AutoCAD Inventor :: Super Ellipse Equation Curve
Dec 11, 2012I'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 RelatedAutoCAD Inventor :: Why Does Equation Curve Function Not Work
May 10, 2012Trying 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.

AutoCAD Inventor :: 2D Equation Curve For A Parabolic Spiral
Jun 22, 2013what 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:

AutoCAD Inventor :: 3D Sketch Equation Curve - Creating Coil?
Jul 26, 2013I 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
AutoCAD Inventor :: Variable Pitch Helix By Equation Curve
Jun 20, 2012You 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.
AutoCAD Inventor :: Equation Driven Curve - Unit Error
Nov 27, 2013I 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.

AutoCAD Civil 3D :: Forcing Vertical Curve Low Or High Points To Specific And Precise Station?

I can do it with grips, but it's imprecise. In the project I am currently working on, I have some leeway regarding the slopes into and out of the vertical curve, so I have some flexibility, but some of the LPs and HPs need to precise.

AutoCAD Visual LISP / AutoLISP :: Change A Specific Attribute From Specific Block To Specific Value
Dec 7, 2011I've had a simple lisp I've been using for years that suddenly disappeared. It required that you identify a block name, tag name, and the value that you want the tag to be. All of this is performed via command line, so it is scriptable. Since I lost it, I've been experimenting with -attedit. This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.
1> Any lisp routine that does what I describe?
or
2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?

Does the curve appear as desired when plotted? The curves I am referring to are sections of a ships hull.

AutoCAD Visual LISP / AutoLISP :: Create Polygon Viewport At Specific Scale
Apr 25, 2013I'd like to run one command that allows the user to draw a polygon viewport then sets that VP to 1/8"=1'-0".
It can be nearly accomplished with a macro, but falls just short because the polygon vp requires an unknown number of clicks, so there is no way to know how many pauses for user input in the macro.
