AutoCAD .NET :: Filtered Objects Into A Single Polyline?
Jul 11, 2013
I am filtering for objects based on layer as shown below.The layer consists of lines and arcs.Is there anyway to convert all these entities into a polyline and get the object id of this single entity.
Dim acTypValArPath(0) AsTypedValue
Dim sf As SelectionFilter = New SelectionFilter(New TypedValue() {New TypedValue(8, "FirstBias")})
Dim ss As SelectionSet = acEditor.SelectAll(sf).Value
Dim idarray As ObjectId() = ss.GetObjectIds()
[code]....

I would like to take all the vertices out of a multiple-vertices polyline so that it reduces to just its start and end points, can this be done?

I am looking for a way to extract (filter) all polylines, and loop a lisp based on the number that are found within a "W" selection window.I am frustrated getting "malformed list" or errors, even after defining "n" for repeat.The code I have so far looks like this:
(defun cWW (/ p1 p2 sspw myObj ss)
(setq p1 (getpoint "
Pick first corner: "))
(setq p2 (getcorner p1 "
Specify opposite corner: "))
(if
(setq sspw (ssget "W" p1 p2 '((0 . "*POLYLINE")))
[code].....
Without the (repeat () portion, it was working ok with selection window, however it only would run the commands for a single polyline. What needs to be done without overhauling the code? The lisp has worked on a drawing-wide basis, however needs to run on only on user-windowed polylines since there are other polylines within the drawing which are attached to layouts via viewports.

Is there a command to combine two 3d polylines into a single polyline? Either combine, take the mean between the two lines, or draw a third line at the mid distance between the two original lines?
The lines are created (in a .dxf) by a GPS unit in the field, and represent tracks needing to be mapped. Typically we would drive out a track and then drive back on the same track; this gives me two 3d polylines. Because of GPS errors it better practice to log the roads/ tracks twice. The lines can have from 2000 to 10000 vertices, so manually drawing is not an option.

I have long used the following lisp to convert multiple single text objects into multiple mtext objects (i.e. make each text entity into separate mtext entities).
; T2M - convert individual Texts/Dtexts to individual MTexts
; modified by Xanadu - www.xanadu.cz
;
(defun C:T2M (/ ss i elist)
[Code]....
However, the mtext entity always moves position slightly (compared to the original text entity) after converting the object. better lisp that converts multiple text entities into mtext entities (which are all separate still, i.e. not joined together) without the position of the entity changing?

I've managed to create an array using custom blocks. This array is obviously comprised of "x" columns and "x" rows. What i'm trying to do is have the ability to essentially link all of the objects per column (and/or per row) with a polyline. So if i have 5 columns generated, I would like to have 5 polylines extend over those columns. Any example of how to do something like this. Essentially what i'm looking to do is create something of a grid using the objects in my array as place markers. And now for a bit of existing code:
//Use the upper-left corner of the objects extents for the array base point Extents3d acExts = bref.Bounds.GetValueOrDefault(); Point2d acPt2dArrayBase = new Point2d(acExts.MinPoint.X, acExts.MaxPoint.Y); //Track the objects created for each column

Is there a way to select objects within a closed polyline? I thought there was but I can't remember how to do it.

I need a lisp that can remove all objects (lines, polylines, blocks etc.) outside of a polyline. polyline is closed and shape is variable, so not rectangle.

Im practicing for my CAD certification test and im trying to select all objects inclosed in a poly line. Right now i have a bunch of random circles and a random figure drawn in the middle of a bunch of circles. How do i select ONLY the circles that are completely in the object?
P.S. I would add a picture but i don't know how to take a screenshot on windows xp.

I need to have a table that updates when I change the length of a polyline, These lines are split up into segments for different types of materials. We usually add this up manually but would like to find a solution that is a little more automated.
I have mostly a background in GIS and have excellent knowledge of Autocad Map. I came up with a solution by creating a shapefile and making a multi-part feature for the segments. I added a table and connected to the .dbf file of the shapefile. I then calculate out the lengths of the line and update the attribution of the shapefile. Easy and took a few minutes to do.
I just want to know if there is a better way of doing this. I have did some searching and have found some information about alignment tables.

STEPS: Group > Select Ojbects
PROBLEM: When I go to select the objects as as a SINGLE OBJECT, each object within the group is selectable -- as if they were not grouped.Shouldn't it be that when I select ANY of the objects within the group ALL OBJECTS in the group get selected, and not just each object?

