I am trying to use a selected surface in a LISP program. I want to be able to save the currently selected surface into a varialble that I can use to control the style of the surface. I would be either selecting the surface by picking the surface from the drawing, or selecting the surface from the list/dialog box of available surfaces. I can't seem to locate a system varialble that holds that info.

I have included some surfaces as run off's but when automatic is select - my chosen surfaces are ignored & a mishmash of surfaces result - can the auto run off feature be edited?

View 2 Replies View RelatedI 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?
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.
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!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
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.
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.
Is there any way to change the referenced surface on a Surface Elevation Label. I can see the surface in the properties but cannot change it.

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?
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.
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.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?

My problem added with pic ... I want to make volume calculate for sample road project. When I try to compute materials I cant use Corridor surface for DATUM... There is only target surface on option..
View 2 Replies View RelatedI am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
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?
I have some illustrator artwork and I want to save different elements on the artwork as new files but without saving the whole artboard? I can't seem to find a simple way to do this? I have tried copying the selection, opening a new document and pasting but I still have to then adjust the artboard to fit which is super fiddly.... (not like in Photoshop where it sizes the artboard to the size of your copied selection).
Am I missing something really simple?! I have heaps of little elements I need to save separately (without a huge artboard behind them) and I think I might go crazy if I need to create a new specifc size artboard for each of them.
I used a 2d polyline to create a surface boundary for a surface created. The polyline is a closed loop. For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.
My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary. If I don't have a surface boundary the entire drawing surface shows up no problem.
The purple polyline is my boundary and the light blue is the surface created within the boundary.
Is it possible to export created surface from civil to revit architecture? If yes , How? And if its not possible - maybe i can somehow import cogo points to revit?

I've seen this bug for several versions and it's still present even in 2014. After viewing a corridor section, doing an inquiry, then clicking the Close button to get back the corridor is not able to be selected. It's "invisible" to the cursor. The only way I've found to get back to normal is to zoom out a bit, do a regen all, then a save. That's the only way to get the cursor to select the corridor again short of restarting C3D.
I can't recall what version I first noticed it in, but I think it was 2011 or 2012.
EDIT: Forgot to say this doesn't happen every time. I can't pinpoint what changes between tries, though. Usually, once it happens and I do the previous steps I can select it for a while. Then the bug hits again and I have to do the steps again.

How to export a dwg file to bmp.
Autodesk.AECC.Interop.UiPipe.AeccPipeDocument class has a function 'Export'
Export(String fileName, string Extension, Autodesk.AutoCAD.Interop.AcadSelectionSet selectionSet)
the problem is I don't know how to contrust a selectionset with all entites in the drawing selected. I've spent the major part of the day searchin here and in the API reference. But nothing.. how to create such a selection set. I'm using the COM API in C#.net
When I select an object to view in my profile, all I get is "0 objects selected". I have tried selecting several objects in plan top view, but get "0 selected". What is the "simple" solution that I am overlooking?
View 2 Replies View RelatedIf I select some objects (i.e. pipe, feature line, etc.) and right click to bring up my shortcuts, I click on SOME commands (i.e. object viewer, elevation editor, etc....respectively, the command does not progress....it forces me back to a selection box cursor and I have to reselect the object.
For example, I select a pipe, I then right click, shortcut menu pops up, I select "object viewer", and then my previous slection is not granted and it asked for a new selection (it used to always just proceed with the command), I then have to select the pipe I had previously seleted, and the command proceeds as normal.
not a bid deal, but it slowing down my productivity having to select these items twice. The wierd thing is that it is not like this with all of my right click short cut commands...only a few!?
We have recently installed Civil 3D 2014 Service Pack 1, and while for the most part it works great, we are noticing one significant issue with profiles. In particular, when we have a design profile actively selected with grips showing, and then select one of the grips, the PVI you are editing becomes offset from the cursor. When you select a point with the cursor, the profile syncs back up as you would expect.
Just thinking out loud, but it seems like it would be some sort of graphic card issue, but we are seeing it across multiple machines.
I have used Autocad since 1991, and my current job required me to use Microstation. One feature I liked from Microstation is the ability to select and open an external DGN reference, and then match the view of the parent DGN, called the "EXCHANGE" command. In AutoCAD, you can also select and open an xref, but the DWG opens to the previous saved view, and not to the desired view that matches the layout.
My thought was to experiment with lisp or script and export the "Viewctr", "Viewtwist" and "Viewsize" variables to a text file, then importing the text file and using the "Viewtwist" as my "SNAPANG" value, then "Viewctr" as my "ZOOM, CENTER" value, and finally the "Viewsize" as the "Enter magnification or height:" value.
But, alas, I have no time, and not quite the knowledge to duplicate MicroStation's open-xref-and-zoom-to-view feature. I hesitate using the REFEDIT, which works fine for regular AutoCAD, but not so much for Civil 3D and the objects it creates (labels and other items with data shortcuts).
Is there a particular reason that the intersection wizard will not create the profiles if you select the horizontal alignments rather than let it create them by offset?? My EOP is not always parallel to the centerline. Why bother giving the option to pick out a name if it isn't going to work.

I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
If I change a point or link code in one of my subassemblies, is there a way I can build my top surface using those?
