Recieved a ACAD converted Microstation File for use in an upcoming construction project. Would like to convert all of the existing ellipses to polylines. Have read several threads that lead me to believe redrawing them is about the only real way to do it. Posting here in hopes of a solution. Drawing contains 127 ellipses, and I dont want to redraw all of them!!
Currently on C3D2012.
I have LWPOLYLINEs that represent a cross section of a train tunnel. Each LWPOLYLINE lists its 2D points in an Object Coordinate System.My task is to create 3D Polylines in WorldCoordinateSystem using those LWPOLYLINEs.I have posted a drawing with sample objects.
I have attached a sample drawing. Drawing was created with Civil 3D 2013, but I exporttoautocadr12dxf'd it and then save to 2004 dwg so most should be able to open it.
How to convert pline to Alignment C3D 2014
View 1 Replies View Relatedhow I can add in some vertex's at regular intervals on a fline or pline?
C3D 2013
I have some imported points and a polyline created with those.
When i try to rotate the pline around a point it seems that some edges are locked?
Even if I copy this pline in an empty area alone and try to rotate it again i get the same resulsts.i tried the move comand with a vertex as a base and the same reults.
I do not know where the edges are locked .
This is with Civil 3D 2013. I am able to create a pline by offsetting an alignment using any drawing on any other workstation in our office, but on my machine I get an error: "1 object(s) were filtered out." when I try to select the alignment.
This leads me to searching for some system variable or something that is different on my machine.
Basically I have 3dpolylines and some Splines. I would like to create a road file that uses the geometry of these objects to create a single line/crest of road file.

I have a line or a pline segment and i want to start a line from a point laying there and go perpendicular outwards. Is there a way to do it with tracking?
Yes, i saw the command draw line at an angle but i find it a little bit complicated for a simple task like that. I am sure autodesk have a simplest solution about that.
If i am already at the draw line mode and i can easy catch the tracking perpendicular to previous segment but if i want to start from another line and go perpendicular i cannot make the tracking work.
I have terrible lag whenever I am drawing a polyline. It seems like it is taking forever to render the preview of the line when I am dragging the line across the screen. I would prefer to just turn off the line preview if at all possible. So far, I have not been able to find a way to do this. When I say preview of the line, I am talking about the transparent line that follows your cursor after you start a polyline and exists until you click to place the line where you want it.

what I need to do is to flatten a spline into a pline because I need to measure its diameter.
I know how to it with a 2d spline but how can I manage in case I have a 3d one?
I'm using AutoCAD 2013 and it will not convert a p-line to revcloud .

View 9 Replies View RelatedI use AutoCAD Mechanical 2012. The attached cad files are shown. One is filled on arrow and pline. The other is not filled on arrow and pline.
These file used same system variables. How can do this? I would like know for system variables that possible can do.
whe i try to draw a pline it accepts the first numerical entry but locks up on the second point. Also when i use this command no matter what layer it is on the line becomes very fat

Is there a way to add/remove vertices from polylines using the grips method similar to editing hatch boundaries? I know of "Pedit" and "edit vertex" then "add vertex" but this seems like too many steps after working with hatch boundaries.

I know to PE - W - x Value, but is there a command that changes what a pl's width starts at?
I want to create a segmented polyline with known angles / lengths, but I want to do this in 1 operation without having to copy/rotate/chamfer etc.
I'm sure it has something to do with UCS, but I've not used it in quite some time, I am stumped and everything I have tried so far has failed.

I use Pedit alot on straight line but won't work on circle. As you can see on the picture below when i changed the lineweight to be bigger but the circle is still the same.

what is the setting to tell a line to extend to the face of a pline when that line doesn't actually intersect with the pline? see image below...line 1 will extend to pline faces A and B, but how do i get line 2 to extend to those faces? i know this worked when i used autocad 2008 but i'm now using 2012 LT so hopefully it still works, i just don't remember the command name to control it.

I have bearings and distances but I am wondering if using PLIN is the best method to draw parcels in AutoCad Map 2012. I have a layer of the Townships, Ranges and Sections that I hope to align with the drawings. Most of the time it looks okay meaning they line up and for the most are where they are suppose to be but ever so often I have problems.

View 2 Replies View RelatedI have just started using Autocad 2010 (i know i know, its not the latest )... but anyways.
I am facing this unique problem where i have a 3d solid object in the drawing, and when the first point in a pline command falls within the boundary of the 3d solid, autocad automatically assigns some of the properties of the 3dsolid to the new polyline i draw.
so for example, in the attached file, even if i am selecting pline command and starting a command within the rectangle (start point shown as a circle), it automatically changes the z coordinates so that the resulting pline is angled to the xy plane.
I a not sure how this happens, and how I can turn it off.
In continuation with thread All to Pline . I want to add one more function to this lisp i.e. Join all the objects selected.
Can this be done?
I tried this:
(command "_.pedit" "m" ename "" "j" ename "")or (command "_.pedit" "" "j" ename "" "")
But it gives me an error something like this:
Requires numeric distance, two points, or option keyword.