I have drawings with a lot of polyline objects. I need a routine which will draw multilines by coordinates of vertexes of this polylines. For example, if there is a pline with coordinates 10,10 - 20,20 i want to draw in other layer MLINE with the same coordinates. I know it's should be simple but can not gues how to do it. I've never used LISP before.

I have a series of Autocad Objects (3D faces). I need to turn the contiguous group of them into a SINGLE Autocad surface. I know next to nothing about vanilla autocad and 3D stuff. Seems there must be a way to make a surface out of objects. I would then use this resulting surface to carve a solid. DWG with 3D faces in it attached.

Is this possible? The problem with the express tools is that they place these single line text objects into one MLtext which is not what I want.

There is a major bug with CorelCAD LOFT command - when used with 3D polyline objects, it fails and errors out with the following error:
Specify cross-sections in lofting order»1 found, 2 totalSpecify cross-sections in lofting order»Selected cross-section is not a valid type.
The workaround is to set the CCS to the plane of the 3D polyline object and then use 2D polylines to recreate it, move the 2D version, delete the 3D version, Align the 2D version with where the 3D version came from and then repeat the LOFT command.
Has been logged with Graebert under ticket: #12458
To repeat the error, see the test file. There are two radially aligned triangles in each set. The set on the left are 3D polyline. The set on the right are 2D polyline. Attempting to loft the set on the left will cause the error.
Both large and small triangles are respectively co-planar.

I have a question that involves texturing multi objects for a single model.
1 - should I texture the peices first and then attach them together
or
2 - should i attach the pieces together and then texture them.
Also, once the model are attached, should I still weld the vertices and if I dont weld them, will it affect the animation when I rig the model?

how to take a normal image ( / alt. link say this one for example) and take it to something like this.
I have no idea how it happened but I'm supposed to replicate the image effect for an update using the first (normal) image.
currently using Photoshop CS3, if it helps.

After clicking on a keyword in the Keyword List to filter my results, how do you remove that filter to go back to where it was before? I can click on another keyword or I can choose Previous Import under Catalog, though is there another way to remove the most recent keyword filter? A keyboard shortcut?

I created a text using the "chip away" filter and really liked the way it looked. Then I wanted to glowing hot filter to add some cracks into the text, to make it look like lava was coming out of it, but every time .
I try this the background turns completely white, or the text just becomes "glowing hot" and the "chip away" filter disappears.

I use a canon 5D Mk3 and a Sony nex 5. On both cameras, at import time, I am likely to have both movie files and still RAW files. I do not import my movie files into Lightroom, I import them into Final Cut Pro X, but I cannot find where in Lightroom I filter the import. At the moment I am having to painstakingly go through the import thumbnails and untick the movie files, which is tedious and prone to error (I missed importing an important RAW file the other day by unticking it by mistake. Lightroom is so professional and quick to use with its presets and customization.

I am archiving numerous historic photographs by scanning the originals as high-resolution TIFF files. I need to rotate the scanned images slightly in Photoshop for presentation/archiving purposes but I am worried about losing some image quality.
To maintain loss less images, is it necessary to open my TIFF images as "Smart Objects" before rotating them? If so, this increases my file size many-fold on saving. Is there a way to maintain the approximate size of my original TIFF file? I am working in Photoshop CS4, Windows 7 64-bit.

I've been exploring migrating my Design and PrePress departments away from Illustrator & Flexi and transitioning to Corel. Unfortunately I've hit a major stumbling block
Right now I have a team of designers laying out sign designs. They draw each sign and we generate a message schedule for those signs in excel. From there, we've been able to use the print merge function in Corel to transfer all the messages from the data sheet to the signs. The problem is, each sign is placed on a separate page within the Corel file. I know you can then use print imposition to gang those signs for printing...but the problem is we have a laser engraver, rotary engravers and routers that are all being run. I've fairly certain we could "print" to the laser without any issues but I'm not as confident regarding the other machines.
Typically once we have the drawings of every sign created (currently doing this in Flexi), we have programmers that gang all similar components together on files that are used to power the rotary engravers. Because the print merge function in Corel puts each sign on a separate page, I'm not sure how we'd be able to transition without having to copy, paste and place each sign back on to a single page. Our jobs often run into the hundreds of signs so the extra labor required would kill any savings such a transition might bring us.
Is there a way to combine pages post print-merge, to get all the objects on a single page? I had really hoped to be able to gang all objects together on a single page within a single file.

Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?

Due to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.

I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.

Is there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??
I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.
