Hello all,
In the previous C3D 2012 version I was able to set surface transparency just setting it on a layer with defined transparency. Example: I set my "existing ground" surface to a created "EG" layer (example name) and set transparency layer to 50% (example, again) and it WORKS! My surface become transparent...
But now, in the C3D 2013, I can't get the same results... my surface is not getting transparent. I already tried to turn off/on hardware acceleration and adaptive degradation and show/hide transparency.
More details: I can get transparency on points, triangles, contours etc... but not on elevation, and this is my priority.
Thanks very much and sorry for my bad english,
Solved! Go to Solution.
I am having the same problem. Exact drawing that worked in 2012 does not in 2013. Looks like they broke it.
Hello Schlagel
Yes, apparently they broke it:
"Thank you for choosing Autodesk Support. I was able to confirm the issue you reported to us and to see how it worked on 2012 version. So, your case has been documented and sent to our development team for investigation. The development team will try to reproduce your case and make an initial assessment. We appreciate your patience as we work to resolve your inquiry. "
It was april/12 and I still don't have an answer... Lets push to see if they solve it.
Hi!
I am working in Civil 3D 2012 and I can not get my surface transparency..
I have done elevation analysis and I want to see some object under surface. Please can You explain it step by step how to get it?
Thank for any help 🙂
Try to set surface layer transparency (more then 0 of course) in layer properties manager and check if:
- the "Show/Hide Transparency" is enabled
- hardware acceleration is on
Hope it works.
I do not know why it is not working, and make new layer with transaprency and make it surface layer.
In some atricle I have read that I need in drawing settings for object layer choose some transparency layer an I did that too..but still nothnig is happening..
I am not very computer guy, so maybe one silly question..where I can see hardware acceleration and for what it is?
Thank You both for quick replay 🙂
I show in the picure:
- Transparency control in the left red circle;
- Acceleration hardware in the right red circle.
What can't you turn on?
Transparency control, hardware acceleration or surface transparency?
I guess it can be hardware problem... what is your graphic card and PC configuration?
Sorry, yeah, the transparency is in the layer not the suface. Too early to think clearly apparently.
Also, once you get it working, to plot, make sure "plot transparency" is checked in the plot dialog...
My graphics card : Intel (R) Graphics Media Accelerator HD
Processor: Intel (R) Core (TM) i5 CPU 650@3.20 GHz 3.33 GHz
I think you might need to get a dedicated graphics card, especially when working with surfaces and such...

I've tried this in 2012 - Created an EG on Surface named C-SURFACES-EG and set Transparency to 50% - works as expected.
Tried Plot preview and turned on Transparency - Plot previews as expected
Tried in 2013 and no transparency is honoured although plain CAD hatches transparencies are honoured.
Lets see them rush out a fix for this......NOT How can this one have missed the quality control prior to releasing 2013??

Thanks Diegoal an JonRusk for helping 🙂
I know I need better graphics card, but I did not think that is problem because it is not shows transparency, because does not seem to me "bigger" job for card then doing elevation analysis which I could do?
I will try it tomorrow on better computer and I hope it will work 🙂

The problem is that you don't have a graphics card to begin with. Integrated graphics chips are not very good and have to share the system's RAM. It won't matter the job size, sometimes the integrated graphics chips just won't do things like hardware acceleration and display items correctly. That's why you'll mostly get responses to get a dedicated video card.

Further to my previous post, Autodesk have confirmed that they broke this in the 2013 release...
"Thanks for your reply and for supplying the drawing file. I confirm this is an issue with the 2013 release of Civil 3D.
I have documented the problem and submitted the file to the development team for them to look at the issue more closely.
One workaround that can be used for the time being is to switch to the "Wireframe" visual style, which will honor layer transparency settings. However this is only applicable to the viewport and the transparency will still not be honored when plotting.
For the plotting we don't have a workaround for the time being."

If you are effectively trying to fade the surface back, a possible workaround could be to draworder the surface to the back, put a hatch on top of it with a transparency and with a color that prints at 0% screening. It's not the same thing as a transparency but close.
