I'm trying to use the equation curve to draw a super ellipse.The formula I'm trying to translate for inventor is the following.I'm guessing this should be possible using the abs() for the first section and an IF() statement for the second. The problem is Iäm not even getting the abs() to work at all. How to translate this formula?
what the 2D or 3D equation curve for a parabolic spiral, otherwise known as a Fermat's spiral would be? I have found this info but do not know how to apply it:
Fermat equation
Therefore in terms of the affine plane its equation is The Fermat curve is non-singular and has genus
I am trying to create a coil which from above, retains equal and thus parallel pitches whilst at the same time adheres to a semi-circular form in the cross section. You can see from the images attached that the first two revolutions are larger than the semi-circle outline.
These are the values I have used:
Cylindrical
r (t): 134.56924424045517662353735770102mm * t * 0.5 q(t): 1 deg * 360 ul * 3.0 ul * t z(t): 10 mm * 6 ul * 0.5 ul * t * (1.5 * t) * t
When you sweep a profile along a helical path, use the plane normal sweep (instead of perpendicular sweep) to orient profiles suitable for coil or spring. In the example below, the sweep path is a constant radius, variable pitch helix.
I would like to create an equation driven curve with inventor. I have no problems plotting the function in a plotter, however, inventor won't accept my equation. It gives me the error message, saying: "The equation contains unit errors". I'm using the explicit equations.That's the bare equation:
But both equations are not accepted by inventor due to unit errors. In this design, I'm using the metric system, millimeters, so I don't understand why and how I have to redefine this for the equation in order to get it working.
Is there a way to graph a curve using an equation over a closed interval in Inventor 2012? I know I can draw a spline through points that are solutions of my equation, but this does not guarantee that the curve is the graph of my equation.
I am trying to write a script to draw geometric figures in Illustrator.I want to achieve this by writing an equation into the ESTK, for example x^2 + y^2 =100. This should generate a circle with a radius of 10 units.
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?
Why in LR4 is the Tone Curve default set to Custom with a contrast lowering curve? I would like the default to be linear, but I can't remember how I set that up in LR3.
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 occasionally have the ACE become inaccessible at the bottom of the GUI. Can still get it on "F5" but no editorial buttons. How to get it back without restarting.
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.
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.
Any unpublished system or drawing variable that allows you to toggle to the classic grips on a curve-fit polyline? I have searched online and checked with our reseller but we have been unable to find a way to switch to the historic grips that are available on a curve-fit polyline.
Is it possible to create a block that conforms to a curve in AutoCAD 2013?
In this case I want to have 3 lines that will intersect an existing line at 1 meter intervals - which is simple for straight lines, but when the existing line is curved my current block setup just isn't cutting the mustard.
The only thing I'm trying to achieve is to have a block that will place these lines at 1metre gaps (with the distance measured along the line I'm placing it on, and not the shortest distance).
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.
