Assembly in drawing undesired transparant

[w.poortinga]

Hi,

I have a simple assembly looking like this:

However, when putting it in a drawing, it looks like this:

What can I do about this? I don't want the  model to be transparant in my drawing.

EDIT: I'm using the Warm light lighting style in my assembly. When I switch to One light or Two lights the model becomes transparant in my assembly too. So I guess the drawing takes one of those lighting styles by default.

Is there any way I can make my model non-transparant for in every lighting style?

Hello,

Have you gone into the browser and checked that transparency is turned off?

If that doesn't work, could you share the files on here?

What version of Inventor?

Have you installed all Updates?

Can you zip and then Attach your project here?

I feel like its a visual bug/problem. I did check transparency but that's not the problem.

FYI; the first picture is with transparency on, the second with transparency off:

Like I said in my first post this problem also persists in the assembly itself (with one light / two lights lightning styles). 

The first picture is with Warm Light on (it's fine there); the second is with Two Lights:

So I guess Inventor uses One light or Two lights as the lightning style for drawing views?

I'm using Inventor 2019 with the latest updates installed.

I cannot upload the part right now, I'll do so later if no one has a clue what can cause this.
Thanks in advance!

I have seen at least one other report of this issue, but to my knowledge - no one has posted a dataset for the purpose of actually diagnosing the issue.

Hi! Indeed, if you could share the files here, we can try to reproduce it and understand the behavior better. The only logical reason I can think of is the components are set to transparent. If they are not, we may have a bug here.

Many thanks!

I added an .ipt as an attachment. FYI: I don't have this problem with every material.

If you open your Appearance Browser - are you showing an issues?  (The symbol ! in yellow triangle.)

[w.poortinga]

Thanks for your reply. No I don't see any errors/isseus.

I also didn't apply any appearance overrides by the way.

Did you manage to reproduce the transparency error?

I still only get this transparency with the One light and Two light lightning scenes. Unfortunately one of these is used for drawing views.

Did anyone manage to reproduce the bug/error/x I had with parts appearing transparant?

[johnsonshiue]

Hi! I am able to see the behavior. It does not look right to me. It seems that the appearance style has a weird transparency attached to it. I cannot explain the behavior. I will work with the project team and understand it better.

Many thanks!

[w.poortinga]

Thanks for taking the time to investigate this.

Hello @w.poortinga,

Thanks Johnson who passed it to me! 

With more investigation, it is a problem when appearance "teak-***" work with lighting style one light/two lights. 

The workaround is switching to other lighting styles other than one light and two lights.

By the way, ticket INVGEN-23062 is filed to follow up the problem.

Hope it helps!

Thanks for coming back with your reply 🙂 

I can change the lighting style in my assembly, however I can't change the lighting style of my shaded view in the drawing (which is where the transparency actually bothers me).

I found a thread mentioning changing the default lighting style in lighting.xml but I can't even find the word 'default' in there.

Is there any other way to change it?

Hello @w.poortinga,

Thank you for the clarification and unfortunately, the drawing shaded view is default to "Two lights" lighting style only.

It seems no better solution here, please stay tuned for a fix for the ticket.

if you really want the shaded view, please select other wood texture for an alternative solution.

Hope it helps!
