Drafting pattern alling with the start of the element?

[mariaZW9XM]

Hello guys.

I created different drawing patterns to use as a cutting pattern. I apply the pattern to the material and use it on a wall with 1 layer which is the material I created (and it looks good, image 1) But when I have another wall with more than 1 layer it seems to be misaligned (picture2) and the material layer with the pattern has the same thickness when the walls has 1 layer. Is there any way that I can solve this?

Thanks.

Not sure what is happening.

• In the top image, it appears that the pattern does not divide itself equally across the entire wall width.(single wall material). This is unexpected behavior.
• In the bottom image, it appears that the pattern DOES divide itself equally across the portion of the compound wall that the material is applied to. (multiple wall layers/materials). This would be the expected behavior.

The top image is how I wanted to look. It is the same material layers as in the image below. Do you know how I can do in order to look in the same way?

[cbcarch]

It will look the same if the two widths of the walls/compound wall layers are exactly the same width.

• What is the thickness of the wall in the top image?
• What is the thickness of the layer of wall in the bottom image?

[mariaZW9XM]

The thickness of the top image wall is 160.

The thickness of the layer of wall in the bottom image is also 160.

They are using the same material. I created the specific pattern for this dimension.

Here is also the revit file.

Thanks

I don't see an issue in your RVT.  Are you just unhappy with where the hatch pattern begins? Unfortunately, there's not a heck of lot that can be done with a drafting pattern, other than changing the "Orientation in Host Layers" - and, of course, changing the View Scale.   

[cbcarch]

If they are both the same thickness, then the top image and bottom image ( in the very 1st post) should have the same number of rows in the pattern--but they don't.
The top image has (2) horizontal rows
The bottom image has (3) horizontal rows.

Are the (2) Views the same scale?

The origin for drafting pattern in a layered wall is always the outside-face of the wall, for every layer.

You have to make a new pattern where every line in the pat-file has an extra vertical shift  ( 1mm for the test-file) , corresponding to the extra width of the exterior layers  ( 100mm  at scale 1:100) , assign the pattern to a duplicated material, and assign the duplicated material to  the central layer. 

Caveat: what you are trying to accomplish, will only work for one scale !!

Sounds like you would like to assign a model pattern (a pattern that retains the real dimensions of the line work independently of the view scale) to a wall structure material, which is unfortunately not support by Revit. See this discussion thread for more: Why can't apply model fill pattern to - cut pattern in material editor

I am guessing that the proposed wall pattern is Cross Laminated Timber (CLT) and you wish to have this pattern appear in general arrangement floor plans and enlarged plans and details.

If this is the case, a solution would be to create a wall structure layer for each ply of your CLT panel. The cut ply material would be a detail pattern with vertical lines spaced approximately to the spacing of the most important scale (typically the largest scale plan view). The ply that is parallel to the plan view would need no detail pattern. For each wall type you would then add the corresponding odd number of plys (3 min, 5, 7, etc). The downside is that the resulting pattern in a section view of the wall will be incorrect as the cut ply won't be in the correction position.

If you don't require the pattern to be visible on general arrangement and building/wall sections, but only for enlarged plans, sections and details, I would suggest you create a linear detail family which has a model pattern assigned that can then be constrained to the wall in the views that require a correct scale and cut pattern for documentation purposes.

Hope this helps,

@FAIR59 

What you propose only works with the following cases:

- the detail pattern is set to align with objects;

- the thickness of the wall layers outside the part with the pattern are of the same thickness since the detail pattern starts on the outside face of the total wall thickness and not the outside face of the wall layer.

@mariaZW9XM 

Using @FAIR59 's solution, you would need to model the CLT part separately from the finish walls on either side (or a required). This would be similar to having a concrete core wall modelled by a structural engineer and the architectural walls modelled by the architect.

By setting up the "core" CLT wall to be a total thickness which is a multiple of n+1 plys of your detail pattern, the pattern should always line up with the two faces. Of course only for 1 predetermined scale (ex. 1:100), as mentioned by @FAIR59 , and orientation (plan/section) of view.

If you want to keep the look consistent, I would built CLT with several layers. Example below how you can make your layer look the same from one wall thickness to next.

[mariaZW9XM]

hahaha yes.. I thought maybe there was a way but it looks like not.

[mariaZW9XM]

yes, they are!!

[mariaZW9XM]

OMG... now I understand it! so much work for such a simple thing... Thanks

[mariaZW9XM]

Yes, thanks for the answer. Before we had the different layers, but unfortunately we can only apply the structural layer to 1 material, not for the entire CLT in this case and for structural purposes it is better if we only have 1 layer with the thickness and assign it as structural. So I'm trying to see how we can get the graphic styles that we used to have.

[mariaZW9XM]

Yes, thanks for the reply. This is what we use to have before  but unfortunately we can only apply the structural layer to 1 material, not for the entire CLT in this case and for structural purposes it is better if we only have 1 layer with the thickness and assign it as structural. So I'm trying to see how we can get the graphic styles that we used to have. But it seems to much work to do!
