AutoCAD Visual LISP / AutoLISP :: Converting Polylines To 3d Polyines
Dec 12, 2011
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?
I'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...
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.
(defun c:blen (/ lSet tmp doMode objLst actDoc) ;; *lDel global variable remembered during session (or *lDel (setq *lDel 2.0)) ; default value (princ " >>> Select lines to extend/reduce <<< ") (if (setq lSet [code].........
A quick lisp routine to extract the elevations of a selection set of 2d polylines? I have a massive "contour" file composed of 2d polylines with elevations. I need to find the min and max polyline elevation in selected areas. I can't figure out how to extract just the elevations of my selected polylines so I can quickly see the elevation values?
I need to wright a routine in autolisp that selects all 3Dpolylines with the same vertex Z value.Qselect as no transparent mode and filter doesn't work.
where I can obtain a freeware lisp routine that lists the lengths of all the polylines on a specific layer or within a selection set? I want to avoid list if possible as there are rather a lot of polylines!
I 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.
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 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.
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 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 have started using Balsamiq mockups [URL]...... for preparing mockups of dialog boxes
The one I have created below still needs tweeking. Creating DCL files from xml or html?
Balsamiq Mockups is really cool and worth checking out. The dialog boxes are saved as bmml files which is based on XML. I am keen to try to create a way to translate the bmml file to dcl.
Here is a sample of what the code looks like from a sample bmml file:
I'm looking for a lisp routine which will 'convert' number of 2dsolid into hatch. Drawing contains dozens of 2dsolids (solids are on one layer, there are also other entities on this layer) which have different colors, have common verticies and edges. i.e. I want to kind of 'join' solids of the same color and convert them into one hatch colored as original solids and placed on existing layer (let it be layer '0' zero for now). Same color solids can exist in few locations - there is a case to make few separate hatches of the same color (all joined solids should be represented as 1 hatch, should not separate after separate hatch command). There is max of 20 different colors (all of them from ACI index). Solids are not crossing themself or other solids (just joining with 1 or 2 verticies).
There are also 2dsolids with 'zero-area' - represented as a line - those should be erased at the beginning (not to have a line-like hatch).
The multileader should end up on the same layer as the Mtext. (Currently it uses the current layer.)The multileader should hold the same rotation as the Mtext. (Currently it goes to zero.)The multileader should be created in the same location as the Mtext, without the user having to click. (Currently the multileader is created wherever the user clicks.)The multileader should be created without a leader. We can add one afterwards if needed, but for many we don't need a leader. (We're just using the object as mtext with a box around it.)
I would like converting all objects that has forced linetype to be on a linetype layer.
So if there are objects that have forced linetypes - dashed/hidden/phantom, etc., those entities would be moved to a linetype layer based on their forced linetype. The entities would all be changed to color bylayer, linetype bylayer.
So if there is a rectangle that is sitting on an EQUIPMENT layer, the routine would put that rectangle on a new layer called DASHED and change its forced linetype to BYLAYER.
Lastly, once that's done, the next and final step is to locate a the existing layers with matching linetype - say, OBJECTS with DASHED as a linetype, and merging it to that layer.
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.
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 have line in the drawing that exists on layer A-Wall it has different lineweight 0.05 from true wall. Now usually my routine : i select this line and then select similar to convert it to layer glazing.
i need lisp that by one command convert the objects on layer A-wall with layer 0.05 only to glazing.
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.
Is there a lisp that will allow me to do a continuous dimension, but will alternate the dimension position from low, high, low and high? If there is no lisp already created, how to create one?
See Continuous dimension attachment for example.
I work at a glass and glazing company and this is how we dimension mullion width and DLO. See typical window dimensioning attachment for window elevation with dimensions.
I have a list ("temp.dwg" "temp2.dwg") and would like to add the string "insert text here" into each item in the list resulting in ("insert text heretemp.dwg" "insert textheretemp2.dwg"). how would i go about doing that using LISP?
Is there a way to programatically set a visual style before a drawing actually opens?
We have some huge models and people seem to forget to change their visual styles back to 2D wireframe before saving and exiting drawings. Some models will crash on some workstations when trying to open in a rendered mode.
I found a lisp with a function that looked to set viewport visual styles. But it does not seem to be supported anymore. --> (vla-put-VisualStyle vport 1)
I'm trying to write a lisp routine that, when I invoke the mleader command, osmode is set to "nearest" & orthomode is set off. I then would like the original settings to be returned.
Lisp that switches back on Selection Preview i.e. thickens and highlights lines when you hover over them?I don't know why, but they are always unticking the boxes.
Is it possible to execute a certain command based on multiple selections withinin a dcl? for example: two radio colums, one with selections A and B, and a second with selections 1 and 2. is it possible to program commands based on user selections from each column? ex: if A and 1- do a command. A 2- do a different command, etc...
I tried :
(action_tile "key1" "(setq A t") (action_tile "key2" "(setq B t")
