Okay so is there anyway to enter the whole equation of an ellipse into autocad and it will map it? ex x^2/a^2+y^2/b^2+z^2/c^2=1 with different values for x y z a b c. I want to generate different ellipses and then loft them together?I just want one the starts with the basics and goes all the way to the move advance stuff.
View 3 RepliesI'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?

I have an ellipse with equal radii, I changed it into an arc, but I can't make it fit.
In the attached drawing, there are 3 entities.
1. The original ellipse - red
2. Arc that has the same start angle and end angle as the ellipse - grey
3. Arc that fits the original ellipse - green
Now this is strange, because the ellipse seems to have a different CS for the angles. I had more ellipses in the drawing, but some of them don't have this anomaly.
I've always used the spacebar as Enter, it speeds up the way i work.I've just load 2013 and i'm using the Drafting & Annotation workspace, now when i use the spacebar it jumps to another command, i have to use the enter key to get it to do what i want.For example.
Type H, (spacebar), S, (Spacebar).
This should be - Hatch > Select,
instead i get 'Hatch' then it cancels the hatch commands and jumps to 'Stretch'
Our customer send us drawing with ellipse into.With Autocad 2008 I bought a plug-in call SplineConvert that did the job perfectly but not compatible with 2013.
Is there any plugin that could replace that tool ?
Is there any standard ACAD command that could easily do this Job ?
I need a way to make 2 or 3 times per week this converting on all ellipses of large and detail 2D drawings so no time to offset in and out all those .
I try also DXFOUT in R12 but all the spline are being converted into 3d polyline making a huge files that froze my PC.
I also try FLATTEN but did not see how it work , the ellipse stay an ellipse.

how math works for scale factoring to specfiy a smaller or larger inserted object. Working with a door. I want to set the door at 3'. To do so I need an X scale factor for 12.
The factors for factional inch scale is derived by multpying the denominator of the scale by 12. Then dividing by the numerator.
Example. If the scale for 1/4" = 1',0" is ( 4x 12) / 1 or 48/1.
Not sure if these figures below have anything to do with the scale Factoring problem at hand. But.
For 3/16" = 1'-0" scale the operation is (16 x 12) / =3, or 64.
For whole foot scales like 1" = 10', mutlpe the feet side of th equation by 12.

I 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.
Can 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 .

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.

The spline is of degree 3 and is fixed at points x1, y1 and x4, y4.

Is there anyway of calculating the equation that represents the spline?
I was trying to use ipart to create some parts and place the relevant dimensions in the table format in the idw file.

Trying 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.

View 1 Replies View RelatedI 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???
