The path array in 2012 is a very useful addition but I can't crack a solution to creating an array around an elipse (like chairs around a board room table). The only way I've found it to work is to break the elipse and then join up the gap, essentially creating a closed eliptical arc. This gets a result but it seems a very scrappy work-around to something which should simply work.
View 3 RepliesI would like to arrange equally spaced circles around an ellipse. I understand I can do this with the Divide command, as referenced in a previous thread on a similar subject
[URL].......
But I thought I could also use the Path Array command using an ellipse as the path.
What I get is the replicated objects (small circles) following some totally random path. Strange that this happens only with an ellipse - seems to work OK if the path is a circle or spline.
I need to make an ellipse that's cut in half, and I have no prior 3D experience that's useful to create this shape.
View 9 Replies View RelatedI 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.
sequence for creating a Polar Array? I have no problem with Rectangular Array but for some reason I have no success with Polar. include what it should say in the command line in the sequence.

I'm trying to create a window block with a grille. I've created the block and the horizontal grilles. What I'm having a hard time with is creating the vertical grilles. I would like to set up an array that would take the glass width, divide by 12, round up the value to get the number of vertical sections. Here's the code that I've figured out:
(W/(ceil(GW/12)))
W=Width
GW=Glass width
How do I set up an array with this formula?
We are developing a simulation of bugs living on an island. Now we need to know if the bugs are on the island or not.
We have an image of an island (see attachment) and we want to create a grid array. We want to create an array (or at least want to know) in which grid fields the color red is.
The image in the attachment is very small, in real it's much bigger. So we have a grid of 5 px size.
I have modeled a theatre chair, and when I attempt to create a circular array the left arm/leg of the chair separate and rotate 180 degrees in the opposite direction. I am able to select the entire object but when I attempt to move/ create the array...pieces split and go in different directions.

View 2 Replies View RelatedI'm trying to use the PATH array feature on 2013 to array stairs, and I can't get the array to be 100% accurate. It seems like CAD rounds the decimal to the nearest 3/4" which could be causing the problem.
I set my run to 10.5" and rise to 7.25", array along the angle of the stringer, and there's always a small overlap on the stairs. The "distance between" should be 1'-209/256" and CAD rounds it to 1'-3/4" which is where I believe the error is. Is there any way to fix this or array this correctly? Otherwise...back to the COPY method I suppose.
I am trying to create a cylinder. To accomplish this I am creating two ellipses and two lines. After I try to insert them in the DWG dwaing I can see only the lines. Here is a code sniped so you can see what am i doing.

I'm trying to make a (for lack of a better term) squarish ellipse.
I've tried a few things but they don't work too well, i.e. plines and lofting a rectangle with an ellipse then cutting it two but they just get me arcs that meet at sharp points.
The jpg below is meant to show what I'm trying to do.
I want to take that one quarter of an ellipse at the intersection and stretch/pull it to the midpoint of the line between the corner of the rectangle and the arc. The ellipse is made out of 4 ellipse arcs. I want to stretch just the arc without moving the ends of it at the quadrants.

View 3 Replies View RelatedI 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.
Recieved a ACAD converted Microstation File for use in an upcoming construction project. Would like to convert all of the existing ellipses to polylines. Have read several threads that lead me to believe redrawing them is about the only real way to do it. Posting here in hopes of a solution. Drawing contains 127 ellipses, and I dont want to redraw all of them!!
Currently on C3D2012.
I want to create a new order. when using the order,It will create a ellipse and a DTEXT .I mean the ellipse and the DTEXT are a whole. when move the ellipse the DTEXT will alse move.However, users can edit the DTEXT.

I have a database of the 50 stars closest to the Sun. I wrote a program that translates Right Ascension and Declination into X,Y,Z coordinates on the "normal" UCS view.
I created all stars in 3D, distances to scale (1m = 1Ly), stars as spheres 0.1Ly radius (so they are visible !) Now, I need to draw the elliptic trajectory of a rogue "planet", starting near Lacaille8760 (6.456, 7.664, -8.076), passing near the EZAquarii, A, B & C, located at 3.557, 10.268, -2.973, to get a slingshot that will launch the planetoids towards the Sun (0,0,0). The elliptic trajectory should be a 3d "tube" a few pixels dia.
Problem:
How to set the screen coordinates to the plane formed by the 3 points above, so the ellipse can be drawn on a plane ? I changed the UCS to 3 points, and the screen shows the three stars on the same plane, but when drawing the ellipse, it is to the original UCS...
I'll make the ACAD files available for download at [URL]...... "TECH" tab. Once created, the drawing is used in R14 format to be imported in 3DSMax8 to get easier views and animation.
I'm having difficulty with a sheet metal part creating a flat pattern for it. The shape is an ellipse with the dimensions shown in the second picture. 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?

I know that stretch will not affect major or minor radius of an ellipse in dynamic block.
What I would like to be able to do is use properties of an ellipse and some kind of parameter to be able to affect values in properties.
I know how to get ellipse radii data out of a block, but I simply cannot find a way to get them back in...
Is there a way to link field data back to block...?
Is there a way, using dynamic blocks, to rotate a line around an ellipse, so that that leader is always centered with the center of the ellipse, but it actually starts at the circumfrence of the ellipse.
Like with a circle, you choose, rotation, using the center of the circle as the base point, and then setting your radius, and choosing the 'rotate' action. I need to do basically the same thing, but with an ellipse.
I'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...
