I'm using the FILTER command to do this. I've added elevations 410, 420, 430, ect to the list, with a ** Begin AND at the start of the list, and a ** end AND at the end. Nothing gets selected.

Any way to get an expression that calculated the difference between two points and pick up the results as point elevation.
View 5 Replies View RelatedI have a number of 3D polylines that where exported from SDF previously created. They have numerous vertices, each one with a given elevation.
How can I create/highlight the higher and/or lower point in each 3D polyline??
A different solution would be automatically breaking these polylines in slope changing points (i.e. high or low points).
I understand that i can create points according to slope or elevation, but it has to be done manually, each poly at a time, and by tipping numeric values that i am sure that a powerfull software (as Civil 3D is) is able to calculate using the drawing information.
What is the setting that will keep the last elevation entered when creating points?
View 0 Replies View RelatedUsing Civil 3D 2013. I've exported my Civil 3D points to an SDF and then to a shapefile. I cant get the "Z" elevation to come with it. Northing and Easting is correct, only problem is that is holds a zero elevation. how I can get the elevations to show correctl in the shapefile?
View 9 Replies View RelatedI have thousands of polygons (and circles) which represent 2D foundation detail.
I have XY Location data (XLS, CSV etc) and Z's for the tops and bottoms of all these objects. (and hence, AutoCAD points)
I have used SHP data before (for the building footprints, and tops) whereby the top and base data is included in the data and I have use mapimport with change properties to thicken polylines and create quick 3D objects above ground.(This was created by others using a method similar to what I want, but in a competitors GIS...)
I need to do the same with the footings.
How can I create a "search" that says - for each polygon, look for a single point inside, and report its elevation and attached that to the polygon as data? Or, create a SHP of all these polygons with RL data queried of the internal point.
The points arent necessarily at centroid, which could be an issue. (Most are, however)
There is no keyID data between the polys and the points (so data joins wont work)
A friend did this very quickly for me in an ESRI Package, surely MAP can do the same!?
Map 3D 2012, and a monstrously powerful CAD workstation... just, er, not the knowledge to yet pull this off.
I have a rather odd situation. I have input a small table of survey points (we don't have access to a data collector, so it had to be manual).
I have a properly located and back-sited setup, with all of the points located in 3 dimensions.
The Northing/Easting/Elevation data is calculated and displayed for all of the points in the "observations" table accurately.
Every point has the same display/labeling properties/settings, but only 2 points properly display the elevation as calculated.
The problem seems to be that the points aren't accurately retrieving the Elevation from the table.
For some reason, in the “Properties” dialogue for the points that display properly, the “Point Elevation” field actually contains a number; whereas the points that don’t, the same field reads “*PROPERTY NOT SET*”.
This makes no sense, because in the table that defines the points, the elevation is accurate for all of the points, and I can’t find a difference in the table- or in the point properties- between the correctly displayed points, and the ones that are missing the elevation label.
I recently upgraded from Civil 3D 2009 to Civil 3D 2014. In Civil 3D 2009 I was able to set the point style 3D modeling to flatten the point to a 0.00 elevation. In doing this I could move the point around freely using the nod grip without the elevation changing weather I used object snap or just freehand placed the point.
For some reason with 2014 when I grab the nod grip it changes the elevation to 0.00 as soon as I move it from the location it currently sits despite the fact that everything is set the same as it was setup for 2009. Is there a setting that I need to change to fix this or is there a new way to go about moving the point without using a bunch of different commands.
When creating surface profile Is civil 3D use interpolation to get elevation of unknown (points which not having elevation data) points?
Or just join elevations which have elevation data(input data)?

How to change the number of decimal places of the elevation of points?
as the points are labeled with their elevations, I couldn’t find how the number of the decimal places of the elevation be chosen. In this case, I wanted to let the number of the decimal places to be zero.
How to set the number of the decimal places to be zero or 1, for example? how to sepcify it height (size)?

