Insulation hatches in walls.

[j_starko]

I've read thru a bunch of previous posts dealing with hatch patterns for insulation patterns in a wall assembly.

I don't want the curvy "s" shaped lines of the batt insulation, I'd like the pattern to be a series of lines , staggered, and perpendiculat to the edge boundry lines of the insulation.

I'd like my end results to look as follows.

the upper portion of that wall is the revit generated hatch..
the lower part is one that I created using a repeating detail . It has to be added in each view that the insualtion areas are being detailed.

What I was hoping is that there is a fill pattern that could work for the whole project. so that every place that there is a a section of the wall , it would show the pattern I 'd like ( the horizontal lines) and not the cross hatched pattern.

Any tips ?

What if you split the wall layer and use these two different materials? You will have to create the insulation material you want but that's easy.

OR,

If you are not cutting through windows or doors you could try the trick of embedding a small sweep to your wall assembly. The sweep is formed by a profile family and the profile family has the detail you want.

It is not the best solution because if your wall changes in height, you have to edit the profile to adjust the modification, but you can be inspired bu reading this thread:

I would still try the first suggestion, though.

Hey Thanks , I had just created that wall really quick to show the two hatch patterns I was talking about.,


I want the wall to look like the lower one, all the way thru the wall and in every detail.

Where i'm having troubles is making the insulation hatch work.


I may be wrong the underlying therory for wall material hatches. I was under the understanding that it just takes a .pat file or a simple parallel line or crosshatch wall pattern .

I just want it to have the final out put too look like the wall section i've drawn with those staggerd, offset line segments. not the cross hatch.

I wish the batt insulation tool could be modified to also be a "rigid" insulation tool.

I think that all you need to do is find, or create the hatch pattern that you want. You can't create it in revit, but there are programs out there that will create custom hatch patterns, just do a search for them.
You can then use that hatch pattern for your wall material fills, so if you have a stud layer that has insulation in it you would make that layer in your wall type have the insulation fill pattern. The downside to this is that you can't control where the insulation starts or stops, the whole material will get the fill. However, once you have the fill pattern created, you can use it as a drafting fill and put it where ever you want.

That's a great suggestion.

I like the 'old school' convention of showing rigid this way too but it's not that simple in Revit (or any CAD package for that matter)
pat files are defined by stops and starts and angles of the lines and they are actual lengths. The problem arises when you define the pat file. It might work for insulation of a particular thickness at a particular scale but it won't flex the way it should if the view sclae changes or the thickness of the insulation increases or decreases.
I gave up on this one a while ago and now just use a digonal cross hatch instead. The added advantage of a cross hatch is you don't have to worry about the angle of the pattern as your walls change direction. If necessary, I use different grid spacings to distinguish between types 1 and 2.

In the meantime the repeating detail for larger scale views is probably your best bet.

I agree , I've thus far been using a diaganol hatch for the rigid insulation. but the office wants me to make the drawings " .. Look more like autocad" i hate hearing that .. more like autocad .. booo . .autocad should look more like revit. ! haha

so far I've just been using the repeating pattern . It works the best for the detail views.

wasn't sure what the reason for not using just the default insulation that revit has.... or is it just personal preferance....at least its a pat that generally understood.

curious...

[Dimitri Harvalias]

Yup, just personal preference. As I said, this is the way I was taught and how we used to show it in the BC (Before CAD) era. You remember, when we actually drafted... with pencils and stuff. Not all these fancy computers thingies you kids have nowadays! I remember having to draft all my lines, uphill, twenty miles, in the snow....

[j_starko]

haha well said Dimitri ..


althought it sounds like my manual drafting exp pales in comparison to yours ....

The reason I don't want to use the revit default pat files for my insulation is purely what my office wants as their standards. I do like the way the staggerted offset lines look graphically over the default pattern


This should be sortof easy for the Folks at AutoDesk to address.. It could be something similar to the batt insulation tool, it could jsut show the hatched lines instead. I'm gonna mess around with the software developers package. time to take off the drafting cap and put on the programming cap.

You could get the look you want with an electric eraser. Shouldn't take too long...or burn too much in fee.
