AutoCAD Civil 3D :: How To Create Reverse Curve With Straight Portion In Between
Aug 5, 2013
how to create reverse curve with straight portion in between , as their is no option of creating reverse curve with straight portion in civil 3d , duding designing a hill road what ever the reverse curve you design will be wrong and superelevation generated will also be wrong as it do no include straight in between the curves (ie reverse curve should contain transition curve transition straight transition curve transition.)

I need to put a reverse curve on an alignment. I have tried using two free curve fillets,(between two entities, radius). the first curve was fine, but it would not allow the second curve. I also tried using a floating curve ( from entity radius through point) first, but it did not work.

I have edited the "GeneralLegalPhrasings.xml" file used for the parcel report "General_Legal_Description_for_Parcels".
Two issues: 1. it will not label a reverse curve properly....it shows them all as "compound curves". 2. A curve to curve is always shown as "NonTangent".
I've attached the .xml file (I only edited the imperial parcels - the second large group of <Metes>).
Quite simply, these two "types" below have the words "reverse curve" and tangent or non-tangent accordingly in the output phrase, but it only creates non-tangent compound reports.
Curve to TangentReverseCurve
Curve to NonTangentReverseCurve
This is the report from the parcel in the attached dwg file (notice the "curve to the left" -> "curve to the right" labelled as compound, and all non-tangent curve to curve):
From the POINT OF BEGINNING; Thence, North 90° 00' 00" West, 129.16 feet to a point for corner;
Thence, North 00° 00' 00" East, 100.00 feet to a point for corner, the beginning of a curve; tangent
Thence, 61.46 feet along the arc of a ____ curve to the right, having a radius of 39.13 feet, a central angle of 90° 00' 00", and a chord which bears North 45° 00' 00" East, 55.34 feet, to a point for corner, the beginning of a compound curve; non-tangent
Thence, 47.09 feet along the arc of a ____ curve to the left, having a radius of 29.98 feet, a central angle of 90° 00' 00", and a chord which bears North 45° 00' 00" East, 42.40 feet, to a point for corner, the beginning of a compound curve; non-tangent
Thence, 94.33 feet along the arc of a ____ curve to the right, having a radius of 30.03 feet, a central angle of 180° 00' 00", and a chord which bears North 90° 00' 00" East, 60.05 feet, to a point for corner;
Thence South 00° 00' 00" West, 169.11 feet to the POINT OF BEGINNING and containing 0.483 acres of land.

I am trying to create a subassembly with a curve in it. See attached .pkt and .dwg files. Very small and simple.
When I attach the Subassembly to the Assembly, the event viewer shows "[Something wrong with current subassembly: The given key was not present in the dictionary.] (Source:Subassembly.Subassembly1)"
The link that represents the curve does not display; only the tesselated points display. In the Subassembly Composer the curve does display.
The file called curved.zip needs to be renamed to curved.pkt. This forum does not allow attachment of files with pkt extension.

I am receiving an invalid input message when trying to create a curve between two lines. My drawing units are set to architectural. The problem is summarized as follows:
1- In Lines/Curves menu, select curve between two lines.
2-Select first tangent
3- Select second tangent
4-Select radius option
5- Enter 8'6"
6- After entering the radius I receive an invalid input message.
7- But if I enter the radius as 102 (102 inches) the curve is created without any problem.

I cannot work out how to consistently go from drawing a straight line to drawing a curve and then back again to a straight line....
The first two steps are fine, but when I go to the third step of trying to draw a straight line after a curve I am having problems, it does not seem to be consistent - I click on the last node which then displays the line next to the pen but if I try to click for a straight line - it makes a curve!
If I use the Alt key and click the node, this also sometimes works but not always and I can't for the life of me work out a way to get it to work in the same way all the time.

I applied a 1pt stroke as you see in the screenshot and I gave it a default width profile. For some odd reason no matter what I do that stroke has sharp edges and isn't curved smoothly.

In PSCS5 and earlier, I used to be able to make a straight line of points in a curve by placing 9 points on the straight line curve. I did this by drawing a small straight line at the bottom of the curve using the pencil tool and then clicking the curve point icon.
I can't seem to do this with CS6.

In CS5 and prior versions of PS, you could "make a straight line of points in a curve". After opening the curve dialog box, draw a straight line with the pencil tool and then click the wavy icon above the pencil tool icon (edit points to modify the curve) and it would automatically place 9 equidistant points on the curve. With CS6, it only places 3 points. Any way to get 9(or at least multiple) points placed?

Say I have a square or a polygon. I want to transform one of the sides from straight to a smooth curve. Is there a way to do this?
I have the pen tool and I'm tracing an object. I want to create one curved side then continue on with straight edges. However the tool insists on creating 2 or 3 curves at a time.
Is there a way to create a single isolated or part of a shape curve thats adjustable with both endpoints. It seems that curves I create often are missing adjustment levers at one of their endpoints making it harder to get the shape I want.

