Hidden Object Display settings in Section + Interior Elevation Viewports

Question

I’ve figured out how to use the main settings in the O.I.P. where you can set obscured objects to display by class (for example show something hidden behind a wall with a dashed line) but I can’t get the override settings when you edit section/elevation in-place to work.

 

I thought these ‘Cut Plane + Display’ settings would allow me to a select a specific obscured object not currently displayed + make it display. Or vice versa take an object that is currently displayed + make it so you don’t see it. So apply the settings to specific individual objects rather than it be done by class.

 

But when I’m in the section/elevation in-place edit mode + I select the object in question + go into the ‘Cut Plane + Display’ settings none of the changes I make there have any effect.

 

The cut plane settings work but the hidden object settings aren’t doing anything for me.

 

Am I doing something wrong?

Be great to hear from someone who uses these settings...

I can't get the Object/Hidden Object beyond/before parameters to have any effect whatsoever.

 

I can get the Cut Plane setting to do what it's meant to do it's just the others do nada.

 

Should be a good feature so annoying not to be able to get it to do anything.

 

How do I draw Matt Panzer's attention to this? Don't know how to mention a user unless they're in the thread already... 

 

Thanks!

Hi Tom,

 

To tag someone start start typing their screen name beginning with "@"

My name would be "@Matt Panzer".

 

To answer your question:  I was beginning to put something together to show you and discovered a bug in the per object overrides for Object Display and Hidden Object Display in section viewports.  The viewport setting work, but not the per object overrides.

I just submitted a bug report for this (VB-177006).

@Matt Panzer thanks on both points

So do you think the per object overrides have ever worked then?

 


Yes.  They definitely worked in 2019.

Thanks @Matt Panzer for sharing this graphic...i am bit closer to understanding these settings but still some confusions.

 

I somehow still can't grasp  what effect has changing 'Hidden Line' to 'Dashed Hidden Line' or visa versa at the top of Object/Hidden Object Display menu under Class name field in section viewport settings.

I actually never use Dashed Hidden Line Render only Hidden Line for sections viewport rendering. Will those settings override viewports background render?

 

Another thing that confuse me is when lets say Hidden line is active for given class in Object/Hidden Object Display menu for viewport will settings in same dialogue for dashed hidden line pen attributes have no effect on result ?

 

I hope you can understand my points as it is quite difficult for me to navigate in somehow overlapping terminology.

 

Thanks.

Hi @drelARCH I feel I understand how these settings should work but agree with you that the results are confusing.

 

For example I have this section viewport:

1328050482_Screenshot2021-03-08at11_52_36.thumb.png.1ee64aa8663458a4a85738e274debe30.png

I have placed an extrude on the outside of the room, before the cut plane. Half of the extrude is visible through an opening in the wall. The other half is obscured by the wall. So what you see through the opening should be governed by the 'Object Display...' settings + the part of the extrude that's behind the wall by the 'Hidden Object Display...' settings.

 

So if I have the Hidden Object display set to a blue line in Hidden Line:

and the Object Display set to a red line + a dashed red line in Dashed Hidden Line:

1253192510_Screenshot2021-03-08at11_52_29.thumb.png.3e1afca78ab5f10fdca0b781bf332370.png

 

I get this:

985569006_Screenshot2021-03-08at11_52_42.thumb.png.1051c3fcb64b893da13b9da875f0f603.png

Which is exactly what I'd expect.

 

But if I don't want to see the red part of the extrude through the doorway in Dashed Hidden Line + I change the Object Display settings to Hidden Line:

I get this:

1315886031_Screenshot2021-03-08at11_52_47.thumb.png.d49b04f3a0ad0b5ca8fb4620711424bb.png

 

I lose the dashed line representing the back edge of the extrude which is what I'd expect to happen but I also lose part of the hidden object geometry, the vertical blue line representing the front edge of the extrude. Why has this happened? Why would the settings governing the Object Display impact on the hidden object display??? Is this another bug @Matt Panzer?

That setting is how you want to render each object in that class unto itself.  In most cases, you probably only want to see the object as rendered in Hidden Line so you see only visible edges facing the cut plane.  Dashed Hidden Line will show the back faces (hidden edges) of each object in that class.

When the "Display" setting is not set to "None" the setting will override the Background Render setting (if different). However, if the background Render is "Dashed Hidden Line" the dashed pen attributes of the render mode will be used.

The only difference the Background Render setting will make is that setting it to "Dashed Hidden Line" will cause the hidden edges of objects and hidden objects beyond the cut to use the dash line attributes defined in the render settings.  Typically, you would want to use a Render Background of "Hidden Line" because these Object/Hidden Object Display settings provide much more control.

I agree about the terminology confusion.  It stems from the existing "Hidden Line" vs "Dashed Hidden Line" terms.  As you know, "Hidden Line" render means the back face edges are not shown and "Dashed Hidden Line" means they are shown.  The terminology is not explicit enough in stating to "show" or "not show" these edges.  It's not that hard to grasp when you have them as just two settings for a viewport render mode, but expanding it like we have has compounded the problem.

This issue is related to a known bug.  The vertical blue line (as you say) should show.

Ok thanks @Matt Panzer 

Just out of interest, is there a way for someone like me to check the status of bug reports? 

This for example was a bug filed on my behalf last August: 

Occasionally I remember about it + wonder whether anything's happened with it...

I don't believe there's a way for you to check the status aside from asking a VW employee.  I took a look and all I can tell you is that it's priority level is set to "Major".  However, I cannot tell you when you might see the issue addressed.
