OpenGL 3D won’t display models

[Nathan Schwab]

I am having trouble with displaying models within the OpenGL 3D view space. When tin, strings etc. models are added into the view they simply don’t show up. Tins and strings work fine on the other OpenGL view. It’s a bizarre issue because for the first six months of using 12d v15 the OpenGL 3D view worked perfectly fine. I hadn’t changed any settings (at least not to my knowledge) and it is now an issue when loading new or older projects.

I’ve tried logging onto another computer and trying it and it works fine so it doesn’t seem to be a computer hardware issue, more in the realm of a software or setting issue.

Any help would be appreciated.

Hi Nathan

Run this option.
[Project =>Management =>Dongles =>Authorization details]
- Have Outlook, press the Email support button. Then email this to me.
- Don't have Outlook, press the Save to file button and email to me file lic????.zip from the desktop.

Sounds like something has happened on your computer.

Are you saying it works on one pc but not on another?

Do you have multiple monitors? I have seen windows do odd things before where one would be primarily and allow OpenGL but the other monitor has different settings and did not support OpenGL..
You could test that by moving 12d model main app between monitors (have the view maximised)

If you only have the one monitor
Check the output window when you open a project
It should state what OpenGL drivers and settings it opened with...

If you are going through a docking station then those ports for the screens will be different to your computer.

Okay, I've sent that to the support email

Hi Sam, I do have two monitors and gave that a shot but no good unfortunately.

Looking in the Output Window --> OpenGL configuration appears to show no issues as well, all green ticks for me.

Hi Nathan

I have had a look at the file you sent.
It looks like 12d Model is using the graphics card.
There may be an available update for the graphics card drivers.

Have you tried opening the project without your customisation?
Your env.4d file may be based on an old version rather than what is shipped for V15.

If you create a new OpenGL Perspective view, does the same problem still occur?

I will look for the post that lists what to check for.

Here is a post with some things to try/check.

Thanks for having a look Graeme, appears the graphics card drivers are up to date. How would I verify if my env.4d is based on and old version? I've recently updated to the latest 15.0C1r update. How would I open a project without customisation?

I am able to open a OpenGL view as opposed to an OpenGL 3D view and it works perfectly fine. I will have a try and the suggestions in that thread and see what happens.

Thanks again for your help.

You have environment variables that have not been shipped for many years/versions.

How would I open a project without customisation?

I think you are using a desktop shortcut to point to a Z drive env.4d.
You will need to know how 12d Model authorizes and add the relevant info to a copy of the shipped env.4d
or use the env_configs.4d with an environment that points to the shipped env.4d and uses overrides.
There are several webinars on this.

There are two types of OpenGL views. Plan OpenGL and Perspective OpenGL.
Are you saying that the Plan OpenGL view works?
Are you saying that you are not able to create a new Perspective OpenGL view or a new Perspective OpenGL view has the same problem?

Can you open View->View info, the pick your problem view.
You're looking for some "strange" extents.

I'd guess you have some data at 0,0 and some in MGA or similar, or you have some really low z values and some really high as well.

Oh I see what you mean now, the Plan OpenGL also doesn't work. The regular Perspective view is the view that still works with models able to be viewed.

The values look about right for the location of the project.

Fixed! I went into Nvidia Control Panel --> Manage 3D Settings and went to Program Settings --> OpenGL rendering GPU and changed it from the default 'Auto-select' to manually selecting my GPU and it appears to be working now. No idea what might have caused this as I have never had a reason to toggle these settings, perhaps an Nvidia driver update reverted it to default settings if I had to guess.

Thank you to Graeme and everyone else for your assistance.

Well done Nathan.
