Cant see 3D horizon in 2D view

[ceci dip]

Hello, I have added a 3D horizon with the depth of a layer, and i want to see it projected on my 2D SEGY lines, to help my interpretation, according to the manual i should be able to see it 

But is not the case for me: 

These are my elements:

Thank you !

[Paul de Groot]

It is not completely clear to me what your problem is but this is what I think it is. You have a 3D horizon and you want to see the intersection of that 3D horizon on a 2D line in a 2D viewer. That is not supported. You can view the intersection in the 3D scene but not in a 2D viewer because a 2D viewer will only display 2D horizons. 

I hope this helps. Best regards,

Paul.

Hi,

Just to follow up on Paul's reply...

The horizons that may be displayed in the 2D Viewer depend on the type of seismic data selected in the 2D Viewer Launcher window.

Assuming you are in a 'Both 2D & 3D' survey, if you select a 2D line, then you will only be able to view 2D horizons in the 2D Viewer.

All other options allow for viewing only 3D horizons:

But we do have the option to create 2D horizons from 3D by right-clicking on 2D Horizon in the tree:

Then select a 3D horizon and a 2D line that it covers (add suffix) and press OK.

You will now have a 2D horizon at the intersection of the 3D horizon and the 2D line.

This can be displayed on a 2D line in the 2D viewer

I hope this is of some use to you.

Kind regards,

Mark

Hello Mark, 

That was very helpful, I created a 2D horizon from a 3D one and it did exactly what i wanted. 

Thank you !

Thank you Paul for your reply, I used Mark's suggestion to create 2D from 3D and see in in the 2D viewer.

If you can't see 3D objects in the 2D display, what is that example I shared that comes from OpendTect help manual ? 

https://doc.opendtect.org/6.4.0/doc/od_userdoc/Default.htm#getting_started/viewer_2d.htm?Highlight=2D%20viewerhttps://doc.opendtect.org/6.4.0/doc/od_userdoc/Default.htm#getting_started/viewer_2d.htm?Highlight=2D%20viewer

It confused me because it showed 3D horizons in the tree of a 2d viewer, so i thought i was  missing something.

Thanks again for your time.

A 2D viewer (= a flat viewer) can be used to display 2D and 3D seismic. In the case from the user doc we display inline 425 (upper left corner), which tells me this is a line from a 3D volume, hence you can display 3D horizons.

Best regards,

Paul.

I got it! Of course once you pointed it out input in sec not me! It is awesome to be able to see this in 3d and change the z scale so easily. I see that I can contour horizons but not fault surfaces. Is that correct,? Much thanks

That is correct: you cannot display contours on a fault plane but you can display attributes on a fault plane.

Best regards,

Paul.

Thanks. I realized I can convert faults to horizons then import those and contour if I want. I'm working w a big detachment fault that flattens and becomes sub horizontal even reverses dip slightly in places and I think contours would help visualize that surface better.
