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.
Drawing: line, arc, line.
arc was defined with line's end points and radius, so I'm positive that this drawing is continuous.
Steps I take:
pedit
click

I had no problem turning other arcs into polyline...
I need to join multiple lines to a new polyline..The lines are filtered by a selectionset
Dim oPline as new Polyline()
For Each oSel As SelectedObject In acSSet
Dim oEnt As Entity = TryCast(acTrans.GetObject(oSel.ObjectId, OpenMode.ForRead, True), Entity)
oPline.JoinEntity(oEnt)
End If
Next
The error occurs on the oPline.JoinEntity(oEnt)
So the problem I am having is when I try join lines and/or make a polyline. I am trying to model an electron lens and have all the measurement and angles correct but Autocad does not want to allow me to join the lines so that I can make a 3D model for export. When it does allow me to join all the line or make a polyline, the lines are not straight. Granted I have to zoom in to see the deviation in the line but my connecting lines are not orthogonal like they should be. Here is a picture of what I am trying to make.
The main problem area is the gray part three electrode 1.2.pdf (Don't know if you can see my attachment)

How do I solve this problem I cannot join basic lines to make a closed polyline as they will not join together. So i tried to use the flatten command which does not work and out puts error below:-
Command Prompt Input/ouput
Command: FLATTEN

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.
I have an existing polyline of approximately 5'. When I choose PEDIT where do I go from there to make the plolyline exactly 12'8"? I'm in architectural mode. Ooops, I forgot to say this is in DraftSight, which should be similar to AutoCAD.

View 5 Replies View RelatedAny 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 2 Replies View RelatedUsing VB.NET, how to create a new polyline out of existing lines and arcs? I am converting existing VBA code into VB.NET, developing in AutoCAD 2010 using VS Professional and I just stumbled into this road block.
Without using programming code, this task can be accomplished via AutoCAD command by typing the PE command, selecting the JOIN option and then selecting any lines or arcs which should be combined to form a polyline.
Using programming code, however, I am quite stumped on this task. I have been able to successfully create the lines and arcs which should form the polyline, and they are all connected as well so they would form a connected polyline; I simply do not know how to proceed from here.
I have a proposed surface that has been made by selection polyline with a z elevation as contours. Is it possible to have civil 3d easily change the weeding and supplementing factors to a tighter value after it has already been made?

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.

The points are not lined up with any standard axes, but do have a common plane. I would like to create a polyline using the points above. I have tryed playing with 'polyline3d' and 'transformBy' but could not get it to work.
The 3d poly would be in an xref, and for my purposes i don't need it to be a 3d poly. Can this type of object be cloned? Or would it be better to collect the vertex points and create a 2d poly on top of it?
