View Full Version : 2012 Adding shading (or hatching) to a ceiling

Help! I have several types of 2x4 ceilings and I want to disguish between them graphically by shading or hatching. I want to bury the graphics in the compound ceiling definition so I don't have to visit every ceiling on the project to apply the hatch. I have tried everything I can think of with no luck. Am I missing something?

Have you tried creating the ceiling plus desired hatch pattern with Hatch22? I recently tried out the program and was surprised at how easy it was to create difficult hatch patterns with it. I haven't tried what you are describing but I don't see why it wouldn't work.

Two thoughts:
1) Consistent color shading mode. You could give each ceiling a different material and then when you needed to distinguish, use consistent color mode.
2) Edit the hatch patterns (even if you don't want to use Hatch22): Simply copy the code for other hatches into the 2x4 .pat file. Here's a sample:

*CEILING_TILE,Ceiling tile with sand pattern
;%TYPE=MODEL
0, 0,0, 0,24, 48,0
90, 0,0, 0,48, 48,0

37.5, 0,0, 1.123,1.567, 0,-1.52,0,-1.7,0,-1.625
7.5, 0,0, 2.123,2.567, 0,-.82,0,-1.37,0,-.525
-32.5, -1.23,0, 2.6234,1.678, 0,-.5,0,-1.8,0,-2.35
-42.5, -1.23,0, 1.6234,2.678, 0,-.25,0,-1.18,0,-1.35


The first two lines are the name, then next two lines are the 2x4 grid, then the last four lines are a sand pattern. Just swap out the last four lines with any other hatch pattern you find in a pat file you like.

I cut and paste the text into a file. I keep getting "no model type patterns found" I compared it to other patterns and it looks correct. Any ideas?

Check out the first two lines:

*CEILING_TILE,Ceiling tile with sand pattern
;%TYPE=MODEL

The first line has to be *name,description where name has no spaces or special characters.
The second line has to be exactly as shown.

I got it to work by following your example. I copied the 2x4 pattern from the Revit master, then I found a good ceiling texture on the web. I cut from that and pasted it into the 2x4 and renamed it.

Success! What prompted this crisis (The project is due at noon today) is that I could not get coarse fill pattern to show on ceilings. Still can't, but I think this is a better solution anyway.

Thanks.

This worked:

*Ceiling 24x48 textured, 24 x 48 Tiles
;%TYPE=MODEL
0, 0, 0, 0, 24
90, 0, 0, 0, 48

0, 0, 0, 2, 2, 0, -4, 0, -4, 0, -5, 0, -4, 0, -3.5, 0, -8
120, 4, 2, 2, 2, 0, -3.5, 0, -3.5, 0, -5, 0, -4.5, 0, -3.5, 0, -8
240, 2.5, 4, 2, 2, 0, -4, 0, -4, 0, -5, 0, -4, 0, -2, 0, -3

This was a very good lesson: That I can combine textures. I will definitely remember that.

If you needed to use the same material(same type of ceilings) you can easily do that with filters

It looks like this:

I create lots of ceiling (and floor) patterns using this method....What I wish is we could have the ability to have different levels of a fill pattern, so if I wanted to fade or change the color of one fill so that the primary pattern stands out in front of the other.

One method of making this work though is the hatch22 add-in and making the grid be gapped so that it's thicker than the other lines.

Mike, glad it worked out! I just started using this method when I was asked to show CMU as a combo of diagonal crosshatch and concrete hatches. First time I've ever needed it and this was the solution I found. Cheers!

What if the lines making the 2' and 4' rectangles are doubled, with a tiny gap between them? Wouldn't that have the effect of making them heavier in weight?
