If i create a box in 2d,after extrude,it is a solid;but if i create 4 lines to form a box ,after extrude,it is 4 walls?is it possible ,if i have many lines,to convert mulitiples lines to polylines and i can create a solid easier?

Joining lines into polylines in autocad 2007. Basically, I got stuck when joining several lines together using PEDIT and then Join. At the start, it was very smooth process with no drama. Then, I came across two polylines and wanted to join them together, it just did not work. It works most of the time. Why I can't join certain lines together or two polylines together. This is a 2D drawing CAD.

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?
View 7 Replies View RelatedI wonder if there is a way to get an intersecting point coordinate of two polylines(lines) programmatically.
For example, like in the below sample picture, I need to get coordinates of the points in the red cycles.
Is there any method that I can easily use?
Could I get a sample code snippet that computes the coordinates? (in C# & ObjectARX 2010 if possible?)
I've looked up "Through the Interface" and this disscussion group. couldn't find any useful yet.
I have several featurelines that I wish to explode to be 3D Polylines (bad, I know, but it's a test for a way to get data across from our design group to our survey group).
Last week, in this drawing, I exploded a large selection of featurelines and they all became 3D polylines, preserving their elevation data. This week, I drew an additional set of featurelines in the same drawing. When I explode them once, they lose all elevation data, becoming lpolylines at z=0. Additionally, the Prospector shows me several errors: "breaklines not added to surface" or something similar. Which is an odd result for the explode command.
Why did this work once but not a second time?

Despite numerous different efforts, I can't get my polylines to plot at the same weight as my standard lines.
I'm not sure whether my issue is specific to lineweight, thickness or global width..
I've tried the latter two via qselect for all polylines within my selection; this didn't work.
I've put all selected lines (std and poly) into one layer with a layer default lweight. This didn't work either.
My workaround was to xplode all polylines within the selection and then they all plotted as required.
I'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?
What is the blue flag flyout? I cannot move any lines or polylines without it moving whatever is attached. I do have service pack 1 installed.

View 4 Replies View RelatedI have the need to put COGO points along the vertices of multiple 3D polylines in a DWG. I know how to do this individually for each 3DPL via the "Points>Create - Miscellaneous > Polyline Vertices - Automatic" or "CREATEPTPLYLNCTRVERTAUTO" command. Need tip on how to do this in a batch format for all the selected 3D PLines in the drawing without having to select each individual 3DPL and having to hit return to enter a description for each individual vertex? I can do without having to add a description and can leave each description blank or enter the same description for each.

Lisp (or a native way) to lengthen multiple polylines or lines at once to the same length by entering that length? I found the following lisp routine which extends a line an entered amount, but it has to be on a specific layer, and I want to enter the finished length, not how much to extend it.

View 2 Replies View RelatedIn 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?
View 7 Replies View RelatedI 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!
I'm trying to create about 150 cross-sections, each consisting of 9 closed polylines of which I have created the coordinates. My issue is making the list of coordinates create separate polylines instead of one enormous polyline. Any way to setup the columns, perhaps with blank rows, some way of applying ASCII code, etc. to automatically break up these polylines? (even if they aren't closed that's fine, I just need to make the polylines separate.)
View 1 Replies View RelatedI have few text labels and lines in a drawing that supposed to have black color.
However, color at some point changed to grey.
Color- by layer, transparency- by layer, viewstyle- 2D Wireframe...
The thing is if I double click on a text it turns to black but after regenall it turns to grey again!
Already did restart and everything. Looks like there is maybe some variable for color control, I don't know.
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.
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?
View 2 Replies View RelatedIs 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.
How can i transform 1000 lines to 1000 polylines ?

I have a large group of lines that I want to get a total length of. Right now the only way that I know how to do this is to highlight them all and use the list command but then I have to go through the text box and write down each line length and then add them up. This is fine if I have only a few lines but when you get into the hundreds or thousands it becomes a monster task.
I tried copying the text box data into a Word document, removing all of the text except for the line lengths and then dumping that into Excel to calculate. This works ok for a hand full of lines but is not really practical.
I know that there are LSP routines that can do this in the full version of AutoCad but LSP is not supported in AutoCad LT.
Is there a way to automate this process in LT?
Or maybe extracting just the length data from a line to a text file where I can send it to Excel and use Excel to add up the lengths?
I need to divide thousands of lines into half, but AutoCAD divide command can only allow you to select one line at a time.Is there any way we can divide multiple lines at once.