View 8 Replies View RelatedI am working on a flood inundation, I would like to find a lisp or command(i'm not finding) to connect two points with a given elevation following the surface file or surface entities.
here is a small section as example right now it's just guesswork, some of these have taken a week to connect all the sections.
I was wondering how to develop a Selection Set Filter that will select only Cogo Points? I know I need to use Dxf.Start as the code, but then what's the string associated with Cogo Points? Can't find any documentation on this or any Civil 3D-unique entities...I know Line is just "Line" and "Arc" is just arc...but Polyline is the unintuitive "LWPolyline" and "Cogo Point" isn't working.
View 5 Replies View RelatedAny way using autoCAD LT 2014 to get CAD to display the elevation heights of survey points without having to type the heights in text bozes next to each individual point. i can insert a field which displays the elevation of the point but doing this again i would have to do every point individually.
Another words is there a way to select all the survey points required and get CAD to display a certain property, which in my case is the elevation height of that survey point, next to it? so it looks like x 23.35 x 23.57 etc..
I have a problem with lines that begin and end outside the Z is zero, and polylines with elevation outside the Z zero. The difference is very small, for example, -0.00000112, or 0.00000078. I checked the possibility of using the Flatten command but does not always work, even though there hatches in the drawing. Polylines and Blocks also cause problems with the command by flatten.

I'm using the exporttoautocad command to convert a 3D drawing with a proposed surface (a TIN object) into a drawing with just contours (polylines with elevations). My original drawing is in feet and has a NAD83 state plane coordinate system.
Everything seems great in the exported dwg, except it is converting the elevation units from feet to inches!? A contour that was originally at an elevation of 7.0 feet, ends up at 7 inches in the exported drawing. Spatial coordinates are preserved.
I am working on an electrical plan and am having some issues setting the elevations on the lighting blocks that I inserted into the drawing. When I select all the lights at once to set the elevation (or Position Z, as there is no elevation option) to 14', they all go to different heights. I need them all to go to 14', which is the ceiling height. The lights that are recessed need to have the bottom at 14' and the lights that hang need to have the top at 14'.
Attached is the file for reference.
Is there a setting I can change so if I am drawing an object (line, polyline, etc.) if I am snapping to a contour line, the objects will NOT take on the elevation of the contour line?

-changing osnapz variable
-latest civil 3d service pack
A few weeks ago I did not have this problem but once my computer was switched to the company's global server and c3d was reinstalled the problem appeared. Furthermore (post switchover), when a colleage of mine prepared a simple test drawing with just a line and a point, he was able to snap to that line without the point changing elevation. When he sent that drawing to me and I tried snapping the point to the object, the same problem occured with the point taking the elevation of the line object. I suspect it is a system variable issue

I am new to programming in general, but really new to C#. A little to discribe what I want to do.
I need to creat a command that once I run it, I get to choose an excel file that will be filled with points in a D,X,Y,Z format. (points range from 1-??) I know there are other ways of doing this (importing text ascii) but I need to cut down on the time and steps. This is something I do on a regular basis for people to convert different coordinate systems.
how to do the basics right now, I am just having trouble getting to the point that it will pull the info out of an excel file. I do not have any code right now to share to show my progress either.

View 3 Replies View RelatedIn previous version you can rotate the UCS around the Z axis by tying UCS Z at the command prompt and then you were prompted to select two points to defin the angle. Now it uses a point at the ucs icon as the first point and only allows me to pick the second point. Is there a way to pick two points to define the UCS angle? I tried setting the UCS Origin to the first point and that did not work.

I am trying to use the DIVIDE command but can't see the points (nodes) it creates after the command is complete. I have the OSNAP setting on to snap to nodes which I can't even see. The QSELECT command let me see that they are indeed in the drawing, and that is the only way I can select them.
View 1 Replies View RelatedFor some reason my computer is the only one in my office that is doing this. Whenever something is put on the def points layer I am unable to select it afterwards.
Such things have been:
1) The viewport in paperspace. The view cannot be resized but I can still click inside the viewport and work without problem.
2) Any line, block, etc made or put on that layer.
From what I've read others are saying is your layer 0 locked or frozen? It is not. Also in my layers manager nothing is turned off to make it any different from any other layer.
