Visual Style Transparency issue

[Daniel.Chr]

A small but annoying issue I have found when I switched from Inventor 2016 to 2018. I work in the Technical Illustration visual style and in 2016 when I put a glass appearance on a part, it will be transparent. However in 2018 this no longer happens, unless I use a section view. I have tried various materials and appearances but I cannot regain this functionality, and it is becoming somewhat annoying as I am going through assemblies checking items. Does anyone have any ideas? I have attached two screen snips below, the blue and white panels have material set as clear glass and appearance is clear blue and clear.

Hi! Could you check the following option and see if it works better?

Tools -> Application Options -> Display -> Settings -> go to the bottom -> "Enhance Appearance Transparency" -> check the option.

Does it work better now?

Many thanks!

[Daniel.Chr]

I already tried that, it has no effect on this issue.

Hi Daniel,

Then we will need to see the files. Could you share the files here?

Many thanks!

[Daniel.Chr]

It is an assembly of parts based off derived component sketches. Do you know a way to bind/compress them down to a remove the dependencies?

Edit: It seems that Technical Illustration mode is having issues with making anything transparent/semi transparent. When activating a part in an assembly to edit it still renders inactive parts completely, even though they are set to 25% opacity.

Hi! I am sorry I am not sure if I understood the request. If you want to cut the associativity between the derive sketch and it source, you can right-click on the derive node in the browser -> Break link. But, once the associativity is broken, it cannot be recovered. Is this what you are looking for?

Many thanks!

[Daniel.Chr]

That sounds like what I was looking for but since that will break the current job files I will have to throw together something else to upload. I should have time to do that tomorrow.

Any Resolution to this one?

[johnsonshiue]

Hi! Do you mind elaborating the issue here or starting a new thread? Your issue may not be the same as the original posting.

Many thanks!

Hello, i think this is the same issue.

[karl.lednik]

I've noticed this as well.  If I set a part to be transparent;

and switch to Technical Illustration view style, the part turns either dark gray and opaque;

or light gray and semi-transparent with no edges shown behind the transparent object;

 Sorry, the post editor is being really odd.

@karl.lednik  I think thats just a "limitation" of the Technical Illustration Visual style.. 

@johnsonshiue Or maybe its a bug..

[Daniel.Chr]

Unfortunately I don't think I can help on this issue anymore, shortly after my last post things changed around at my company and I got shifted out of drafting. I no longer have older versions of Inventor available to me to showcase the difference. What I recall is in 2016 if a part appearance was set as a transparent type (ie Blue - Glazing), in technicolor mode that part would operate similar to the shaded with hidden edges view mode (sans shading, just a flat hue but transparent with lines). In 2018 it no longer operated this way and appeared as a solid object, it is this way in 2019 as well.

Hi Guys,

It does look like a bug to me. I cannot explain the behavior. I will work with the project team to understand it better.

Many thanks!

@Daniel.Chr ,

Thanks for reporting! 

It is a known limitation that transparency under technical illustration is not supported in Inventor.

We support in Inventor 2016 when the technical illustration first introduced into Inventor, but at that time, the transparency effect is not good enough and flickers heavily when rotate/zoom or doing other graphics operations.

So the transparency has been disabled for technical illustration from Inventor 2017.

And since that, there's no user reporting this issue to us until we received your case. Thanks for letting us know your case! We are going to track a bug internally and investigate whether we can find some new solution to enhance this visual style. 

Before we coming up a solution, would you mind using non technical illustration visual style for transparent effect? 

Thanks,

I do when I have to view the transparency. I prefer working in technical illustration as there is no lighting/shadows to alter the view (I can see everything without have to rotate to adjust lighting/etc).

[KMK-Consulting-Engineers]

Also, i have just been looking at HALF SECTION VIEW.  That seems to be completely ignored by Tech. Illus. Though it does draw a nice line where the section should be.

It does produce the quickest, cleanest, images for use in documents, so full funcionality would be very useful.

Unless i'm using the wrong program to produce these Images??

Hello,

so you are able to render basic reflections and lighting (shaded view) with transparet objects, but are unable to do the same with simple unicolor textures without lighting?

Hello,

still not working!

I have the version Inventor professional 2024.1.1 and still not possible to use the transparency with Technical illustration visual style. 

are any plan to fix that?

Thanks in advance!
