AutoCAD Civil 3D :: Perpendicular Line From Point Laying On A Line / Pline
Sep 30, 2013
I have a line or a pline segment and i want to start a line from a point laying there and go perpendicular outwards. Is there a way to do it with tracking?
Yes, i saw the command draw line at an angle but i find it a little bit complicated for a simple task like that. I am sure autodesk have a simplest solution about that.
If i am already at the draw line mode and i can easy catch the tracking perpendicular to previous segment but if i want to start from another line and go perpendicular i cannot make the tracking work.
How to draw a line perpendicular on an arc at the a particular point?
I wanted to draw a line perpendicular to an arc at a particular point but couldn’t approach it. In this case, I need two snaps to work at the same time! To be perpendicular on the curve and at the same time to be snapped to the point!
How do I draw perpendicular from a line or object at a specific point? I know by holding shift and osnap perpendicular I can draw the line but I can not osnap to the exact point!
I have a curved path I imported into Illustrator, and I'd like to draw a line perpendicular to the curve at a particular point. I've searched google and this forum, but can't find any description of how to do it. Corel Draw has a button that lets you do this, so I'm hoping something similar exists in Illustrator...
i'm currently just calculating the angle at the point I want using the derivative, finding the angle, and then adding 90 degrees to it. But I need the line to be placed at a particular point, and the X/Y properties of the line are based on the ruler which isn't even in the center of the document (I want to position it relative to the artboard). As in, I just want to set the position of one endpoint of the line...
Is there a simple way for drawing lines or plines perpendicular off a given line which is not horizontal or perpendicular itself?

Is there a way for drawing that yellow line in the drawing with a given length directly off the ending of the white line? Without using SNAPANG or the like?
I have installed version 3.5.10 and I am working on a project where I need to overlay gridlines onto a photo. I have tried using the gridline feature, but that does not work, and I have watched a video tutorial which has good information but the tutorial was for version 3.5.8. The features that were in the tutorial seem not to be available to me with the version that I am using.
what is the setting to tell a line to extend to the face of a pline when that line doesn't actually intersect with the pline? see image below...line 1 will extend to pline faces A and B, but how do i get line 2 to extend to those faces? i know this worked when i used autocad 2008 but i'm now using 2012 LT so hopefully it still works, i just don't remember the command name to control it.
Recently I've been working with a lot more projects that contain curved architectural features. It appears that I am unable to draw a line to an implied perpendicular point on an arc. I can draw a line to an implied point perpendicular to another line but not an arc. refer to attached images.
Image1 demonstrates the implied point perpendicular to a line.
Image2 demonstrates that there is no implied perpendiuclar point on the arc given by AutoCAD.
Image3 demonstrates that if the arc is manually extended, a point perpendicular to the arc does exist.
I am trying to make a circle perpendicular (at its midpoint) to the end of a cylindrical helix in 3D space. I tried using the perpendicular geometric constraint but it won't let me (says "invalid selection"...). Is there a way to make the ucs (z axis) tangential to the end of the helix?
Now I have all block instances rounded into a 5mm-accuracy. How to also round in Line start and end points (and maybe even polyline vertices) into a 1mm (or custom) accuracy. There are hundreds of inaccurate line elements within the drawing .
I am trying to create surface elevation labels along a polyline and I am having an issue with the label anchor point. I have created a line label style that uses a reference text to produce the elevation from a specified surface, however when I insert the label the default anchor point for the label is in the center of the line segment and that is where the reference text is taking the surface elevation. I am looking for the elevation of the surface at the start of each line segment, and I do not know how I can make it stop defaulting to the center of the line segment.
Attached is an overview of what my labels look like, where the anchor point is, and the layout properties within my label style. I am using C3D 2012.
Is there a way to have a multiline point description? For example, in the raw description, i wrote out the text, but I would like to return a line for the parentheses.

Is there a way to convert a feature line elevation point to PI?
My objective here is to delete all the elevation points except one. It would be time consuming to pick each elevation point and delete them individually (in this case there are about 15 but sometimes there are more). I want to use the delete all option but keep one one of them. If I can convert that one into a PI I could then quickly delete the remaining elevation points.
How shall I draw lines into a created surface using raw or full description of ascii file format(COGO)
for example in the imported file i have points to describe a road center line(CL),or edge of the road(ERD),breaklines(BRKL) and want lines represented by the descriptions to be drawed in the surface so that i can use the lines as guides in profiles design.I didn't want to use point number which are not serially ,and have tried to use point grouping without any success
Is there any way to increase the size of the marker that shows up on the plan view when you select a PI in the elevation editor? It is so small that if I have the feature line selected I can't see the marker over the highlighted line. I generally have to zoom to a PI so I can see where I am.
I'm working on a stream restoration project and we need to determine the x coordinates and corresponding elevations along a stream alignment at certain sample lines. The centerline of the stream's alignment has been created as well as sample lines for cross sections at 50' intervals. We need the coordinates & elevations of each sample line (cross section) exported into an excel/txt document.
For instance, at station 1+00 of the alignment we have a sample line. We need to know to the right and left along that sample line the corresponding elevations and that x coordinate) from the alignment. Primarily, whole contour intervals but more information would be useful as well. I was hoping this could be automatically generated.
I want to set and Elevation Point (not a PI Point) along a feature line by entering the grade from the previous point. Currently the "Set Elevation Point" command only allows entering an elevations or getting an elevation from the surface. I know I can set an elevation point and then use the "quick elevation editor" to adjust the grade, but I don't want to go through the extra step.
The command for Creating Lines by Specifying a Range of Point Numbers makes 3D line segments. Is there an option to make a zero elevation polyline running through cogo points that are 3D (the 3D line segments occur even if the cogo points are set to flatten elevation)?
At center line I want to place a small perpendicular line in specific length and put their coordinate to excel sheet(export coordinates).
I have already two programs for this, one for placing objects on curve with specific length and 2nd for pick & export coordinates to excel or other type of file. but this is very lengthy process & need too big time. but I think it cab be done in a single command written in lisp.
I think this issue started with SP2. I don't remember having these issues in SP1 and earlier.
Create some COGO points at varying elevations.Start a new feature line.Use "node" object snap and pick your first cogo pointIt does not pick up the elevation of the point (it used to)Now draw feature line segments to a few more cogo points entering the elevation each time.It does not pick up the elevation of the point (it used to)Now switch to Arc mode and snap to a few more cogo points.It does correctly picks up the elevation of the cogo points (like it used to)R.K.

I am looking to draw my pipe with a thicker appearance than the typical line of width "0". Our storm pipes are usually drawn with this so as to stand out from other utilities. If the pipe is represented by a polyline, I have usually adjusted the "Width" or "Global Width" value to my liking. With pipe objects, it seems more complicated. I have searched the settings, and the closest thing that I could find was the Lineweight property, but that appears to have no effect on the line thickness in the CAD drawing.
Do I need to tweak a plot setting? Make a new linetype altogether?
I needed to remove a feature line that I used as a break line when creating a surface. When I removed the feature line from the definition of the surface, the grading did not change. It appears the points created by the feature line remain which is why grading didn't change. The only work around was to delete these points.
I noticed the same thing happens when I removed the surface boundary and inserted a new boundary. why these points remain and how to remove when I delete boundary and feature line from surface?
