can I place a direction arrows on 3D polyline in dwg files? In 2D, it is very simple.
View 9 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 want to scale a polyline representation of a foil along one axis only, so that it becomes longer and thinner. Is there a way to do this .

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.

Any way to move objects in vertical direction (z-axis) in 3d views, without having to turn the view everytime to be of frontal direction. I would like to move entire objects - for example mass objects - up or down directly in a 3d view of random orientation, now only top- or bottom face can be moved vertically, the whole object moves only on xy -plane. Can vertical movement of an object be done intuitively graphically and/or can it be be numerically, feeding coordinates?
Have tried all sources, but cannot find solution, and refuse to believe that Revit would be the only 3d/bim software on planet where direct vertical manipulation of objects is not possible.
I draw a closed polyline and then I extrude it. But when I want to see the 2d plane and hide the 3d version I cannot go back as the polylines are extruded and everything is disappearing. Should I draw a second poly over the first, then create a new layer, name it for example 3dpolywalls ? Is this the most common technique? Or there is a more efficient way ?

I.e. every time you open a new sketch the corresponding lateral and vertical axis will be projected onto the sketch.
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 am trying to set up the bulge for a polyline, in order to set up the bulge currecty I need to know if the polyline was created clockwise or counterclockwise.
View 4 Replies View RelatedI 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.

View 6 Replies View Relatedi try to make an animation. I create a cylinder and i want to rotate it by longitudinal axis. i click 'components', select the cylinder and after i click 'position' to select the axis that axis system appears in the right side of the cylinder not in the middle. If i continue whit this settings the cylinder will rotate by a circle not by his longitudinal axis. How can i move that axis sistem in the middle of the cylinder? I can drag it but can't place it exactly in the middle.

View 9 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.
Is there a key combination for that (Mac OS)?
I'm rigging a shoulder pad to a biped and I'd like it to only rotate on one axis. Google hasn't been that useful, and I hope I don't need scripting for this kind of minor thing. I'm rather new to 3Ds Max Design but I'm learning fast and liking it so far!
I've attached what I want to effectively accomplish. I'm looking for a way to lock the z-axis of the object with the upper arm's z-axis.
EDIT: Reduced picture size.
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 6 Replies View RelatedI 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.
I want to convert a 3D polyline to 2D polyline.
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.
How do you find 'if' a polyline is inside another polyline?
