Model surface hatch pattern for common brick bond

[toddAD3E9]

I'm looking for a specific "Model" hatch surface pattern.

I work predominantly on the redevelopment of historic textile mills most of these mills use a common brick bond (American bond) with header courses at every 5,6 or 7 stretcher courses. Since I work with the Federal Historic Preservation Tax Incentives program and the difference in elevations vs renderings come up from time to time, because of this I would like to use a Model hatch surface pattern so that it matches the render material and view correctly at any view scale. Importing a custom AutoCAD hatch doesn’t work because they are only available as static drafting patterns.

Thx

If you have the AutoCAD hatch pattern you can modify that and use that in Revit as a Model based pattern. You just need to update/add a line of code to the pattern to tell Revit it is a Model based pattern. Here is an example of the code. 

Sometimes when creating a new pattern in Revit you might have to use the Scale option when defining the pattern so that it shows correctly in Revit.

Hope this helps.

Another option is to use PyRevit. Draw the pattern exactly as you need it, and then convert it into a pattern with the Make Pattern tool.

You might benefit from adding on PyRevit (free) or PattyCake ($) or some other pattern generator.  FWIW.

Thanks for sharing. Very cool. I see that only the basic patterns are free. Looks very good and simple to use.

As Tom Kunsman said above the simple modification to the pat file is working great, the problem is I can't seem to get the headers too line up correctly horizontally to the stretcher's. Its been way to long since I've screwed around with pat files. 

In the image the red circle header should not align, I want the hatch as shown in the green the green. It is just line work but shows it correctly.

Tom, I forgot to post directly to your solution. On track but having a problem aligning the header course in the pat file. see my last post image at the bottom.
Thx

You can align patterns, you know. Do Align > select one line of the lower pattern that is correct > select one line of the upper pattern that is not correct. Done.

there is no 2" offset in the hatch to align all the header courses, if I draw a line for reference it just moves the entire surface hatch.
I just need to figure out which numbers in the pat file to change to 2" offset, this would slide the header course into the correct position.

Designing hatch patterns using notepad was a thing in the past.  Nowadays there is abundant of tools (some good ones have already been mentioned here) to do it visually with ease.

[toddAD3E9]

I figured there was a easier way. Only reason I was fumbling with this method is that I did a lot of custom pat files back when I used AutoCAD many years ago and thought it would come back to me...lol
I'll check around for apps and plugins

@toddAD3E9 give us a try.

For completely free (yes) you can see your changes if just writing one out by hand. I always found the immediate feedback loop better than text editors requiring you to load in the changes to see the result. A couple of our members still write them out by hand, but use the free version to just visualize it in real-time.

Feel free to reach out via hi at pattycake dot com for further help too if you need.

I liked some of the free tools but sketching by line was limited on the free versions so I ended up doing some research. If anyone is interested here is the pat file for Brick-Common Header every 6th course.

Enjoy

If you have a half cilinder shape pilaster, how can you make the aligment?

[barthbradley]

Are you asking how to align the vertical lines when the pattern is on a curved plane. If so, you can't. But try this: In 3D View TAB select on a vertical line in the pattern and then press Rotate.  You can then Rotate the vertical line to where it should be.  

[ToanDN]

Align the pattern of the flat surfaces to match the curved surface.
