Missing Portions of Vectorial 3D Hatching

Anonymous

Using Ac10, I have two Elevation views that have portions of Vectorial 3D Hatching missing. Any Help would be appreciated.

Jay, does it make a difference if you substitute a different fill?
Scott, I had hoped your idea would work. It was a good idea, but did not work for this problem.

Why don't you upload a module of the problem area?

Cheers,

Tried to create modules by floor level. Each of the Module files is larger than allowed. Zipped they are small, but the zip is not an allowed extension.

I am guessing that the balustrade with the spheres on to is all one object?
If so try deleting it temporarily (or move it to a layer that is turned off) and then regenerate the elevation.

I have had this problem with 3D objects that sit in front of walls or other objects with a hatch pattern in the material of the surface.
That surface sometimes becomes invisible.
It has something to do with the way the object is scripted and appeared to be a problem when V10 arrived - never had it before that.

I had to re-script some of our objects to use grouping i.e. group the sphere and gropu the post, add the groups together and display the result.

I found if you select the wall you will see a bunch of lines radiating from the sphere that has something to do with the way the hatch fill is generated around the sphere. Zoom in close and you may see the perimeter of the fill crossing over on itself (self intersecting) which messes things up and the fill (and hence the wall) does not display.

I think I may have posted something here before - I'll see if I can find it.

Should be allowed. If you still want to upload it. May be time to upgrade to 12 mate.

This is the only related post I can find.

The other I was thinking of must have been something I sent GS.
I'll see if I can dig anything up but it was quite some time ago.

I can't find any of the old information.
But I have managed to create a few images that explain what I think is the problem.
It is very intermittent and depends on the position of the objects.
I couldn't replicate the problem but these images will show what I mean about the fill possibly becoming corrupted (self intersecting).

The first is simply a sink and tap in front a wall that has a hatch pattern (just a light dotted hatch).
The selection shows how the elevation creates a fill out of the hatch with a hole cut around the sink and tap.

The second image is zoomed in on the top of the tap that has a spherical top.
Notice how the perimeter zigs in and out of the facets on the sphere.
I think this is what can cause the problem.

The third image is zoomed in on the top of the tap again but the tap has been re-scripted to use grouping to merger the handle, spherical top and the rest of the tap.

The perimeter of the polygon still goes into the facets but not as severely.
This hopefully stops the perimeter self intersecting and eliminating the problem.
At least it has solved the problem for me as I have not had any trouble since changing the scripts.

As I mentioned before it is very intermittent and depends on the position of the object in front of the hatch.
Sometimes just moving the object forwards, backwards or sideways can stop the problem.

Actually the railing is a combination of three part. (Railing Vertical 10, Column & Sphere 10).

We have the winner!

Decided to remove the Sphere object and model the tops of the rail posts with a combination of column and (3) Pyramid 10 with SEO. Kind of elaboraite solution. Any other Ideas out there?
