AutoCAD .NET :: Link Objects Of Array With Polyline
Jul 25, 2012
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

I'm curious if there is a way to array objects which are a set distance off of a polyline, along the polyline at a set distance on center. For instance having a circle a 1/2" off of of the polyline, and arraying that circle at 12" on center along the polyline.

I am trying to array a 3d block along a 3d polyline made up of straight plines. I align the block to the end of the endpoint on the 3d polyline ie the path. use array path command.The block does not align properly around the path. I have tried the z direction and selecting no.Attached is a drawing - the strange thing is that path works fine on the red pline but not on the cyan pline.3d Array.dwg

i have just spent 8 hours today trying to find a link that will vary target a poly line that i have set. i cant seem to find the link that will do what i need as per the attachemnt. the section between the edge of the foot path and the start of the fill/cut slope needs to be variable
i know how to set all the targets but this link seems to be a fixed length.

Im making an array of all the sketched symbol definitions in a drawing that are not used in the drawing as a sketched symbol..My problem is that i do not understand how to delete all the objects i have in my array at the end of the code
Dim oDoc As Drawingdocument = ThisDoc.DocumentDim oSkSymDefs As SketchedSymbolDefinitions = oDoc.SketchedsymbolDefinitionsDim oSkSymDef As SketchedSymbolDefinitionDim oSheets As Sheets = oDoc.SheetsDim oSheet As SheetDim oSkSymb As SketchedSymbolDim MyArrayList As New ArrayList
[code]....
So I got my array with all the objects to be deleted. But how to delete?I also believe this code could be a bit more efficient.

I'd like to set up a blockwith different attributes like Roomname, Floor, Area,...
Therefore I'd like to link a polyline of the drawing with the block and it shows me its area. I know how it works with fields, but not how to connect it when the field is within a block.
Is there a LISP for that?

It seems like this should be easy but it's not. I have a block with multiple components. I want them to array sequentially as I drag the grip. First one component, then the next, then the next. What I get is all 3 at once when I drag the grip far enough. I tried 3 separate linear parameters with their grips stacked but that didnt work either. What I have attached is a very simplified version of what I want, but I think once I get the concept it will be easy to elaborate on.

I'm currently creating blocks for our office library. One of these is a grille with some apposed blade dampers on it. I'm trying to set up an array that will duplicate the apposed blades as I change the length of the grille. However, it will only copy the blades in pairs, not singly one after the other. Ie, the blades are 100mm apart, and in a / pattern meaning that each instance of / or 'should' duplicate every 200mm. Except when I lengthen the block by 200mm it won't duplicate until I've gone double the distance (400) when it gives me both / and .

is there a way to create an associative array of posts so I only have to edit one part to have the entire array change? that is, I want to have global values for the dimensions in the picture below: post diametervertical width between post centreshorizontal width between post columns (again, centre to centre)vertical shift of each column w.r.t. previous one I've used the Rectangular Pattern tool to create a repetition of my posts, but I want to shift each column of posts up slightly with respect to the one before as in the attached picture:
It seems that if you want to repeat along non-perpendicular axes like this, Inventor fails if there are too many repeats. I came across this when searching the site:
[URL]
I can verify that this is my exact problem but can add that in my example, 4 repeats on the almost horizontal axis and 3 on the vertical work fine. However, 3 almost horizontal axis repeats by 4 vertical axis repeats will only work if I choose the vertical axis as Direction 2. (Is this a bug or am I trying to use the Rectangular Pattern Tool incorrectly?)
The repeat unit can be simplified to 1 circle with 2 construction lines along the repeat Direction instead of the 2x2 circles shown here but the problem persists. Also

Trick to keeping objects aligned with a helix when using an associative path array? The animation below demonstrates the problem where I can't seem to keep the "treads" on a spiral stairs aligned with the center of the helix. (fewer objects accentuate the problem)

how to control the draw order of objects created within an array in a dynamic block?
I have a wipeout, which works fine on the array source, but when the array produces babies, it places them infront of everything (which is only logical), making the wipeout useless.
Can I set array babies to have the same draw order as their parent?

I have a drawing file with block objects linked to an external MS Access database. Each record in the database was manually linked to a block object using the 'Link Records to Objects' found in Data View under the Links menu. As you know, this allows you to Auto Zoom to an object when you select a record from the Data View table.
The problem I am having now is the Auto Zoom doesn't work when you select a record from the Data View table and I am not sure why. I can perform a spatial query on an object and display the linked record from the Data View table.

I'm creating a roof in Max, I have made a shingle and applied the array tool to cover the area, now I want to apply a boolean on the entire roof to make a hole on it, however, I think It's necessary to join all the shingles into a single poly in order to allow the boolean operation. They are in a group at the moment and how to join the shingles other than converting them all to poly, making a selectable list and attaching the list to a shingle.

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'm trying to use the PATH array feature on 2013 to array stairs, and I can't get the array to be 100% accurate. It seems like CAD rounds the decimal to the nearest 3/4" which could be causing the problem.
I set my run to 10.5" and rise to 7.25", array along the angle of the stringer, and there's always a small overlap on the stairs. The "distance between" should be 1'-209/256" and CAD rounds it to 1'-3/4" which is where I believe the error is. Is there any way to fix this or array this correctly? Otherwise...back to the COPY method I suppose.

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.

I have an equipment list on excel 2013, that I can't insert into my AutoCad (2014) drawing. I've tried using paste special, paste link, using both as excel work book and as an autocad table. I have a wide variety of problems with both. Pasting as autocad table sometimes it wont update, when I try to update the link it locks up the drawing. When I paste as excel workbook it doesn't plot, although it show on plot preview. Is there a memory setting that has to be changed on autcad I have 12 gigs of memory on my computer.

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'm trying to find out if it is possible to link Smart objects to a psd file, mush as InDesign does with images. When they are edited they update automatically. If say a mock-up of a shop sign is created with the sign being placed from an original saved piece of artwork and changes are made to that artwork file and then saved over the previous, can the file update on the psd mock-up automatically as it would in Indesign?

how to link a biped's head to an object? I can link it to other objects as the parent, but I need the head to be the Child.
I'm trying to animate a Terminator robot model I found here (it was a free download):
[[URL]
The model is rigged to a biped, and I'm trying to animate its head to follow the exact movements of a person's head in some footage I shot. I used PFTrack to motion-track the person's head (using geometry tracking) and exported the track as a MaxScript. So I run the script in Max and it produces a camera and head model which exactly follows the movements of the original person.
how can I link the Terminator's head (or rather, the biped controlling the Terminator's head) to the animated model? Better yet, how do you link a biped's head to Any object? I can link any object TO the head, but I cannot make the biped's head the Child. How to do this? I also tried using Select IK Object in the Motion panel, which works for other parts of the biped, but not the head.

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'm rigging a character for use in Maya 2011, which I'm not all too familiar with - How would I link the blend shape states for 2 objects, so when I increase the value of one blend shape for one object, it increases the value for another blend shape for another object?
I have a blend shape for the mouth open position & I need the teeth & tongue open blends to match as the value increases.
In 3DS Max I'd use the reaction manager - is there something similar for Maya?

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.
