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
View 4 RepliesI'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.
View 3 Replies View RelatedI'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

View 2 Replies View RelatedI'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.
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?

View 4 Replies View RelatedDue 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.

View 5 Replies View RelatedIs 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.
Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.

View 9 Replies View RelatedI can do this in AutoCAD Map but I have my doubts. I will explain in ESRI GIS terms (this is what I am familiar with) and I hope you can tell me if I can do this in AutoCAD Map. In ESRI ArcMap I can select a line and I can hit a Select by Location button. In this window I can select all of the objects that intersect my selected line. Then I can delete them or export them etc.
In AutoCAD Map I have a polyline selected. It is my road centerline. I want to be able to select all of the other polylines that intersect my selected polyline. Is there a way to do this? I need to erase those polylines. Usually I will pan to each of them and select them individually. It just seems to take a lot of time. My AutoCAD co-worker said I could use a fence and draw the fence through my polylines. It seemed to work ok but I accidently deleted extra things that I needed. So I'm back to manually selecting each one by one unless you know a different way.

I need to get the values(textstrings) of some AutoCAD table cells into a string array, but I am having troubles. I have the proper table and I can get the contents of individual cells using acTable.Cells(1, 1).TextString, etc... but I cannot seem to remember how to get each cell value into an array.
See code below:
For Each acCell As Cell In acTable
If acCell.TextString > Nothing Then
strArray() = acCell.TextString 'Does not work
End IfNext
When I click on an array to edit it the contextual tab does not display. I am able to see other contextual tabs, just not this one.

Rhino allows for two-rail curves and extrusions, is there anything similar in Autocad2013? I'm working on a trellis that has an undulating, slatted top - I can array the slats along one spline/polycurve, but figuring out how to rotate them to match the secondary angle/curve (it twists) is proving to be really difficult. Rotate3D I have trouble with (crossing different faces/USC which confuses me), and doing so for each slat is going to be exceptionally time consuming.
Is there a way to array a form along two paths, so that the pieces automatically adjust to match the needed angles that both rails define?

I'm creating an array using a block from an existing dwg file on my drive. When i import this block on it's own, i can explode it to ownerspace with "bref.ExplodeToOwnerSpace();" but when i'm creating the array, i don't have this ability and i'm left with one of my blocks in the array exploded, and the rest not.

I'm trying to create an array from one block with the option to specify columns, rows, respective offsets as well as angle. The original block comes from a 98kb dmg and is pre-inserted at a specific x,y,z in the model space. The issue I run into is whenever i try to create an array with say more than 200 lines and 200 columns, the machine locks up. It generally will create the array however it can take upwards of 5 minutes.