I have ran an analysis and SSA gave me Error 607 on the report. It says "Inlet A9 gutter capture curve is not a valid curve."
A couple things I did different from the video lectures...
I selected user define for the Tc to figure out Q. i computed those manually.
For the Inlets I have selected Maximum Capture Cutoff.
There are some inlets in this model I created that do not capture 100% of the flow so i created conveyance links to account for the bypass flow.Not sure why is not recognizing the Curve?

Civil 3D 2013.
Problem with command from Home tab - Draw panel - Curves drop-down - Create Curves Between Two Lines OR Create Curve on Two Lines.
If you select the Degree option, it draws a zero length curve when you type in a valid number for degree of curve. I have tried entering it in decimal format and as ##d##'. NOTHING WORKS!

I am working on a profile of a ditch and I want to create an enlargement of a portion of the profile. What I would like to do is shrink the vertical scale of the portion of the profile I want to focus on, creating what looks like a stretched view of the profile.
This can be accomplished by creating a block and shrinking the Scale X, but is there any way to do this feature with a viewport? (Creating a block of the profile isn't the solution, especially if I need to edit it later.)
If not with a viewport, is there any other way I can do this?

I am trying to create multiple bodies within a part file using multiple ifeatures. It seems that it is not possible to force the ifeature to create a new body when it is inserted. If it is inserted into a part that has multiple bodies present.
I call it "Reverse Nesting". We have a sheet of a certain size (18" x 32" in this case). I need to completely cover a much larger (and oddly shapped) panel with these sheets. I want to cnc cut these sheets into the correct shape and be able to assemble them together on the larger panel.
Create an ifeature that creates a sheet of the correct size. In a part file with a sketch (or surface) of the panel we need to cover, we can insert the ifeature and constrain its sketch to the original sketch. My hope was that I would be able to do this multiple times (each as its own body),orient them as req'd to cover the panel, and the use the original panel sketch to do an interference extrude through all the bodies. I could then use Make Componets to create an assembly of all of the parts, and generate flat profiles for each piece for CNC cutting. This doesn't work because I can't geerate multiple bodies with multiple iFeatures in the same file.Create a template part that is teh size of the sheet and constrain them together on the panel I want to cover. Use assembly features to cut way what I do not need. This does not work because there are performance and associativity issues with assembly features and no way to push the cuts back to the parts for CNC profiles.
Similar to #2 except derive the panel we need to cover into our part and use split to remove what we do not want from our sheet. This does not work because it is not easy to move a derive around within a part and link it to the other sheets that are adjacent to it.Create a template that contains parameters that contain the sizes of the sheet. Manually create sketchs and constrain them to each other on the derived (as a surface) panel, extrude each one as a separate body and then run Make components. This will work, but it is very time consuming.

I'm trying to create an assembly and there's one part of one piece I'm struggling with. I attached a quick sketch I made of it. I'm struggling with the bend portion that I lined in. If my drawing doesn't make sense, that piece is 5" long, the bend is 5/8", and it's a cylinder. I'm sure it's really easy but I'm blanking. I've tried the bend tool to no avail.

We like to allow user to select a rectagular area in modal scpace. Then the code creates a paperscace viewport in a spcified layout. The viewport will show the selected area. find the old VBA code that achived this and the .net code I am trying with. .Net code always gives some exception.
VBA Code
'Lets find the center of the viewport in paperspace.
Dim center(0 To 2) As Double
center(0) = newWidth / 2
center(1) = newLength / 2
center(2) = 0
Dim lay As AcadLayout
For Each ent In ThisDrawing.layouts

I am working with vector art that has lines that either look like they were cut off and not finished out or extend to the edge of the page so they are straight when they should actually be curved.
Is there any way to take a straight line or part of an image and curve it with ease or will I have to redraw or alter each line?

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.

We have a large pipe project that forms a very large 'C' shape. To follow convention with advancing stations from left to right and north being up, we are running into some problems.
1). For Civil 3D, can you reverse the profile for a section, say station 9+00 to 18+00 only. The remainder would be one direction.
2). What do others use for convention for north arrow direction and advancing stations?
Our first sheet goes from east to west, the second and third sheets run north to south, the next ones are west to east, and the final ones are north to south.
3). What will be the layout/formatting?

I would like the grading of a site to happen only on part of the site; I need the rest of the site to remain unchanged.
I thought I was finished with this project, the volumes seemed about correct, and then I noticed in the comparison surface (showing areas of Cut and areas of Fill) that soil is being taken from parts of the site that need to remain undisturbed. This is a residential site with a conservation easement and other forested areas that we won't be disturbing.
How do I set a boundary or breakline (or what?) to limit the grading/cut/fill to the area I want?
