I have some polylines that mark the edge of roadway and around the curves there are arcs in the linework. How do I turn the polyline with arcs in it into a polyline with vertices, say, every .5' or so along the curve and turn the curve into a polyline? I tried the pedit and using decurve but it doesn't work well.
Using C3D 2012
I have many segmented polylines that I need to turn into arcs. See the attached image for the method I use to create an arc from a single polyline. I need to do this to thousands of polylines. Does some other method that can do many polylines at once?
View 5 Replies View RelatedAs 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.
Any program or routine in lisp or net that can select a group of 3d polylines in the form of a tin and convert them all to 3d faces?
I know that I can take the 3d polylines and explode them to 3d lines. Then I can use map clean to delete the duplicate lines. Then I can create a C3D surface using the 3d lines. Then I can extract 3d faces from the surface.
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.
Any plug-ins out there that focus solely on this?

I basically want to convert the polylines into arcs or something. i can do this by redrawing, thats no problem, but this is a very simple drawing compared to what i normally have to deal with, this is just an example.
I am trying to extrude some joined polylines, arcs etc. The problem is some of them are extruding as a solid, which is what I want and some are extruding as a surface of the profile.
View 8 Replies View RelatedI have drawn several shapes including simple ones like rectangles with the corners filleted to 2" radii and ones shaped like a jelly bean using a combination of polylines, straightlines and arcs.
In my ACAD LT 2005 files, the arcs, fillets and polylines all appear very smooth (I set the display setting to 10,000) after I saw that the arcs had noticeable facets (like a diamond) when zoomed in.
My problem is that when I send these DXF files to my CNC router technician and he imports them into his program (EnRoute V.5). All of those arcs, fillets, and polylines still have those facets in them and do not appear smooth. When we actually cut plywood from these files, the pieces are in fact choppy.
My question- besides the display settings, is there a setting that I can change that will increase the number of control points that make up these curves that would smooth these facets out?
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.
There is a AutoLISP for extract START and END coordinates in X, Y, and Z planes, and extract length of Polylines and Arcs.?
View 7 Replies View RelatedI have a bugging problem.
I usually use Inventor to create a model from customer supplied blueprints, and then use the model to get the 2D geometry into
AutoCAD for further processing.
Now, unfortunately Inventor has a pitiful 2D drawing method, where circles and arcs that do not lie exactly on the plane end up as a spline.
They are true arcs and circles and should be true arcs and circles on the 2D view, but aren't.
What I would like to do is turn them into one.
Is there any command or method to do that?
I was hoping that Overkill would work ..... it doesn't.
I've been trying to figure out how to do this. I have a file with 41 drawings, and 7650 objects. and i want all the lines, arcs and circles to be turned into polylines. Now the Mpedit command doesnt really do it for me.
Command: MPEdit
Select objects: Specify opposite corner: 4632 found, 10 groups
Select objects:
divide by zero
This is what happens when i write MPEdit, mark everything in my drawing and press enter. Now i also tried marking a line, using select similar, and fixing it that way. but i get the "divide by zero" error aswell.
i was wondering if there is a way to convert multiple lines (non collinear) into polylines?
this to be able to add the "global width" property to the objects.
I've been sent a series of CAD drawings in which the author has used global width to define the appearance of features. I need to import this into our GIS, which for reasons too complex to bother with won't import any attributes such as width. I don't want to lose the information recorded so was wondering if it's possible to create a closed polygon to represent the shape of the line. I guess something might be possible using buffering, but I can't figure out how to use the existing line width.
View 9 Replies View RelatedI need to be able to convert "polylines" (as opposed to "2d polylines") to 3d polylines. Here is the issue: the polylines that I want to convert have object data attached to them and they are at the proper Z elevation. When I use the "Convert 2d to 3d polyline" function, the conversion does take place, but all of my object data is removed from the object. And since one of my attributes reflects the overall elevation of the object (which all of the verticies will be the same elevation - even though it will be a 3d polyline), there are too many objects to individually update the attribute information when I am pressed for time.I am working in Civil 3d 2010. Any way to do this using Civil 3d?

We just upgraded to 2013, and one computer is having a weird issue. There is nothing in the drawing. He draws two polylines. When he goes to fillet them, it says they are non-coplanar. The properties palette says both polylines are elevation 0. why this is happening and how I can fix it?
View 4 Replies View RelatedThe Straighten method seems to always default to the first vertex of the polylne, which is great if you want to start there but what if you wanted to delete the 10th to 15th vertex?

View 9 Replies View RelatedHow do you suppress viewing drawing polylines in the cross section editor in 2014. I never had this problem in 2013, now it shows all of my polylines in the cross section editor. I thought it would be under 'display objects'.
View 4 Replies View RelatedI use slope symbols instead of contours to keep my maps less busy. Unfortunately I can only change my cut style and fill style to slope symbols with grading by right clicking on the little diamond in the grading and selecting grading properties.
I have created a surface with 3d poly lines not by creating grading and got contours that way, How can I create the slope symbols in a surface. I tried xploding them and then creating a block and using the measure tool on the 3d polylines but it doesn't do anything.
Picture 01 is the contours
Picture 1 is the contours turned off and cut/fill styles turned to slope symbols.

View 6 Replies View RelatedI'm using AutoCAD Civil 3D to model inner city utility construction projects. For my research project, I need to include water and storm pipes, but also various sorts of cables. Currently, I'm manually creating cables profiles using plines from existing 2D drawings and the sweep function.. a very cumbersome taks.
I was wondering whether there is a way to speed this process up. At the moment, I draw a circle, copy it myriads of times, and sweep each along the dozens of plines (one by one). I cannot select multiple lines and sweep them all, can I?
whether I can select mutiple plines to sweep all at once?
Is there anyway to read the featId attribute of a polyline and assign the elevation to the polyline? All the polylines are at elevation 0. Is there a lisp routine to do this?
PS: I do not have the shp file from GIS only the AutoCAD drawing with the polylines already created and their featId.
Having trouble with splined polylines in 2011? I tried to edit a splined PLine and the program was unresponsive for about 10 minutes. After I edited the spline the drawing size doubled. I reverted to a backup and erased the spline. I drew a Pline and used Fit Curve with no problem.
I draw another PLine and didn't like the results. So I tried to spline it and now Civil is unresponsive for the past 5 minutes. I'm doing this on a different computer. So it isn't that particular machine or installation.
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.
View 9 Replies View RelatedI received some dwg files to show existing utilities from a local municipality. I thought the files would come as shp files, but they are dwg files. The drawings/dwg files show the layout of pipes, but the pipes are polylines. The polylines have data attached to them. The properties show material, size, length, slope, etc. I am trying to label the pipes/polylines and I can't figure out how to get the information from the polylines.
