Material pattern is not aligned to element

[jagostinho74]

Trying to make the material fill pattern align with the roof elements.

Issues arising on non-regular slopped Hip Roofs and Curved roofs. See image attached.

Debugging done using both Draft and Model patterns.

Draft patterns setup to "Align with Element" (Orient to View and Keep Readeable generated same results).

Draft aligns to curved roof and one of the slopes on the hip roof. Tried to break down the hip roof into multiple elements but results in the same behaviour.

Model gives the exact opposite results.

See image attached.

Model file attached.

Thank you for the feedback

Hi @jagostinho74

With Planar surfaces you shouldn't be having problems with pattern alignment.

With nonplanar surfaces (conical or curved) alignment is a hassel but has workarounds. Is this what you are looking for?

Hello,

Some of the planar surfaces and giving problems.

I have at least a curved one, yes. Which workarounds may I have available?

Have a see at the file attached.

Thank you.

I checked...I don't see a problem with the flat regular plan shaped faces; its just the conical ones where you used an arc; unless I am not understanding what the exact problem is

I used create similar from your roof type and created a normal roof by footprint and pattern aligned perfectly well...I streched and skewed the lines; pattern still aligned with it! So I'm not really sure what to say for Plan Normal Sloped roofs!

For the Conical Faces; I created a new/differnt pattern and I applied to that particular face that aligns the pattern with the base with the base . "Align with Element" option doesnt work for such shapes because there are no obvious/evident plan or surface it can align with I guess. The downside is that everytime the conical shape varries a new pattern has to be reapplied.

If this helps, kindly mark reply Accept as Solution

Many thanks for the screencast.

It turns out that one of the flat surfaces had an arc edge. My bad, sorry.

As for the conical, I do not quite follow what you mean by

"I created a new/differnt pattern and I applied to that particular face that aligns the pattern with the base with the base"

Cannot seem to control the orientation of the applied model pattern to the curved roof.

Thank you.

To align patterns using the conventional OOTB tools like align and rotate; you need to be able to look/use the perpendicular view to the surface with the pattern. With flat surface it is easy to achieve that.

But when the surface starts getting curved it becomes more complex (complexity starts with curved vertical > to curved sloped > to curved sloped with differnt top and bottom radii/radiuses ie: conical > to irregular wavy surfaces). To align patterns on such surfaces you have the following options:

1. Use multiple/duplicate paterns with differnt angls each to suit the particular surface it is applied to (Thats what I used cuz it is not worth the trouble for such small items) Simply duplicate the material and its pattern (in the material browser); reset the angl of the pattern to suit the curve/slope and apply the new material/pattern to the surface using paint tool.
2. (Ideal Method) Unfold the surfaces - ie: make it flat place the patterns the refold them to their shape...This is quite complex for small projects and to do it you need either by using Dynamo, Grasshopper or any similar computational design software

There is a tidious workaround to unfold surfaces in Revit...but to do so;  one needs to take this method into consideration (ie: decide that this is the method you want to use) before modeling the wierd or conical shaped elevations or roofs. It works best on simple internal walls and small elements...If you are modeling a considerably large and complex surface; this method is basicly useless and maybe not applicable (See below Youtube

Fully understood.

Thank you very much for your time and dedication.
