regards to the hatch patterns issue, thought I might have been missing something?
Sorry to hear you had such much trouble with your update.

Hi!

It looks like this for me as well. I Tried with different patterns, model/drafting and orientation.

I compared with Revit 2022 and it looks the same. @kimberly.fuhrman is there some further information on how you are supposed to work with your floors to make this work?

[kimberly.fuhrman]

Thank you everyone for the feedback! While yes, the issue with the pattern on a modified slab (by elevation points) was *implemented*, it seems that the one remaining caveat is with a *curved* slab, and this is something that our product teams are continuing to work on. My apologies for the confusion!! Our work here is obviously not done, but ongoing.

Hi @kimberly.fuhrman ,

I appreciate the teams work on this issue and am looking forward to additional releases. I have downloaded 2023.1 and I'm not sure the issue is resolved. See my examples below of a rectangular shaped floor that I modified to test this feature. The drafting pattern is noticeably warped and the model pattern appears to still have warping/alignment issues. The model hatch at least looks presentable compared to a curved shape, though could still use some improvements. If it is in fact fixed for non-curved shapes, is there a setting to address the hatch pattern display that I may be missing?

Thanks!

DRAFTING PATTERN EXAMPLEMODEL PATTERN EXAMPLEENLARGEMENT OF MODEL PATTERN ALIGNMENT

[laurenkschmidt]

A few notes (and opinions) about this "improvement":

1. The entry for this is found under the align tool (confusing IMO).

• On the ribbon, you will see there are new options here. Entire surface is selected by default, so if you go to align your pattern it will attempt to align it.
• This does require you to do the align command twice, once each for the X and Y dimension.

2. I say "attempt" because it is not technically possible to do a true alignment, because it is still a model pattern assigned to many faces. See below for a floor with an "aligned" pattern. The more faces and slope you have, the less your pattern will align.

3. Curved faces still warp, so the effect also doesn't work on those faces.

4. Because it is tied to the align tool, it does not work with drafting patterns

In all honesty, I'm not sure why this "improvement" was released like this. What users want is essentially a flat pattern (no warping, no breaks at split lines, etc). And putting it into the align tool and not supporting drafting patterns seems to be confusing most users who are looking for this.

@kimberly.fuhrman I have found a workaround on curved sloped surface......(1)draw surface as rectangle (2) slope surface as required (3) create in place component (4) draw void (5) cut geometry

[jlush]

@kimberly.fuhrman   Has this been addressed yet?  I have a site with an Ashlar paver pattern in  Revit 2023.  The material gets distorted and warped at slope areas

[W_Whit]

Hi @kimberly.fuhrman, 

With the (assumed) coming release of Revit 2025... can you provide any updates on this request being implemented? Now that we have Toposolids, I think the community would agree we would expect the issue to be fixed for both floors and toposolids. 

We need a complete and proper fix to this issue. The current 'align' function still creates anomalies and minor differences where the patten is not seemless (including the curved edge issue). I'm Autodesk may appreicate these can create large issues for our professional projects.

[W_Whit]

Hi @kimberly.fuhrman ,

I'd have had a look through the release notes for Revit 2025 and I can't find any reference to this issue being implemented. Can you provide an update if I have missed the note, if it will be implemented in a dot update or are we waiting another year?

[kimberly.fuhrman]

@W_Whit ,

This one is still in development. I cannot give a precise date of when it will be completely implemented, but know that this is part of the ongoing work that is being done regarding system family improvements (floors, walls, etc.). Sorry I don't have better news!

[straverSBZ3NW]

This has been as issue for far too long. It needs to be fixed ASAP. I wish I could 1000 times.

2025 release - any updates ?
