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 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.
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.

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 want to dimension along a curvy polyline. I don't want to station it like a centerline. It is for pavement marking dimensions in a curvy road and I want to show the total length of turn lane lines while they go through an s-surve. I could draw the dimensions manually and have in the past. For the contractor, I would simply station and offset it, but it makes it easier for the reviewer to see total turn lane, taper and lane shift lengths, rather than having to calculate them from station and offset callouts.

Recently my company has changed the standards to label existing utilities with text right above the utilitie lines without leaders. I would like to do automate this process somehow using attributes or something similar to that. I have attached a screen shot of how I would like it to look. The objective is to speed up the labeling process.

I have a problem iterating heights when making a polyline between two different points that have Z-values. I've used Autocad Civil 3D for working with geodetic data with height measurements before and I remember using geodetically measured height values, transforming them into a surface and then when I create a 3Dpolyline within this area the polyline automatically gets z-values that change along the line.
In other words, I could use this 3Dpolyline to obtain a profile that gives me z-values even where there is no exact point with a value has been physically measured. It was a while ago I worked with Autocad and now when I started again I have a similar problem but can't manage to create a surface and get iterated values.
My exact problem this time is:
I have a sewage pipe that runs for several kilometers that is drawn as a 3Dpolyline, with correct x- and y-values. It doesn't have any z-values yet and these are what I want to obtain. I want the polyline to have continuous z-values that changes along the polyline (not only in vertexes) so that a smooth profile can be drawn if wanted. I have data of measured actual z-values for approximately every 500 meters or so along the sewage pipe and these are currently drawn as 3Dpolylines of around 20 meters going perpendicular to the pipe (as in the picture). In other words there are bars with z-values crossing the pipe all along the stretch. Now, what I want to do is to somehow make the polyline that represent the pipe to get the heights from these perpendicular bars with the measured z-values. If I try to draw a new 3Dpolyline between two of the measured bars where the actual pipe is supposed to be, the end vertexes of the 3Dpolyline gets the z-values of the bars. However, the value in between the bars gets the Z-value 0. So, if I start a 3Dpoly on bar 1 then continue the pipe with another vertex, and then finish off at the second bar I will have 2 vertexes with the correct z-value but the middle vertex will be incorrect (0). How do I get the pipe to get the correct z values automatically iterated from the values on the crossing bars? Is this even possible to do? Should I create a surface from the bars first, and in that case how do I do that? If possible I don't only want the vertexes between bars to have iterated z-values, I also want the entire line to have a correct value.
I've attached a crappy image made in paint (since I don't have Autocad on my home PC, only at the office). And just to make things even clearer I'll give an example. Let's say the pipe distance from 1 to 2 is 10 meters, the distance between 1 to 3 is 30 meters and the z-values of bar A and bar B is 10 and 25 respectively. So, when I draw a 3Dpolyline from 1 to 4, I want the vertex 2 to automatically get z-value 15 (since it's 1/3 on the way to B). In the same way, I would like for example the point on the pipe that is right in between 2 and 3 to have the z-value 20. I won't mind redoing the bars to for example singular points instead, if that makes it all easier.
