Lines showing through

pbacot

I have drawn a roof with rafter tails at the eaves. Now the roof surface, viewed from above, sometimes shows the outline of these tails and other lines although they are not touching the roof surface underside. these other objects are at least an inch below the roof plane-- which otherwise shows a one continuous face. I can see them ghosting through (dotty) at certain angles and zooms but not always, and in every style I try. X-ray is not on. The roof surface is 100% opaque.

Haven't experienced this before and I don't think it was doing this earlier in the modeling. Not sure how it will be with textures or rendering. Any help is appreciated.

Mac OS. SU6 Pro, though I can see the same thing in 7 Pro Demo.

Hi Peter,

SU works this way unfortunately.

Edges are always displayed on screen as 1 pixel. Now when you zoom out far enough that your 1 inch distance is also displayed only through a 1 pixel screen area, SU cannot decide what to display and displays both.

You cannot really do anything about it only

either hide the top edges of the rafters
or export images at a larger size (where that one inch would be on more pixels on image space).
Update: I believe this is what you are talking about:

Here I even "cheated" with the roof as I set it to 5 cm (~2") just the building itself is so huge one cannot see.

As you can see, the farther the roof is, the stronger the effect is (and you cannot even see it on the apse).

The only way I can get around it it to allow a tolerance in such cases or make the offending lines invisible.

Thanks Gaieus and Mike,

Don't know why this hasn't got to me before, but I've been away from modeling for a bit, and perhaps I am adding more detail now. Easy enough to change my technique or the rafters that are (or should be) components. Maybe this should be moved to the Newbie section.

Looking forward to seeing more of your church Gaieus. And what about the other buildings that once were on the same site? Can much be told about those?

Well, these projects are the ones one never finishes - maximum does not work any longer on them.

There will be an exhibition opening next month where some of my older (Medieval) works will serve as "illustration" and this one is actually only the beginning of a large, Antique project.
