Model Patterns

DrakeCanyonArchitecture — Sat, 14 Sep 2019 22:11:58 GMT

I'm a little shocked that it seems almost impossible to find the same patterns in both drafting and model formats. I've found the method of adding ;%TYPE=MODEL% to the .pat file but this seems so clunky, not to mention that there are scaling issues. What is the best way to handle this?

The reason that I decided to mess with this today is that I discovered that model patterns stay aligned with and proportionate to the object that they are associated with, in my case it was shingles on a roof. I'm not sure why anybody would want it any other way. But now I have all these patterns that I would like to convert to model and it seems as though it is going to be a time consuming project. It would be awesome if there were an option to download patterns in either drafting or model. Any help would be very much appreciated.

Try to open the pattern file in Notepad and see if you can edit the type.

I've done that with some success but it seems to be hit and miss. Some of the patterns that I'm dealing with are stone and there are a million values in the .pat file.

Why don't you tell us what model pattern you are looking for, or post a picture of the drafting pattern you have? One of us may have it. Also, I find a sh*t load of stone model hatch patterns at Arcat and El Dorado Stone. Have you tried one of those sites?

Here is a picture of the same stone hatch, this one I got from Coronado (I haven't checked out El Dorado yet but will). The picture to the left is the pattern in it's native form as a drafting hatch, the one on the right is the exact same hatch that I modified the .pat file so that Revit would recognize it as a model pattern. I have a ton of stone patterns as well and I suppose I could just use them as drafting patterns and make it work. As I understand it though, you would want to use model patterns on your actual model, and drafting patterns on your drafting views, is that correct? At least in the case of the shingles, the model pattern acts like I would want it to, the shingles are all oriented right on the surface of the roof. That same pattern in a drafting pattern stayed horizontal no matter how I turned the model. At the bottom of this message is the same pattern that I did the same thing to but it worked out well. On the left a shingle pattern in drafting style, and then modified to a model style pattern.

Something else you could do is invest in Hatchkit. Take it out for a "test drive" from the App Store.

Here's a Mountain Ledge stone Model Pat File from Eldorado that looks similar to what you have in your screenshot.

Change the .txt extension to .pat

You can avoid that unpresentable model stone appearance by adopting a less-precisely modelled stone fill, possibly from one of the sources listed here or by upscaling that fill with our HatchKit Add-In for Revit, available for free from the Revit Store.

The problem arises as a result of Revit extending very short lines to its internally imposed minimum vector length.

BTW our Add-in allows you copy fills within a project and directly manage their type.

Thanks for all the help, the El Dorado patterns are working great for my purposes. I downloaded HatchKit yesterday just prior to posting my question. I'm happy with the El Dorado solution but interested in learning more about how to work with HatchKit. I will look more into learning how to use it.

I have to add that although this was a little frustrating at first, I'm absolutely impressed by Revit. The program does everything that I ever wanted to be able to do as an Architectural Drafter. I have zero knowledge of how to write a program, but it seems like this could be easier. The good news is that there are only a handful of hatch patterns that I would ever use on my elevations so once I have them loaded, I'll be good forever. Great job by the people who are developing this software.
