Essentially, I'll be creating a sort of Venn diagram. So for the purposes of this exercise, let's assume it's the classic Venn diagram of three intersecting circles. But I need this to work with closed polylines, that may also have arc segments in them.
Anyway, so I have these intersecting areas, and I need to create bounding polylines for each area, and assess the number of overlaps. So, as in a Venn diagram, the areas where only one circle is present can then get shaded one color, areas where two circles are overlapping can get a different color, and the area where all three circles overlap can get a third color.
I'm clearly going to have to be converting the various boundaries to Regions, and performing some Unions. It seems I could grab all objects, convert them to Regions 2 at a time, and compare their Union'ed area to their individual area, to determine if they overlapped at all. With only the 3 cirlces, that would work, but when I have 35 individual polyline areas with arcs, suddenly this method feels like it will break down.
I have some coordinate in the excel file. How to import from excel to dwg. All coordinate i will make polyline. I know one method all coordinate copy and paste to command prompt. But i need script file or other method.

View 4 Replies View RelatedI've been looking to download a lisp that can trim (TR) and the (PE, join) polylines. two at a time or multiple... I've tried writing the lisp routine but I cannot do it correctly.. Any good lisp routine? Also, if there's one to trim & fillet w/a radius.. Hopefully there's two different routines but if there's one then even better...

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?

View 2 Replies View RelatedI have a series of boxes or polygones that I would like the program to find the 1/2 distance and create two seperate polylines from the one object.
Example:
I have a square with pt1,pt2, pt3 and pt4 respectively. After I have ran the program it would create a diagonal from pt1 to pt3 and join the rest of the lines now to create the one polyline. Also it would do the same to create another exact polygonal shape for the other half. Thus creating two shapes of equal value from one.
I work with polylines a lot to maintain Facility Space and I come across polylines that are overlapping. Is it possible to have a routine to find polylines that are overlapping? Sometimes I really have to zoom in pretty close to see if they are overlapping and sometimes it's pretty obvious.

View 8 Replies View RelatedI 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 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!
have a lisp routine that will ask you the starting elevation and the elevation interval, then allows you start selecting polylines and it assigns them new elevations based on your choices?
It seems years ago I had a routine that did this and it also changed the color of the polyline so you could tell which ones you had already changed, but I can't seem to find it now.
I need to draw a table with point number, easting, northing, elevation for a lot of points and need a lisp to read the xl spreadsheet and draw the table.

I have everything done. I thought ... The problem is when user firstly create AlignedDimension and after that he create RotatedDimension by using continous function. After that XLinePoint1 and XLinePoint2 are not parallel to the DimLinePoint (look at image).
How can I get coordinates of points selected in red rectangles?
I know that one is specified as "dimension line defining point" but what about second? How can I get its coordinates? Or maybe there is other way to get this point?
I recently wrote a lisp routine that was supposed to get the 4 coordinates of a rectangle (LWPolyline). It worked fine in *MY* tests. But when someone else ran it, the routine operated as though the order of the points had been rearranged.
How can I get the points AND the order in which they belong?
Here's a sketch to show you what I mean. As part of my troubleshooting, I had a lisp routine draw a new pline using the points gathered by my first routine. The result of that on the left. On the right is the result of that when someone else runs the two routines.
Here's the code I used to get the points.
(defun getplinepointlist(ename)
(setq ent(entget ename))
(setq ptlist (list))
(while (setq pt(cdr(assoc 10 ent)))
[code].......
I need to segregate closed polylines in my drawing by area range. Ideally, I would input the number of ranges I need.
Then somehow find the smallest and largest pline area to determine the range values (rounding up to a sensble number)
Then with the ranges determined the polylines would be segregated and moved to new layers.
I've been trying to hobble together pieces but with no joy.
I am having nearly 1000 drawings where I need to change the title block in a new format.

Is it possible to obtain a list of coordinates for view ports (with dxf codes or otherwise) similar to obtaining a list of (assoc 10) for polylines?

i have found the following lisp in a previous thread: (shows XY coordinates of the selected blocks)
(defun C:MyFunc (/ ss Index Ename Lst)

"INSERT")))))
(if ss
[Code]....
I want this information to be added to the blocks as hidden attributes so that i can extract them by attout. The work to be done is : attout to excel, autofill an attribute (numbering) then attin.
but my problem is that i cant think of a way to number those blocks IN ORDER (ie top to bottom or left to right) unless by sorting them in excel first by their x or y coordinates
can do a routine that zooms into a coordinate, based on input. So for 1A, it would zoom into the coordinate for 1A.
1A = 1,1
1B = 1,2
1C = 1,3
1D = 1,4
I will try to attempt one shortly and will post it within 1 hour.
I have a 2 point LWPOLYLINE that has the following coordinates at its end point when I 'ID' the point.
Command: id
Specify point: end
of X = 709369.3214 Y = 7153039.9690 Z = 269.2143
However if I use..
(vlax-safearray->list (vlax-variant-value (vla-get-coordinates (vlax-ename->vla-object (car (entsel))))))
I get this
(-450567.0 269.288 -450570.0 269.214)
and if I 'dump' the object..
; Coordinates = (-450567.0 269.288 -450570.0 269.214)
; Document (RO) = #<VLA-OBJECT IAcadDocument 09855674>
; Elevation = 7.17399e+006
I don't have a clue where the '-450567.0' is coming from.
I'm in Model Space in 'World' UCS, and I'm confused.. why does the 'ID'd' value not reflect whats going on when I use the vla-get-coordinates approach.
There are many other LWPolylines within the same model that behave normally.
I've attached the drawing (I think!)
