AutoCAD Map 3D :: Anyway To Lock Direction Of Polylines
Aug 16, 2011
Is there anyway to lock the direction of polylines? I have several drawings with diversion ditches. I use the linetype to show the direction of flow but antime I have to change ltscale or linetype, it reverses the direction. This can be an easily overlooked situation and a time consuming one to correct.
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 have cut several sections at different points along a road alignment. The sections are cut facing the same direction as the alignmnet. Is there a way to reverse the section direction without changing the alignment direction?
As the above mentioned, I have a drawing drawn using polylines with width from someone. The width of the line are suppose to represent area,
To put things into prospective, here is an example:
The polyline is 10 unit long and with a width of 2 unit wide. If i explode that polyline, it will become a single polyline without width. The line are suppose to represent 10 unit long and 2 unit wide; representing an area.
My question is is there a way to change the line above directly from polyline with width to a close polyline (4 x polylines) of 10 unit long and 2 unit wide.
I have a drawing of a stone railing section and I have to change direction in the run direction of the baluster panel. Is there a way that I can move the details without changing th Y direction of the details. Please refer to the attached CAD file for details. I am trying to avoid having to redesign the panels if possible. railing detail.dwg
Is there a way of converting 3d polylines to polylines with an elevation?
I have a dwg of contour information, the contours are 3d polylines, because they are contours the z value is constant all along the line, so there no question what the elevation of the polyline would need to be.
I need to do this as I then need to import the dwg into a GIS programme called MapInfo whch doesn't read 3d polylines.
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.
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?
I keep needing to Flatten everything in my 2-D drawing (actually, since ExpressTools isn't installed, I have to manually change the Elevation to 0),
but it seems there has to be a way to get AutoCAD to "lock" a DWG into 2-D, or Z=0? My lines keep accidentally getting Z-values and it's really annoying...
How to make a type of material go in one direction or by another degree . Ex: if you click on a wood type material, it goes up or down and right or left depending which side of that object is. On the picture below, it goes up and down, side to side no all sides go in one direction. I need to know how to mange the direction of the way of where the material go.
I just upgraded to AutoCAD Lt 2012. In the settings, I was able to figure out how to automatically get a landing line and how long I want it to be. But! When I draw the leader to left of center, it puts the landing on the left side of the line. How can I turn that auto-directional thing off?
is 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.
Over the past year I have been working on quickly generating vertical cross sections through 2D lines. I have exhausted all of my connections with fellow AutoCAD users and I still haven't found an efficient solution.
The material I'm working with is a bunch of polylines that kind of resemble branching tree roots from dozens of trees. The polylines sprout from seed points and then branch and cross each other as they move down. I need to generate many vertical sections through the lines. Since the material is composed of lines a slice along a plane would only generate points. I need to take a slice of a volume of lines so that the paths are preserved.
I have tried creating two vertical parallel planes and then using the slice tool on each plane. This would break up all of the polylines at the intersection with the planes so I can manually delete all segments that are not between the planes. This is time consuming, and also leaves room for error when manually deleting line segments.
The ideal tool for efficiency and accuracy would be Section Line. I could create a section line, convert it to a volume, and generate a 3D section with the option to save the section to a new file. The problem with this is that the section tool only works on solid 3D objects. I have considered sweeping a small diameter circle along each polyline to give them volume, but this would take days to weeks of work.
Is there a better tool or method for creating 3D sections of a volume of polylines? Are there any tricks that can be used to allow the 3D section tool to work with the polylines? Maybe I could convert them to a different type of object.
I have a drawing that is a topigraphical survey in 2D its constructed of 2D polylines, I need to convert these to 3D polylines so I can add a Z vertex then move the lines/contours to their Z value currently illistrated by text on the plines.
change the line types and easily move the lines to their correct Z value?
I am having a problem with Autocad12 I am using at a friends office: we both can open, edit, and save the same drawing. This is a real problem as you can imagine. We are running Windows 7 and are using DROPBOX for file storage. DWL are being created but for some reason they are not being used. On the otherhand if I try to open a file I created I do actually get locked out - just not from the other computer.
Just did a test - when I log in directly to the hard drive instead of the network it locks me out if I attempt to load it. If I login through DROPBOX it does not.
how I can have autocad recognize the lock files in DROPBOX folders?
So I have a viewport, viewing exactly what i want it to in model space but it's not where i want it in paper space. When i move the viewport entity in paper space it's changing my view in model space. How do I lock what the viewport is seeing?
I've tried locking, that doesn't seem to do it. I've tried yelling at it and that's not working. I'd try beating it with a stick but I don't know if the computer could handle it.
I am in 2D mode in autocad, drawing a plan. I have locked one layer and also increased the translucency, jet my snaps still respond to the objects in this layer, where all I want to do is keep it as an underlay while I draw the rest of the things. The objects within this locked layer are also selectable, they come up with doted lines once selected, but I can't edit or move them, because the layer is is locked.
Is there a way to lock the layer, so that it is completely ignored by snaps and selection, jet kept visible with little transparency?
I am using AutoCad 2013, and there are only blocks within this layer.
I have made line types with text and need to reverse the direction that the text reads. The text autocorrects based on UCS north. The UCS in the drawing is rotated 90 degrees so line text reads upside down. I type in the reverse command but the text does not change.
I have a polyline that meets itself back at the beginning. It should be closed and appears to be. I joined several lines to get the polyline. When I try to offset it I can only offset towards the inside and not the outside. Is there a reason for this or am I doing something wrong?
I have a circle that I would like to move ‘Z’ direction along the Current UCS. The Current UCS can be in any 3d plane.The code that I have only moves the circle 5 units up along the WCS.

When I create a line label, one of the components available is “Direction Arrow”. This component is not available for “Curve” labels. I would really like to use C3D labels to indicate direction (I realize curves don't have a 'direction', but I don’t mind manually flipping and reversing the arrow). Is there any other label option in C3D that will draw a direction arrow for curves?
