AutoCAD 2010 :: Converting Polylines With Width And Text Into Close Polylines
Jan 2, 2014
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.
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.
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 used color to determine line widths. The plotter set-up recognizes color and assigns the appropriate line width. My new company is determining line width by using polylines. Am I behind the times? Or, is this a better way. Willing to change.
polylines in my current drawing have started to come out with a very fat line width. It doesnt matter what layer its on, even though previously they were drawn 'properly' i.e the thin line width that shows when you have show/hide lineweight on 'hide'. This doesnt happen on any other drawing tool (arc, circle, polygon etc). The lineweights in layer control are all 'default'. I can't explain this as it seems to have just happened. Is it a known bug or something?
Is it possible to assign a global width to polylines by layer?
I have made changes to one dwg and i now have to apply it to a bazillion more DWG's. But the chnages apply only to a few layers. So i was wondering if i can set the global width to these polylines by layer somehow to save me from doing it "manually"
I have a drawing with polylines that have a global width of .2 which are plotting thinner than those with a width of 0. If I uncheck "plot object lineweights" it seems to plot correctly but the lines with 0 width plot so light (or grey) that you can't see the drawing well.
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.
I need to be able to grab all polylines and change global width at once. This is a repetitve task that i have created a button for. I am trying to use this but it is not working. It gets hung up on me wanting to manually select the polylines when i thought i grabbed them with the first line.
(ssget "X" '((8 . "LayerName"))) (command "PEDIT" "w" "9")
I 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?
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 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?
Is there any way to have 3d polylines show a linetype? I need to have my contours that are created as a 3d polyline show up as a hidden linetype. These polylines came from an aerial mapping and have lots of vertices.
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...)
Whenever I select a block or polyline in 2012, the program hangs for about 1 minute. This never happens when using 2010 on the same system. Obviously this can't continue.
In 2007, I was able to select multiple polylines before typeing in PEDIT. When I was done with the command, I could then type in PEDIT and L for last and it would select the multiple polylines I had first selected. We just got 2012, and when I do L now it just selects one line. Can I change this?
I have several days of experience with Autocad 2010... The problem: I have many (a lot) polylines in my 2D drawing that are adjacent to each other, but not joined. What is a good way of joining them, so that those that "touch" each other become one? Maybe I can hatch the area, then delete polylines and then reconstruct the boundary?
I am working with a 3D model, we are using a addon for ACAD which allows us to clip the view port (ie: allows us to look at everything on the drawing but only between certain elevations { for example I could clip my drawing to only view between elevation (Z) 1000 - 1020 })
My question is: Is there any way to have text/Polylines show up even if they are not within the clipping range, specifically we would like to have a grid set up say at 0 elevation, and have it the same grid when we clip through our levels without having to manually copy it to each level we plan on clipping.
I have a problem with plotting 3D drawings. I have certain perameters I have to follow!
1. I have to use our company standard CTB files because our plots include 2D drawings that use color to define line thickness.
2. I have to use viewports, we use "carrier" sheets (paper space) to hold xrefs of all details, plans, etc...
3. I have to use Arial font and filled arrows.
The proceedure I use - I create 3D solids, then rotate them to the view I prefere (typically an isometric view), then I put text with arrows etc.. in. Once the Isometric (3D) is done I xref it into the model space of my "carrier" sheet. I then create a viewport and set it to plot "Legacy Hidden" as this allows me to plot the drawing to the correct line weights and so on using our CTB files.
The problem is that when I use the "Legacy Hidden" setting, all of the text, arrows, polylines and hatch are not filled. I have tried all of the other settings for plotting and they just do not do what I need - Hidden plots as a color image and on the black and white plotter is gray and not black, others give unsatisfactory results as well!
I have found a workaround but that won't cut it with our CAD committee, I am tring to get them to "allow" us to use 3D as a proper way to do isometrics and perspectives. This is my drawback!
One work around uses 2 viewports (one a copy of the other with the plot settings changed and the layers turned off/on then place one directly over the other to properly plot), the second is more reasonable but I have not tried it yet, it would involve creating a 3D drawing, then xrefing it into another drawing file that would contain the viewport and all of the text, polylines and so on).
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?
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.
