AutoCAD Map 3D :: Creating An Image From Polylines
Apr 7, 2011
The Project: Determining erosion setback elevations for hydroelectric requirements: increased water levels due to flooding.
I'm trying to create a DEM from contour polylines that were downloaded from a Government website.
The 2d shp file was imported and since the area in question is relatively small I've set the contour lines to the elevations they represent by hand. Now I'm trying to create a pseudo DEM from them. I need to create a 3d surface and then from there determine a rough idea of an erosion setback at a certain elevation.
Basically, the contour lines are set to 710', 725' and 750', the elevation setbacks are around 720' and 730'. Is there a way to create a surface between the three elevations and then show single solid polygons at the 720' and 730' elevations? And further is there a way to create a polyline at those two elevations to show an approximate setback on a sketch of the area?

I have a network of 3d polylines, how can I convert this to a 3d object? In 3ds max I can use a surface modifier to convert it to 3D. Is there a workflow inside of AutoCAD?

They send me a file that has polylines as contours and when I try to do the surface adding contours an error appears saying that the breaklines couldn't be added because they crossed a breakline, I don't understand why.

I am creating a surface from polylines and the surface is not being created per the what the polylines represent. These are simple 5:1, 3:1, and 3.5:1 slopes. The surface wants to create curves instead of straigtlines (see attached).

I have a series of boxes or polygones that I would like the program to find the 1/2 distance and create two seperate polylines from the one object.
Example:
I have a square with pt1,pt2, pt3 and pt4 respectively. After I have ran the program it would create a diagonal from pt1 to pt3 and join the rest of the lines now to create the one polyline. Also it would do the same to create another exact polygonal shape for the other half. Thus creating two shapes of equal value from one.

As the above mentioned, I have a drawing drawn using polylines with width from someone. The width of the line are suppose to represent area,
To put things into prospective, here is an example:
The polyline is 10 unit long and with a width of 2 unit wide. If i explode that polyline, it will become a single polyline without width. The line are suppose to represent 10 unit long and 2 unit wide; representing an area.
My question is is there a way to change the line above directly from polyline with width to a close polyline (4 x polylines) of 10 unit long and 2 unit wide.

Is there a way of converting 3d polylines to polylines with an elevation?
I have a dwg of contour information, the contours are 3d polylines, because they are contours the z value is constant all along the line, so there no question what the elevation of the polyline would need to be.
I need to do this as I then need to import the dwg into a GIS programme called MapInfo whch doesn't read 3d polylines.
I have access to AutoCAD 2004 or 2005LT.

I am in the process of sorting out some wood engraving and acid etching of some brass plaques. I would like to know if it is possible to produce a cad drawing from a vector image and if so how ?
This is one of the two images I would like to turn into a cad drawing.

i am doing some artistic designing with AutoCAD 2013 and would like to create high resolution images from the drawing in order to make large high quality prints. i have found some tutorials on google but they all refer to accessing the 'Add a plotter wizard' in the tools menu but i do not see that option here in AutoCAD 2013. in fact, i can't seem to find any plot settings anywhere. i remember in the old AutoCAD you could go to the file menu and select 'plot' from there.

I am using MAP3D 2013 and trying to create a raster image file for use in anther document (the document will not accept a dwg or dwf file, only a raster image).
When I use the JPGOUT (or PNGOUT or BMPOUT or TIFOUT) command I can select all of the objects and viewport; there is no problem creating the file. But when I open up the raster image, only the viewport outline and objects in paperspace have come accross; the viewport appears empty.
In MAP, the viewport is turned on and I can see everything as intended.

Over the past year I have been working on quickly generating vertical cross sections through 2D lines. I have exhausted all of my connections with fellow AutoCAD users and I still haven't found an efficient solution.
The material I'm working with is a bunch of polylines that kind of resemble branching tree roots from dozens of trees. The polylines sprout from seed points and then branch and cross each other as they move down. I need to generate many vertical sections through the lines. Since the material is composed of lines a slice along a plane would only generate points. I need to take a slice of a volume of lines so that the paths are preserved.
I have tried creating two vertical parallel planes and then using the slice tool on each plane. This would break up all of the polylines at the intersection with the planes so I can manually delete all segments that are not between the planes. This is time consuming, and also leaves room for error when manually deleting line segments.
The ideal tool for efficiency and accuracy would be Section Line. I could create a section line, convert it to a volume, and generate a 3D section with the option to save the section to a new file. The problem with this is that the section tool only works on solid 3D objects. I have considered sweeping a small diameter circle along each polyline to give them volume, but this would take days to weeks of work.
Is there a better tool or method for creating 3D sections of a volume of polylines? Are there any tricks that can be used to allow the 3D section tool to work with the polylines? Maybe I could convert them to a different type of object.
I am using AutoCAD 2013.

