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.
View 1 RepliesI want to draw hyperbola curve whose equation is x^2/a^2 - y^2/b^2=1. May I use equation curve tool to make the above hyperbola.
I have also made a hyperbola curve of aforesaid equation through conventional method on mathematical ground in the past.

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...
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?
View 1 Replies View RelatedTrying to do something as simple as y=x^3 (Explicit Mode). Set xmin = 10, xmax = 20 then tried y(x) = :
1in *(x^3) -- no good
(x^3)/1 in -- no good
(x/1 in)^3 -- no good
Error is that "Equation y(x) contains errors. Expected units are length".
The point here is: Why should typing in such a simple equation as y=x^3 be so difficult??? Can't even do (x*x*x)/1 in & make it work.

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 have also found this: $r^{2}=a^{2} heta $
Please see image attached.
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
tmin: 0 ul
tmax: 0.916 ul
You can create a variable pitch helix by using the Equation Curve feature introduced in Inventor 2013.
Create a new 3D Sketch. Start the Equation Curve command.
Here are equations that I use to create helical curves. Many other variations exist.
Cartesian coordinates:
x(t) = radius * sin(360 * num_turns * t)
y(t) = radius * cos(360 * num_turns * t)
z(t) = height * t
[Code]....
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:
"y=sqr(2)*16.5/2/sqr(pi)*sqr(arccos(1-2*x/50)-(sin(2*arccos(1-2*x/50))/2))"
I modified it, inserting variables which I defined also in inventor, leading to this:
"sqrt(2)*height/2/sqrt(PI)*sqrt(acos(1-2*t/length)-sin(2*acos(1-2*t/length))/2))"
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.

View 7 Replies View RelatedI used polyline to trace a tree trunk. I wanted it to be just a series of line segments which I was going to export to AutoCAD and then to Sketchup. However, each segment I drew said it was a curve. When I exported to AutoCAD it came in as a spline. If I convert that to lines, where I had maybe 10 lines there are now 100.
I also tried to 2 point line tool. I started each new line from the end of the previous. It gave me the same result.
Is there a way for me to end up with just the 10 line segments? No spline. No curve. Just 10 straight lines.

View 10 Replies View RelatedI'm try to automate the importing of the Varaible and datasets into my graphs via Scripting, but the ImportVaraibles() function doesn't seem to work. Here is my Script, mostly copied from the example script provided with Illustrator (CS5). And, this works manually, using the file names in the script, via Load Variable Library
Set appRef = CreateObject(strIllistratorVersion)
'Open the file and import the datasets
Set docRef = appRef.Open(strTemplate & "200-500.ai")
'docRef.Datasets.RemoveAll
docRef.Variables("Yearbook").Delete
Here is the problem, after I delete the previous library, then this next line, right from the example, does nothing
The script then exits with 'No Datasets in this document'
docRef.ImportVariables (strXMLFolder & "Lumber_200-500.xml")
'appRef.DoJavaScript "alert('Template:" & strTemplate & strRange & ".ai | XML file:" & strXMLFolder & "" & objFile.Name & "^')"
If (appRef.Documents.Count > 0) Then
Set docRef = appRef.Documents(1)
[Code]....
If I remove that delete line, the script runs, but just uses whatever Variables I had last loaded, not the XML file.
It's simply not loading. What do I need to do to get it to load?
