AutoCAD Civil 3D :: Surface Transparency Does Not Work In 2013

Jun 22, 2012

this thread confirms that Autodesk broke the surface transparency functionality in 2013. I imagine by the lack of response to the original thread that this is either a little used or not well published feature....

AutoCAD Civil 3D :: Surface Analysis And Transparency

Nov 6, 2013

It appears color transparency for surface analysis is now broke in 2013.  It used to work in 2011 because I use to bring in Lidar data and run elevation analysis over top of aerial photos. I never found any type of resolution.  Is Autodesk aware and are they working on this?

This issue reminds me of the Point Cloud issue with Lidar data right after 2013 came out.  It worked in 2011 just fine and then 2013 they broke it.  After calls to autodesk support and thread exchanges plus several months of waiting, service pack 2 for 2013 fixed the lidar classification issue.

AutoCAD Civil 3D :: Surface Transparency (elevation)

Apr 17, 2012

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.

AutoCAD Civil 3D :: How To Create A No Work Zone On A Surface

Mar 6, 2012

I use RocTek for cut/fil calculations, but the program is old and basic, I'm trying to transition to Civil 3D 2012 right now. Typically I create "no work zones" around my building footprints, so that I can do a more detailed take-off in those areas for over-excavations and that sort of thing. Right now I'm using Civil 3D to create an existing surface, a proposed surface, and then a volume from between the two. I thought if I just traced my proposed contours over the existing within the building footprint that I would get what I was looking for. However, analysis of the cut/fill volume shows that there are still some changes being made around the edges of the building.

Is there a specific way to make a proposed surface, but leave parts of the existing surface untouched?

See attached photo. The upper middle portion of the screen is where the building is (forgot to turn on layer).

AutoCAD Civil 3D :: Surface Clipboard Copy - Paste Does Not Work Fine

Mar 20, 2013

You can copy both the surface and the original (in this case contour polylines) data or only the surface. In both cases paste operation results into a copy of both data and surface.

Ok, But when paste and rebuild, the distance from original base point and destination point is applied in turn to the surface itself. Maybe it is a BUG ?

AutoCAD Civil 3D :: 2013 Pipe Networks Reference Surface Amended

Sep 9, 2013

I have designed a pipe network in Civil 3D 2013, first I created a rule set for both structures and pipes, then I created a parts list, next I built my network.

Where more than two pipes connected to one structure, I found 'applyrules' couldn't align everything appropriately, so I had to manually amend the levels in 3D to ensure the pipes connected correctly (soffit to soffit / top invert to top invert).

My problem is that after doing all this, the surface model has been amended! I have changed the reference surface in the network properties and in the vista. The rim height of my structures seems to have been adjusted in the most part but my pipes have not.

In areas where the surface has gone down, my minimum cover is violated. Is there a way to move the pipes back down to minimum cover, without using 'applyrules', as using that command would change the gradients to the minimum, some gradients have changed during my manual adjustments.
 
Furthermore, where the surface model has reduced in level significantly, my pipes are now above the surface and the manhole has stayed there too.

AutoCAD Inventor :: Create Work Axis Where Work Plane Intersects Curved Surface?

Sep 9, 2013

I keep running into a situation where I would like to be able to create an edge or a work axis at the intersection of a work plane and the surface of the part.  I figured out a work around if the surface is flat, but I haven't figured out a work around for a curved surface.

How do I create work axis where work plane intersects curved surface?

Or put another way: How do I project intersection of work plane and curved surface onto the work plane in a 2D sketch?

I need to be able to draw a 2D sketch on the work plane, but get a perfectly matching projected line onto the work plane, from the curved surface, at the intersection of the curved surface and the work plane.

The attached jpg shows the intersection in question.  I circled it.

AutoCAD Civil 3D :: 2013 - Dynamic Surface Profiles Acting As Static Profiles

Nov 14, 2012

I am having some issues with surface profiles on a dreffed alignment no updating dynamically.

Currently it requires me to set them to static, then back to dynamic and they update.

I am well aware of the issue of dreffed surface profiles staying static. I am using the work around of dreffing in the surface and sampling in the drawing using the dreffed alignment.

AutoCAD Civil 3D :: How To Correct / Manipulate Surface To Show Proper Flat Surface

Dec 2, 2011

I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.

The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.

How to correct/manipulate the surface to show a proper flat surface?

AutoCAD Civil 3D :: Reduced Maximum Length For Surface Triangles Causes Surface Holes

Oct 22, 2012

Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.

I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.

AutoCAD Civil 3D :: Editing Existing Surface Using Edit Surface Command

Nov 14, 2012

I am trying to add points into a surface. I have done this before without any problems, but now I am having issues.

When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.

I select the surface and use the 'edit surface command' in the ribbon, choosing add point. 

When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!

Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.

What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?

how do I shrink labels? Where is it in the settings ; the Align folder had been check.

AutoCAD Civil 3D :: Add A Surface To Blank Drawing / Then Upload DEM Files To Surface

I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.

The surface imports correcty, but when I try to import  points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.

AutoCAD Civil 3D :: Import Surface Into Revit To Merge Surface And Buildings Together?

Jul 29, 2013

I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.

The questions:

Would it be better to import the surface into Revit to merge surface and buildings together?

Would it be better to import the buildings into C3D to merge entities?

Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?

AutoCAD Civil 3D :: Creating Subset Surface From Main Surface

Sep 15, 2013

I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.

i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline.  This seemed to work, but  when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.

AutoCAD Civil 3D :: Create Cut Fill Surface From Existing Surface

Mar 1, 2013

Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.

The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.

I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.

1. Novapoint is quite unstable and crashes alot

2. You cant create profiles out of 3d faces

3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface

4. A large surface made out of 3d-faces demands alot of computer power 

So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.

AutoCAD Civil 3D :: Trim Surface To Another Surface

May 3, 2013

I was wondering if there is an easy way to trim one surface to another.  Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge.  Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.

If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?

AutoCAD Inventor :: How To Delete A Work Surface

How to delete a work surface.  These work surfaces were imported from an iges file which contains thousands of work surfaces.  They are not associated with a part feature which can be deleted.  I've developed a routine to sort through these and identify unwanted work surfaces based on their positions.  The best I've been able to come up with is to make them invisible, but I'd really like to delete them completely to clean up the file.  I did try to loop through and delete any surface body objects associated with the work surface but that failed.

GIMP :: Layer Transparency Does Not Work

Aug 15, 2012

I find myself creating new layers and making them slightly transparent all the time. But when I do this using Gimp it does not work right? This is what I am doing:

Add new layer

use transparency/opaque slider to change the setting

what happens is that the new layer stays solid until it goes below 50% on the slider and then it disappears, above 50% and it is back. It is like the 50% mark is an on/off switch for the layer.