I have a drawing that is a topigraphical survey in 2D its constructed of 2D polylines, I need to convert these to 3D polylines so I can add a Z vertex then move the lines/contours to their Z value currently illistrated by text on the plines.
change the line types and easily move the lines to their correct Z value?

I'm trying to creat this effect. The best example I could find is the Windows Media player. Notice the beveled areas. They are not square with sharp corners or rectangular in shape. They are wavy. How is this done?

I'm trying to make a new .gif but I'm having problems with the black line that you get when you make a new image. I'm using a transparent background and I'm wanting to get rid of the black line around the image or change the color of it to match the logo.

I have drawing with lots of pol)lines which are intersecting themselves.
I would like to divide all selected lines by the point of intersection.
I have this
[CommandMethod("BRA", CommandFlags.UsePickSet | CommandFlags.Redraw)] public static void TestIntersectAllLines() {
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; Database db = doc.Database; Editor ed = doc.Editor;
[code].....
But it seems to doesn't work properly - some lines are not erasing, some are not intersecting in each point.

I have drawings at the moment where I need to convert some lines to polylines. I know you can use PEDIT and PEDITACCEPT=1 but i want to match properties at the same time.
Just wondering if there is a comand or lisp routine that duplicates the MATCHPROPERTIES command but converts lines to plolylines at the same time, this way all i would need to do is type in the appropriate command and select my source polyline and get multiple duplicate polylines by clicking the lines I wish to change?

In the ipt. sheet metal file, we create the flat and export face as a dxf file to use in our cnc software.
The problem is that our shop guy cannot open the dxf in the cnc software (he gets an error) unless we open the dxf in Autocad and explode it and resave. For some reason, Inventor creates the dxf with the perimeter of the part as a polyline.
Is there a setting that could keep it from making it a polyline.
It is time consuming to have to go into Autocad, explode and resave every sheet metal part.
We use Inventor 2010.

We need to take polylines from AutoCAD Map 3D to 3ds Max and rename each polyline to have a name of something like "Building Number-Room Number", both of which are defined in our properties for each polyline. Because none of this data is kept on import to Max, we need to do this all in Map 3D, which we are not experienced with. Is there a way to do this, and if so what? We are importing the .dwg files in Max with polylines as splines.

How do you draw polylines in different planes? If I set the normal it does nothing. I would like to use polyline2d because you can use bulges and not with polyline3d.

I'm trying to automate a simple yet massively tedious task at the moment. Certain layers of my drawings contain 3D Polylines that have to be converted to cylinders. What I need to do is select all 3D Polylines in a specific layer and automatically convert them to cylinders, these cylinders will all share the same hardcoded diameter, however will retain the x,y,z, positioning of the 3D Polylines. The way that I'm approaching i'm attempting right now is to use a selection filter to select all 3D Polylines, save their co-ordinates into an array, create the cylinders using these co-ordinates and then deleting the existing polylines.

Is there anyway to lock the direction of polylines? I have several drawings with diversion ditches. I use the linetype to show the direction of flow but antime I have to change ltscale or linetype, it reverses the direction. This can be an easily overlooked situation and a time consuming one to correct.

I have topo contours that are splines. I want to flatten them so they become polylines that I can give elevation values. When I flatten some, portions of the topo lines become circles.
How do I fix it?

I believe I have a settings issue for which I am stumped- My polylines are visually appearing grey when I open just this one particular dwg. I have rechecked my layers and plot settings and all seem correct. When I click on the polyline (or any of them) they are on the correct layer and also by color layer and in the properties box - everything seems to be correct. I can draw new lines and they are the correct color - UNTIL I close and reopen the dwg and all polylines change to gray - BUT only visually - the layers still have the correct color and they will not even plot in color.

I'm in search of a way to convert mpolygon objects to polylines in a way so they stay on its original layer. We use Layer Explode (lexplode) from Vianova but it doesn't work with Autocad Map 3D and they are not planning to develop it.

For my project, i'd like to convert Mtext into polylines (or lines or other...) with vb.net (why? because my company is working with laser, and laser can't write text like this, we have to convert it into lines/arcs/splines etc...)

I've got ObjectIds of a bunch of arcs that I need to convert to polylines for further processing.
I was thinking of using the COM interface and sending the PEDIT command and converting the arcs.
The only problem is I don't know of a way to put the objectids into a selection set, then call the pedit command and use the previous selection.
