AutoCad :: How To Create Minimal DXF File That Has Polyline
Jan 31, 2014
How to create a minimal DXF file that has polyline. I am using a C# program to create DXF File. Also if i want to hatch a closed polyline what might be the best way.
I am about to implement an algorithm that takes a point and gives minimal polygon that contains it. (or null, be there no such polygon) Observing the hatch command, one would think there is already functionality that covers this. But I fail to get on its track.
I'm trying to create (in 3D workspace), a 3D polyline which starts from the "ground" and goes up the Z axis for 45 units (meters for example), then, the polyline continues "up" but in a 45 degree inclination, and then it goes up further but still 45 degrees from the last segment.
I attached a picture of this to the post, the top line is the one I want to create, and the bottom one is what I get. The thing is that the 3dpoly command doesn't let me set the line on the Z plane, unless I fix it in ortho mode, and even after I do the first segment that way, the next one stays fixed in either the Z plane or the XY plane, but not in the 45 degree between them that I want....
P.S. - when I click the 3d polyline command, there are no options in the command area, just "specify first point...." - is this what should appear?
As part of a larger job we have surveyed the top of a dry stone wall. The client now wants that we make a solid for him from the surveyed points with a height of 2000mm (the drawing units are in millimetres).
A 3d polyline was created from the lines joining the points and I have that in the attached drawing.
I'm not looking for someone to create the wall, but I'm looking for the method to do it, as it will certainly crop up again with this new client. I've tried many ways in both AutoCAD and Civil 3D but just can't create the solid.
I'm currently trying to use the draw > point > measure tool to create a set of points around a polyline but I can't seem to get them to start at a point that I want. When I try and create the points they start from a random place.
I want to create points from the polyline to identify in the field. For example, I create a square for a concrete pad and I want to identify the corners of the pad.
i'm looking for polyline lisp. I type PLINE and type Width specify starting width is 0.0 next specify ending width is 90.0 and then i type 200mm for my distance then i choose again the Width to become 0.0 (starting and ending) then choose Arc. How to create lisp polyline?
I've been going through some examples on [URL] to create polylines and i've managed to make some code run. One thing that I can't seem to find information on though, is how to use the default AutoCAD command line options in my code. For instance, I would like to be able to prompt the user whether they would like to snap the polyline to an insertion point, everytime they create a new verticie.
Below is some example code from the site that i'm working from:
How do I go about extruding an open polyline to create a surface? I am able to extrude a solid 3d from a closed polyline ( by creating a region first) but I cant find a way to do the same for surfaces.The autodesk.autocad.databaseservices.Surface class does not have an extrude method unlike the its solid3d equivalent. I am using autocad 2012 .
I want to create a 3d ployline from a 2d polyline with curves. When I use the convert 2d polyline to 3d polyline command it places a bunch of vertices along the curve so when I go to place elevations on the vertices it takes too long. I want to be able to give an elevation at the pc and pt and have it place elevations along the curve from this info like it does on the stright lines.
I have been sent a client's construction drawing for a care home where i need to design the sprinkler installation. The majority of the rooms have got the same head positions within them, but they have all got a slightly different angle as the building is shaped like a banana. Unfortunately its not a uniform radius that i can tell as the one side is larger than the other.
So my question is this. Normally, on a square building, I drop in construction lines along the bedrooms so that i know my sprinkler heads are all the same distance off a wall, and I only need to line up one side. However, with this building being a curve, and the wall angle being slightly different on each room, how do I place an angled construction line or polyline to act as my set out line for my heads.
is there a command (or method) that will create a polyline from selected cogo points instead of manually connected each point from a create line command?
I want to create jig to insert hallow slab (polyline) everything works fine until I am trying to use an added keyword for rotation then Autocad crashes really bad (no error information). Here is a code, in comment place where program crashes.
Ps: I've already been on through the interface and tried to use text jig but no result in my case

If if manually flatten the figure using a dummy suface with the AeccFeatureElevsFromSurf command, the polyline derived from survfig.BaseCurve will then have actual arc segments.
Is there another method or a way to flatten the figure programatically first?
I want to create new vertex points in feature line and 3dpol.
I have this: try { if (obj.GetType() == typeof(Autodesk.AutoCAD.DatabaseServices.Polyline3d)) { Polyline3d p3d = (Polyline3d)trans.GetObject(entRes.ObjectId, OpenMode.ForWrite);
always catches the same Exception "the value is not within the expected range" .I have translated it because I get "El valor no está dentro del intervalo esperado". Perhaps is this: " Value does not fall within the expected range.".
I have tried it with different point3d values but always catches Exception.
With pol3d I have similar problem.

Using VB.NET, how to create a new polyline out of existing lines and arcs? I am converting existing VBA code into VB.NET, developing in AutoCAD 2010 using VS Professional and I just stumbled into this road block.
Without using programming code, this task can be accomplished via AutoCAD command by typing the PE command, selecting the JOIN option and then selecting any lines or arcs which should be combined to form a polyline.
Using programming code, however, I am quite stumped on this task. I have been able to successfully create the lines and arcs which should form the polyline, and they are all connected as well so they would form a connected polyline; I simply do not know how to proceed from here.
I would like to create a construction geometry that would behave as the Polyline Bulge. In other worlds I would like to create a Construction Arc that would have a Bulge. Upon examination, I was not able to locate any of the Construction Geometry that has a bulge.
The purpose of this is to determine the Bulge location (direction) of the polyline I am creating.
I would like to stay away from creating a database geometry, if possible.
I have run into a little trouble in trying to figure out how to create a arc polyline with entmake. I've put together the following and it works great with command "pline". I just want to know how to do it with entmake.

I am able to export to SDF but I get nothing when trying to go the two shp formats available. was a "parcel", but i exploded to polyline.
Do i need a patch to make this work? I am a C3D newbie and am struggling wit h user interface, but know that map export command line looks like it is supposed to work.
I need the features shown in a connected SHP file to display an arrow indicating their direction (i.e. -----> or ----->-----). This seem that it would be important to anyone using Map for municipal engineering (sewers tend to be directional!), drainage (so are culverts!), etc..The difficulty in doing this simple task is just adding to my hatred of Map (especially given the amount of money I've spent on Autodesk products)!
Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?
