AutoCAD Map 3D :: How To Add Direction Arrow To Polyline Features In SHP File
Mar 9, 2011
I 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)!

why doesn't the arrow leader disappear when I flip my arrow direction to the inside..

Now, in my understanding, the flow arrow should either be rotated 0, or 180 (pi radians). But clearly, some of them like to have their own mind about things, and decide on some other rotation. It seems that on the steep slopes, the arrows go a bit skew.
I think the skew is related to the actual elevation difference of the segment, rather than the steepness of the slope. A long segment with 15% slope has a worse skew than a short segment at over 30%, presumably because the elevation difference from the start to the end of the segment is larger.

I can't seem to find where to increase the flow direction arrow size on a watershed. Am accessing remotely, it's a bit laggy and bothersome, but doable. I looked all over Toolspace.

I'm having trouble merging paths. I'm combining the multiple paths with arrows to make the 3D effect (which is on all of them obviously) flow as one instead of on top of eachother. When I use the compound path command it reverses all my arrows and I have no way of changing them back without releasing the compound path (which puts them back to their original state of being on top of eachother)

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'm using DP7, and working on a logo with 3 different shapes. They all have bevels applied to them (applied at different times and angles). I like having the light angle direction arrow to drag around to see the different effects from different angles but the arrow isn't always visible. What do I need to do to keep it visible, or make it visible? If I hit Ctl+B or Ctl+F the arrow will appear but the selected object will also move to the front or back at the same time. I've tried selecting the object first, then the bevel icon, and sometimes that works and sometimes not, although the outer bevel arrows will be visible. Even when the rotation arrow isn't visible I can change the light angle with the slider but I would prefer the rotational arrow instead.

I want to draw triangle in segment of polyline in segment direction.
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

I've got GIS shape files for sanitary sewer pipes and manholes which contains object data for the upstream and downstream inverts on each pipe as well as the lowest invert at each manhole. Ideally, I would like to add an arrow to the pipe showing the flow direction in the sewer. i know I can use the annotation template to label the inverts, but is there a way to automate the process to add the direction arrow?

I 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.
Is there a key combination for that (Mac OS)?

In my map book template 8.5 x 11 Elegant file when I inset it in a mapbook the adjacent arrows are underneath the block I have to go to the template right click go to draw order and pick send to front. I went to the template file went to block editor to make these same changes there and had no effect.

I am using inventor 2013 and creating the drawing for a part or assy. and saving it to autocad 2000. after i open the saven .dwg fine in autocad 2000 of customised .dwg viewer (EDMS internal customised vault kind of software), i see some of the features of annotations and even mechanical features added has question mark (as the images attached).
Thing is what i am doing is and we have a BOB.shx file for the font. (which inventor is not supporting) and we could not bring this inside inventor. Inventor supports only .ttf font types.
So how way possible we can use inventor drawing inside autocad 2000 by save a copy as option. or you have any patch type support.We are loosing lot of time in this as a productivity loss.

I'm using Inventor 2014.
I created a Punch Tool iFeature, everything seemed fine, I could save it without problems.
However, when I try to place it in a part with the Punch Tool, it says "The file has 0 volume changing features. To be a valid punch tool, the .ide file must contain at least 1 sketch-based feature."

I am able to export to SDF but I get nothing when trying to go the two shp formats available. was a "parcel", but i exploded to polyline.
Do i need a patch to make this work? I am a C3D newbie and am struggling wit h user interface, but know that map export command line looks like it is supposed to work.

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.
