AutoCad :: How To Create Curve Using Spline On Screen
Mar 27, 2012
When I create a curve using spline on the screen I have noticed that often the curve between the points of the spline will become as straight lines. When I click on a point the curve appears again as normal and as I wanted. Any way to stop it from happening? Is this simply a characteristic of AutoCAD or something I am doing wrong? Does the curve appear as desired when plotted? The curves I am referring to are sections of a ships hull.
What changed between acad lt 2007 and acad lt 2012. Cannot draw a simple 2 point spline curve in 2012. how I do it? Is it a sys variable changed somewhere?
Spline curve command has changed. This is terrible as I used to use simple line types to show different things on my drawings that was rapid fast with custom macros etc. Now the spline curve command does not work in same way costing me hours of time wasted. I have now resorted in saving all incoming drawings to older version and completing my drawings that way. Only problem is the new drawings are growing above the capabilities of my old machine.
How can I initiate the old std 2 point spline curve in the new software so it works the same way as old version?
How to pattern a feature along a spline curve so that the resultants are separated by an equal linear distance (chord length), rather than as a function of the spline curve's length?
I have a group of Points coming from a step.file. So I don't have their coordinates, excel list or anything else. Just the step file. Around 100 points. There is a line between each 2 consecutive points.
Is there any way to select all the points and create a complete spline? Or even to select all the points and create tangent arcs between all of them?
I'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline. 2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm. 3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

Basically I have 3dpolylines and some Splines. I would like to create a road file that uses the geometry of these objects to create a single line/crest of road file.
API enhancement/fix in SP1: Cannot create a radius dimension on circular drawing curves projected from spline edges.Does it in some way trying to refer to the issue with nonplanar arcs turning into splines in drawings saved-as AutoCAD .DWG?
I have a 2D elevation drawing of a new building I am designing. It has a curved canopy that I want to put the name of the facility on. How do I create the illusion that it is on the curve?
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 trying to LOFT multiple ellipse shapes along a spline path to create a door handle. But as soon as I choose 1 section, MAX creates the shape. I cannot figure out how to create the shape with multiple cross sections. I have attached a screen shot and a pic of the door handle I want to create.
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 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 need to create text along a curve. Is there a plugin for that? I will have a graphic in a circular shape and need text at the top and bottom to be curved to follow the circular graphic.
I just got a bunch of new brushes and one of them is a series of 4 stitches that are oriented horizontally and look just like this - - - - . How can i run this in curves so that it still looks like stitches? When I stroke a path it creates a black mess(while using brush). When I drag and draw freehand the results are not much better. Is there anyway to make it so this can follow some sort of curved path? As if you are rolling the brush along a line like a paint roller and keeping the integrity of the brush? I'm using Gimp 2.6.10.

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?
I try to create a curve with 3 or more equal segments. When I draw random curve using the "Freehand tool" I always get curve with several not equal segments.So how can I create a curve using VBA Macro so that the curve has equal length of the segments.I attach two pictures with curve that i have and with curve that I need to have.
