AutoCAD Map 3D :: Converting 2D Polylines With Fixed Width To Polygons
Sep 11, 2012
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.
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.
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?
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.
While exporting polylines to polygons as an autocad shp file I get an error when trying to open the file in ArcExplorer 9.2 Java edition. The error code in an invalid field length in the dbf file. Is it specific to Autocad map export issues. The attribute table is an Access file (link template).
I am creating an upper cabinet which has a fixed height but you can select different widths. What our firm does is also list the size of the cabinet. What I would like to do is make this font some sort of preset attribute and control it with the visibility states. I also want to control the font height by the scale of the drawing. my question is I if its possible and how? I've attached what I have thus far. The attribute is in teh top right corner and is justified as top right. The only way I can get this to work is if I manually adjust the font after its inserted into the drawing.
Can Lightroom constrain images to a fixed pixel width regardless of height and orientation?
None of the options in the image sizing dialog seem to be suitable; for instance constraining the "long edge" would work for horizontal images but not for vertical ones.
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.
i have started creating layouts in photoshop cs3 and i was wondering if there is an easy way to save my layouts as fluid width, as opppsed to fixed, so they resize according to the browser window. is css the only way to go?
I have some irregular shapes pure black on white background. I want to be able to make an outline with a fixed pixel size- quite small - less than 20 pixels around the inside edge as though I had taken a brush and carefully run it around the edge- it need to be more precise that what I can do by hand
I'm not suer yet whether the inside of the line should b hard or soft edge when it touches the colour, the outside edge can overlap the shape as it will be masked out- to leave a hard outside edge
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 converted a NURBS object into Polygon Object, however it has still kept the riginal" NURBS object. How do I take the visibility off the NURBS object?
i have a problem converting polygons to subdiv .when i convert i can only see the object like in wire frame and when going back to polygons i get the same issue.i get this error "// Error: line 0: No object matches name: polyToSubdShape4.
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'm having trouble with the spacing of my text when I import a .rtf file. The spaces change width based on the width of the columns. The problem does not effect all the paragraphs only select ones. If I change the width of the column the spacing of the text will fix itself. All of the text is the same text style. I have attached a copy for reference.
Trying to use the width tool, I ran into the following problem. I would like to have a smooth transition of the stroke width between two width points while keeping the original stroke width unchanged outside of that line segment.
There are four width points here: two end points and two in between. The original stroke width is 200. The two on the left have one side set to 100 while the two on the right have one side set to 50. I would like to eliminate the distortion of the line width occuring in the first and third line segments. The only solution that I have come up with so far is to place two additional width points very close to the two middle width points: one with a 100-unit side to the left of the second point in the picture and one with a 50-unit side to the right of the third point in the picture. Yet there will be a small distirtion in between.
I'm having an issue where I'm creating a white border around two landscape oriented images that are the same exact size then doubling the width of the canvas. I've never had this issue before with PS CS6.. I tried resetting the photography workspace but no luck. I tried with two portrait oriented images and the same result. I've restarted my machine. I'm on Windows 7 Pro 64bit and I'm running PS CS6 64bit as well. Thought to do a repair through Programs and Features but there is only the option to uninstall. I haven't done anything out of the ordinary except use an action a few days ago I downloaded and used from
[URL]........
and I downloaded and used the press print action.
How I can correct this? If an image is 20 inches wide and I'm doubling it to 40 it's tripling the width to 60 inches. Is there a way I can reset every aspect of PS CS6 to get back to a factory state other than uninstalling and reinstalling?
Can I reduce the palette width in LR 5 down to the width of LR 4? I am able to enlarge their width from the standard width – but how to reduce them? I am missing 100 pixels (2x50) for image view.
I'm working with a SHP file that contains 56,000 polygons, but I want to export 18 of these that are relevant for my area. Is there an easy way to do this if I create a filter based on a unique data field?
