Model vs Drafting pattern in sloping surface

I have drawn a sloping ceiling with a pattern.  I have used this identical ceiling family before in this way.    Not (r19) the sloping surface renders fine with a DRAFTING hatch pattern   https://drive.google.com/open?id=1fny5JPZUyUSOzUwoFb0cBV2TY_QAPnia&authuser=steve@designbuildllc.com...

 

...but at an unintentional angle when using the same material with a MODEL pattern.  https://drive.google.com/open?id=1fmnpMKW_2XLc1i5XepjxqbYwGJU09CVH&authuser=steve@designbuildllc.com...

 

I have tried other model patterns with orthogonal patterns, even created a new one... all skewed like this. 

 

the ceiling family has all sides at 90d to each other.

How to correct?

When you write ceiling family does that mean a family built in the family editor or one using the Ceiling tool?

 

Generally a Drafting Pattern is intended for 2D representation because it does not scale, in the same way that we used to apply a sticky back pattern from the art supply store in the old days of drafting. The patterns are defined according to a printed size, not a real world dimension like 24x48 ceiling tiles for example.

 

Model Patterns do scale in views and attempt to respect a 3D view's vanishing point, appearing to get closer and closer together the further into the distance the view they are drawn.

I've used model patterns before as patterns for ceilings, with no problems.  Are you seeing my problem - model patterns are displaying at random angles.   like this...  https://drive.google.com/open?id=1g2JpgZBOYutTsHNrxVRVBNUTuEQcophu&authuser=steve@designbuildllc.com...

 

I only used DRAFTING patterns as a work around, they displayed at 90d angles to the model.   MODEL PATTERNS display at unpredictable irregular angles.

Well... I just did some testing in 2018.3 and a ceiling created using Sketch Ceiling AND assigning one side to Defines Slope before finishing the sketch is creating a result where the pattern is rotated arbitrarily.

 

If I create the ceiling and finish sketch first the pattern is oriented correctly. Then using edit to define a slope it does not alter the orientation.

 

That's weird...

you should be able to tab into the pattern and rotate it to be the angle you want.  You can also use the align tool.

You miss the subtlety I'm writing about... I'm slightly familiar with the basics 🙂
