AutoCAD Inventor :: Evenly Space Points On An Ellipse
Jul 26, 2013I need to evenly space points along a drawing of an ellipse, and I can not seem to figure out how to do this.

View 4 RepliesI have an ellipse (blue shape in screen shot) 120mm tall / 135mm wide;
and then I have ELEVENT tabs (magenta in screen shot) that will be attached to this; these tabs need to step and repeat evenly around the ellipse.
how I could achieve this effect?
Any way to evenly space contours around a curve in a surface.
Many times I have a steep area in a surface that needs to be displayed using 1 foot contour intervals, and in certain areas the contours are crossing each other around curved areas, like a curve in a ditch. In the past i have had to "fudge" the surface a little to get the contours to look correct.
I would like to write some sort of AutoLISP program to evenly space objects across a given distance. I have attached a .pdf file showing what exactly I mean.
I would like the program to enable me to either enter or measure (via the selection of two points) the "z" distance, to enter or measure the "y" distance, and to enter the number of objects, "n". I would then like the program to evenly space "n" objects across the "z" distance.
A program like this is, I have to be honest and say, way beyond my current capabilities.
Perhaps some initial guidance to get me going?
Is there any Command / Lisp / Parametric way of obtaining a "prospective" ellipse from a set of 5 points?

I have 4 lines of text. They are currently in 4 separate layers as they are 4 separate buttons. How do I make sure the verticle space between them is even?

View 7 Replies View RelatedI'm working in Adobe Illustrator CS6 and neither the Distribute Spaces Option nor Distribute Object Option are working.It doesn't seem to matter if it's a print or web document. Doing the same thing to the same document/graphics in CS5.1 works perfectly.
Copypasteing the correctly distributed objects from CS5.1 to CS6 works ok, and if i then repeat the Distribute spaces option nothing changes and it stays correctly distributed. (read: it doesn't badly distribute like before)
I want to draw up a large grid or table in AO sized paper. I will then get it laminated and use it to write down on the left hand column each company I see and sell to. Then beside the company running horizontally I want little check boxes that I can tick off with a marker to not when I last visited that company.
So how doe I make a large sized table with evenly spaced columns and rows etc.
I though that I could just select the table button and set how many rows etc then click and drag. This works, but I want to be able to enter in a value of say 100mm wide by 30mm high and set that for each grid.
The only setting like that is for the actual whole area of the grid/table not each individual cell. Can it be done like how I said?
I have a radius that is spread between 10 and 40 degrees that I need to evenly space 6 line segments throughout.
What this is for is a property with 5 lots along a curved street. Each lot is the same size and I am trying to draw just the sections that are affected. I have tried using the star feature and reducing it to single lines, but they do not space evenly and getting the line number is very difficult. I have tried dividing the angle range and come up with the correct angle and spacing but this is also an issue. Is there any way to do this without dragging each line separately?
In the above image, I have four symmetrical corners of an ellipse which I'm trying to join together into one ellipse that is perfectly symmetrical. I am trying to line up the anchors perfectly (one corner at time) and then do a join, yet the result is always slightly off. I've been selecting the two points I want to join and using Path -> Average, then Path -> Join to do this, yet as mentioned it's not coming out precise.

When I attempt to create a flat pattern it just shows the side of the part. The sheet metal defaults are correct for the part and it was ripped to created a base point for the pattern. I need to create a DXF for manufacture. I would just use the flat pattern it gives me and mirror it twice to create a pattern but it doesn't factor in the radius of the part. How to create a correct flat pattern for this item?
View 5 Replies View RelatedI'm trying to dimension an ellipse in the Inventor Drawing Feature. I've attached the .idw files. (the .ipt is too large)I am aware that the ellipse doesn't have a constant radius and was wondering what is accepted practice for these dimensions?
I need to first dimension the external elliptical shape (which I'm struggling at), might just add a note.
Secondly I'm trying to dimension the mesh part, its not centrally align to the part and since I can't put a center mark on I'm not sure how I should dimension this...
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 4 Replies View RelatedI have build a solid in which the projection of the hole on the face of the cube is an ellipse. However, as I did not create the ellipses on the faces, but the ellipses are just the result of the projection of an empty egg inside an extruded rectangle on the faces of the extruded rectangle. How can I see the dimensions of the ellipses? I tried to use the measure distance command, but with no success.
I´m attaching the model file.
I want to make a sweep around an ellipse shaped path. Somehow when Inventor is asking for the path it does not want to select the ellipse.
When I try in 2011 it does. Try in 2012 with attachment, no luck
I am having trouble creating an extrude-cut from an offset ellipse. It seems that when the ellipse is offset, it becomes an associative spline. I need it to remain associative with the original ellipse.
But, when I try to extrude a profile using the new spline, it won't recognize the edge.
I can't just create a new ellipse, as it's profile won't quite match the offset one. I tried tracing over the ellipse with a spline, but it then requires a vast amount of dimensions to constrain it all together.
I'm trying to extrude-cut the red outlined profile (including the elliptical part of course)..
Here is the part. I am working in Inventor 2009.
I am currently working with an elliptic profile that needs to be unfolded. The part consists of two sketches, with each sketch having two ellipses. The ellipses on each sketch then forms a cross-section where the thickness of it is supposed to be 8 mm (the first ellipse is offsett).
My plan is then to generate a mold for the inner and outer sides of this part by using the "Lofted flange" function and Rip, since I want the flat pattern of it. However, I've found that I can not select my offset ellipse when using Lofted flange, only the original one. I'm thinking that this might be caused due to the offset ellipse not actually being an ellipse but a spline (I read somewhere that there are two ways of offsetting an ellipse. One generates a mathematical ellipse and the other a spline). Creating an new ellipse and then saying that the a and b distance should be 8 mm less than the other ellipse will work, but that will not give me a constant wall thickness of 8 mm along the circumference of the elliptic cross-section.
create an ellipsoid with a hyperbolic funnel on the end.
How can I join an equation curve to an ellipse to create revolved ellipsoid shape? I also have alias and fusion if these are needed.
Why can't Inventor constrain an ellipsoidal contour with a line? We have pressure cylinders which uses a 2:1 ellipse. These cylinder get welded to a base stand fixture. The surface of the ellipse nestles in between contact points of the base stand, in this case lines of geometry. Yet Inventor can't constrain them as such. Any good workflow (at the assembly level) so that we don't have to ground components and use the Analyze Interference tool to make sure we are right on the surfaces? I don't understand why it will work for a cylindrical surface but not an elliptical surface.

View 3 Replies View RelatedI am trying to export geometry found in a flat pattern sketch overlaid onto the flat pattern.
Since I am creating the output file manually I gather the flat pattern boundaries and bend center lines for output to a file.
When I add flat pattern sketch entities to the mix they do not overlay properly. What matrix would I have to push the sketch entities through to get them to the same coordinates as the flat pattern?
