AutoCAD Civil 3D

[#1]

I do not know why but I can not turn it on...

You think that is problem of my drawing?

[#2]

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?

[#3]

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.
