Basic Roof family cuts correctly in section but not in plan

[ryan.hodgeY6J4Q]

I have made a set of single material stone roofs. They are basically a single variable stone material with modified sub elements for falls. For some reason, they cut correctly in any sectional view, displaying the stone materials, but in plan they just show as white. Not related to template or graphic overides as far as i can see. Phase filter doesnt do it. 

In a 3d view i can get it to display correctly in section and incorrectly in plan depending on the selection box position. 

No idea what it is. A bug?

 Sounds like Coarse Scale Fill Pattern.  Change the Detail Level to Medium or Fine.

Thanks for the reply, but don't think its that. The view was already set to fine, is there anything else it could be?

You are talking about Plan VIEW; right? 

FWIW: Here's a list of 33 that you can reference to help you troubleshoot in this instance:

There are several things that could be the culprit. Phase/Phase Filter, Discipline, etc. 

Post your RVT here.

Afraid cant post it, as commercially sensitive. 

RE your earlier comment, this is regarding any view i choose showing the object. The section views display the material cut. The Plan cut views show it white. The screenshots are from a 3d view, where all i changed was the selection box. As soon as the element cuts in plan it looses its 'hatch'

If you can't post your RVT, then provide the steps to reproduce the issue.

I've recreated the issue in a separate file. 

This a fresh project. I seem to have localised the issue to when the section box/or plan view cuts the roof geometry the cut pattern defaults to the 'shading' pattern under object styles 'roof' (as opposed to the 'cut pattern'). I have no idea why it does this. Deleting the 'default roof' under object styles>material causes the shading to revert to a grey colour which doesn't appear to be defined by the material of the element. 

If I change roof object style to the material I desire it gives me the appearance I want for this section of roof, however affects all other roofs too, so not a good solve.

Create Parts and Show Parts.

The sample is using the shaded display mode which uses the settings in the graphics tab of the material. You don't have a surface pattern applied to the material, only a pattern for when it is cut:

Also note: since that is a roof you will probably only see materials on the edges when you are cutting it or when you are using the render display style. Roofs can be funny like that.

Lower your View Range Cut Plane.

Thanks this solved it. Feels more like a work around but solved the cutting in plan issue.
