AutoCAD Map 3D :: How To Convert Mpolygons To Polylines
Nov 27, 2013
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...)
On my file I have some polylines that are the streets. So, they look like rectangles and curves, etc. I am working also on a 3D Model, and what I have to do next is to extrude them. The problem is that those polylines are not polygons, and so, they are not solids when I extrude them. I tried to use the command BO but it says that the lines are not closed, and I checked with OSNAP and they are! Is there any way to convert those polylines into polygons?
I want to turn this shape on the left, into one like the one on the right... i.e., not so many points.
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.
how do I convert a section that I created using an alignment and surface into a polyline. I want to be able to manipulate and easily use the section for another program.
I need to convert all polylines on layer to blocks. Each polyline gets replaced with a block that is near the approximate center of polyline. it can also be at the first or last node of pline. or just near the center. (polylines are rectangular).
I have a drawing that started as a pipeline network and am trying to easily convert the pipes to polylines or something of the sort to export to shapefiles.
On several occasions I have had to convert a group of lines to polylines but had to select and convert each line one after the other. Instead of one after another is there a way or a command to select all the lines and convert them as group into polylines?
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?
In autocad 2013 is the best way still to convert data you have connected to, for example a shape file, as feature data in order to convert that into polylines and text is the best method saving it all as a seperate drawing using the "save as autocad drawing command"? Is there way to do it individually in the current drawing so that I do not always have to be saving things out as seperate drawings and then copy and pasting them back into my working drawing?
I drew a cube using polylines by changing ucs. I want to join the polylines so that the cube contour becomes one single object.
Since the lines are in different planes I can not join them. How could I unite those 12 lines so they become a cube non solid(I plan on placing a sphere inside some of the cubes and then use "shade" for visualization so if the cube is solid I won't see the spheres).
I need a function that allows to convert the polylines selected with a width globalize defined in a double closed line (spaced by the same width of the polyline), with a hatch inserted automatically defined.
Brilliant idea to draw raceways quickly: instead of making handmade double lines, connect, enter the hatches all by hand, you could quickly draw the polyline with width identical to the size of the duct, and then the lisp transform it into a duct more aesthetically pleasing if compared to the full polyline!
When converting metric 3d polylines to feature lines with units set on metric, drawing properties metric and using the australia/new zealand settings and command "create featureline from objects", for some reason the resulting 3d featurelines end up imperial?
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.
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 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 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.
I have a task of finding the lines which are overlapping on each other (not completely). One Plines start or End point will be on another lines(without snapping). Need to find all those such lines..
