View 9 RepliesIs 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 6 Replies View RelatedI need the features shown in a connected SHP file to display an arrow indicating their direction (i.e. -----> or ----->-----). This seem that it would be important to anyone using Map for municipal engineering (sewers tend to be directional!), drainage (so are culverts!), etc..The difficulty in doing this simple task is just adding to my hatred of Map (especially given the amount of money I've spent on Autodesk products)!

I have a linetype
*DIVERSION_LARGE,diversion large ---- >> ---- >> ---- >> ----
A,.5,-.2,["<<",standard,S=.15,r=0,U=0.0,X=-0.1,Y=-.05],-.2
when I draw a polyline, or use it as the linetype in a feature line style, the arrows seem to revrse whenever there is a change in direction any significance. Also, the reverse command and reversefeature command have no effect. Rotating a segment does not change the direction. I know I must be missing something.
In the attached, I have a feature line, and a polyline that the arrows change direction when the feature does.

I am trying to create a new linetype using arrows to show the direction of a flow. I can get the outline of my arrow head to save as a shape, but have not figured out how to save the hatching to show up in a linetype. I need the arrow head to be shaded in solid. Also is there any downloadable linetypes out there for Civil 3D?

I have target segment and center point of it:
Polyline line = ...
LineSegment3d centerSegment = line.GetLineSegmentAt(centerSegmentIndex);
Point3d centerPosition = centerSegment.MidPoint;
I can find direction of this segment:
Vector3d zaDirection = line.GetLineSegmentAt(centerSegmentIndex).Direction;
Next, I create list of points:
List<Point3d> points = new List<Point3d>();
points.Add(centerPosition);
points.Add(centerPosition.Add(new Vector3d(ZASize, +ZASize, 0)));
points.Add(centerPosition.Add(new Vector3d(ZASize, -ZASize, 0)));
And draw it:
wd.Geometry.Polygon(new Point3dCollection(points.ToArray()));
Ok, I have triangle but... it's not in segment direction, it's X-direction.
I try to rotate it:
points.Add(centerPosition.Add(new Vector3d(ZASize, +ZASize, 0)).RotateBy(0, zaDirection, centerPosition));
But it's not the same as I want.
How I can draw triangle by serment direction?

I have created a linetype with the text GAS OPTION in it. The line is continuous with a break around the text. In a straight line the linetype works fine (breaks around the text etc). However, when I use a polyline and spline the line for a curved line the text aligns with the direction of the line at the start, but when the line bends, the text suddenly changes direction and reads in the opposite direction. It looks like AutoCAD is trying to keep the text upright rather than following the direction of the line. When the text changes direction it also changes its insertion point and overlaps the continuous part of the line. I have 2013 AutoCAD.
Here is the string I used for the linetype.
*GAS_Option_LINE,Gas line ----GAS OPTION----GAS OPTION----GAS OPTION----
A,8,-15,["GAS OPTION",STANDARD,S=2.54,U=0.0,X=-2.35,Y=-1.27],-12

View 6 Replies View RelatedI have a path with a smooth point. The two direction points form a direction line with any non-45-degree-angle - say 11.8 degrees. I want to drag one direction point while keeping the angle of exactly 11.8 degrees.

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?
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 can't believe that in Acad 2006 there's no way to scale an object in one direction only e.g. in x direction scale = 1.15, in y direction scale unchanged i.e 1.0. Mstation does it - surely there must be at least a workaround in Acad?

View 9 Replies View Relatedis it possible to define a 'natural direction' at a pin, in which a wire should start when connected to that pin? This would seem to be natural for me.
As the attached picture shows, my wire is connected at this pin in a weird direction (because I need to route it through the indicated segment).
What is the best strategy to do it correctly?
Another question: I increased the diameter of the segment, hoping that it means that the wires are constrained within the segment, but are free to move withini this. But they all seem to be constrained to the centerline. What I want is that all my wires pass within this 'tube' of 30mm diameter.
