Clipping plane filling in with the obj jpg in V8

Hi,
V8
in V5 the clipping plane looked like a slice through the object, as it should.
In V8 its using the obj jpg to fill in the area AROUND THE slice as well as across the slice itself.

Whilst copy paste has brought in the obj with its mapped image, looking good, and I am able to at last work on it, after the problems of a dogs breakfast with file import.
Clipping plane is doing this .

I havent moved it, its as it came in from V5.

IMPORTANTLY…even the file open and browse to the V5 file method, that displays the obj correctly, it also shows this incorrect section effect ! :rage:

How to solve this one ? Hi McNeel you have this file of mine please examine and see this issue.
whats the fix ?

has V8 other issues I have yet to discover ?

Steve

what is the file name, so that I can have a look? Did you upload it via the file uploader? Otherwise I don’t think I can access it.

Hi,
It was uploaded via the upload link a few weeks ago, .3dm and the three obj and jpg.

Wim might be able to help, as he found it for someone the other day.
the V5 file name is
RAF Type C Mk III EK NsideFrontBrakeAssy_RhinoV5 1to1InchDec template v4.3dm

and the V8 will start with that and then suffix say v5into v8 or something like that !

the obj that this problem is on is
OBJ M 2.2.0 TypeC MkIII EK NsideFrontBrakeAssyV3PSCAN allALIGN high2.9Kp6colvert
on layer
NO RULER V2 OBJ M 2.2.0 TypeC MkIII EK NsideFrontBrakeAssyV3PSCAN allALIGN high2.9Kp6colvert

That should find it.

Steve

I found the file, thanks.
I do see sometimes the issue that the fill is drawn even when I deliberately tell it not to. I’m still poking to see what is going on there.

I can’t find a workaround for this issue. It seems indeed Rhino 5 is doing a better job here. If this gets fixed soon I’ll send you a link to a build to test.

RH-86700 Clipping plane shows fills when it shouldn’t

Hi Steve -

When I copy-paste the mesh and the clipping plane from your model in inches to a default template in millimeter, that area around the slice is no longer filled. In your file, tightening the tolerance and moving the clipping plane back and forth to force a redraw also fixes that.

As for using the texture as fill, that is the default setting for clipping sections. You can change that from “Viewport” to, e.g., “None” in the section style:

… or use “Solid” as the pattern instead of “None” as it is set to now.

Note that your mesh gets flagged as a bad mesh when running MeshRepair on it. Also, running SelClosedmesh will select that mesh, eventhough it’s very clearly supposed to be an open mesh. Rhino 5 didn’t have the option to fill sections on open objects when the section itself is closed. This option is available in Rhino 8 and is on by default. Because this mesh says it’s a closed object, turning that off doesn’t have an effect in this case.

To have this work as in Rhino 5 for this mesh, you can change the Rendered display mode to not use section styles and turn off Show fills:

Hi
@wim
where is section styles, have wandererd my Mk 1 eyeball up and down prioperties cant find it.
if using the obj jpg as a fill is considered default worthy, someone has different ideals than me.

Steve

Hi,
Just where is Section Styles PLEASE.
as staring at this is awful.

cheers

Steve

Hi Steve -

By default, the section style is gotten from the layer property:

You can override this on an object:

-wim

Hi,
V8
not sure what setting to change mine match, except render, change that and the texture is lost so cant be that.


Steve

Hi Steve -

You change the section style:

-wim

Hi,
@wim
but my printscreen shows I had Section Style set to ’ By Layer’ .

yours is By Layer,
mine is ‘by layer’

and should this not be set by default to whatever it should be, so it doesnt do this, it never did so in V5.
we shouldnt have to spend time altering things back to what worked.

Steve

Hi Steve -

As you say, that’s your printscreen. Since you posted that, I assumed that you wanted to control the property on the object instead of on the layer. That’s something that you can do, as I pointed out earlier:

Personally, I would keep this property “By Layer” and then change that from the Layers panel:
