AutoCAD Inventor :: Polar Equation Input
Sep 24, 2012I need to put in the polar equation r=e^theta. Is this even possible in autodesk? How can I do it? Should I spline through points instead?

AutoCAD Inventor :: Input 3D Cartesian Coordinates / Batch Input (x / Y / Z)
Feb 4, 2013My need is to create up to 50 points from the same origin in a three dimensional Cartesian coordinate system but I’d also like to have a labels for each point that show up in the feature tree.
Are there Inventor 2013 plugin (i.e., add-on, 3rd party, AP) to convert a list 3D Cartesian coordinate system locations (i.e., points) to Inventor to work points(x, y, z)?
I found that I cannot create 3D points in the assembly. Is this correct? I did find that an Inventor part may be used to create a 3D sketch that creates points in 3D space. In the past few days, I found two ways to create 3D points within a iPRT; the batch way uses an Excel file but it then does not allow me to name the points in the feature tree. The second way is to create them one at a time but that take way too much time.

AutoCAD Inventor :: How To Make Surface From Equation
Nov 26, 2013I need to make a model of saddle surface. The surface is given by equation z = y^2 - x^2, and I must have some thickness - It will be printed on 3D printer.
I have Inventor 2014 and I dont see possibility of making the surface directly in Inventor. Is there any trick for that?
I'm afraid I cannot use solution as stated here Equation-driven surface , because saddle surface looks like this hyperbolic paraboloid .
I tried this solution: I made 3D surface in Matlab, exported it in .stl and opened in Inventor - but this only makes the surface with no thickness. Functions extrude, loft require 2D sketch.
AutoCAD Inventor :: Equation For Rectangular Pattern
Feb 22, 2012Can an equation be used to calculate equal distances when using the rectangular pattern.Regarding the attached .ipt file i would like to place 25 holes in the X direction with equal gap size between each hole.Also how to calculate the number of holes in the Y direction again with equal distance between each hole.I have not done this before with equations but was thinking that i would need to use the Length x Width in the equation.Do i need to add figures into the Parameters box also?
The attached file with the Hole feature the sketch is not constrained for the purpose of using an equation so i know how far from the start of the part to get equal distances between each hole to the end of the part .

Jan 16, 2012We have some equations in our templates which i have modified with iLogic. Once the rule is run it only shows the value and not the equation. ie i want it to show Thickness*2 instead of just '12'. The ilogic will say something like InnerRad = Thickness * 2 Is there a way to make it show the equation rather than the value? While i know whats going and can see the driven link in the parameters the planned change to 2012 could take some getting used to for users.

Is there a way to do this with drawing dimensions? ie dimensions created in drawing mode?
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.

Oct 14, 2011I have a small assembly with the parts. I'm doing an array (pattern) of one of the parts and I tried to do two things without success:
1. Tried to link one of the parts to the assembly itself with the equation tool ,but the software doesn't let me do it and says "...was rejected since it causes a cyclic dependency" - so what?:-) I know and need to do it!
2. After rejected the first choice, I tried to "project geometry" some stuff of the pattern I created in order to try and and make my connection in this way, but then I got a similar rejection: : problem encountered when doing cross part projection"...probably it's because it's from a pattern I'm creating from the part I'm doing this sketch inside?
What Can I do in order to bypass these remarks and make it somehow? Most important, Why can't one "tie" something from a part to its own assembly in which it's located???

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 Inventor :: IPart Factory Table On Drawing Show Equation Not Value For Parameters
Oct 21, 2008I have an iPart that I have created parameters to perform some basic calcs so the values will show up on every member. The parameters are correct for the different member so it appears to be working correctly on the model side. For example I have a parameter called 'CutLength' that performs simple math functions. But when I make the table on the drawing and I include this parameter, I see the formula in the table instead of the value. Is there a way I can have it display the value instead of the equation?
