AutoCad 3D :: Extend A Cone / Pyramid-like Object?
Sep 29, 2013
Assume that I have an odd pyramid 3D-solid say with a polygon basis that lies on a "floor". The apex was higher than the ceiling, so I "sliced" the pyramid to fit it right under the ceiling.
Now, I change my mind and want to make the ceiling slightly higher (say, 1"): after raising the ceiling I am left with a sliced pyramid that is cut 1"below the ceiling. Question is : what is the best way to re-extend the pyramid (and make it look like it was cut by the higher ceiling) ?
I cannot just "undo" because too many things happened in the meantime.
I can imagine re-creating the unsliced pyramid by press-pulling the upper sliced surface and then slice this extension with each side of the original sliced pyramid and ultimately re-slice with the new ceiling. Can I do better / faster than that ?
how to extend a solid object. You can see at the picture that I attached what I mean and also I will try to explain. I draw a fence 1.5 m high. At one specific part of the yard I want the fence to be 2.0 m high. So I moved upper part (horisontal) of the fence to the height of 2.0 m. Now I want the 2 vertical poles to "extend" to that height. Now I can delete those poles and use extend command from the bottom and then use silce command. I was just wondering if their is a command that I can use to grab the pole as it is now and pull it up to the new height if that is possible without erasing it.
Just picked up this Extendscript for a quick utility function. I can't seem to use any of the "usual" Javascript logic contstructs to test for undefined object properties.
Example:
typeof(app.activeDocument) === "undefined"
This is an *error* in Extendscript (Error 1302: No such element). I don't believe it should be, but if I'm supposed to do something different in Extendscript.
I am creating three shapes out of a pyramid. I figure if I split the pyramid in half, I can create two, then mirror them and blend the two together to make the final design. I have figured out how to create a pyramid by extruding a cube with a taper.
My pyramid is 40mm x 40mm x 40mm. I need to cut it in half, diagonally, top to bottom.
When I have the pyramid in the workspace, I see nothing that I can select - that will allow me to create lines where I need to - to cut them out.
I'll add a logo in 3-d that I am trying to create. (also, I am using this project to familiarize myself with the software.)
I want to create a pyramid with a base of three sides with different lenght. In the end i want to have a solid where i can drag and move the notes to change the hight,lenght and the angle of the sides.
I already managed to draw it in 3d but now i want to convert the drawing into a solid and keep it flexible to change the parameters by draging the notes.
I also tried to extrude a triangle with a specific angle but then i was only able to move the top note up and down changes the hight. Doing it this way the top note also kept beeping in the center-point of the triangle.
I am trying to produce a sketch in 3D of a truncated pyramid, base 11 meters square and top 20 meters square. Its 80 meters high and I need to twist the top 45 degrees to create an iconic tower for a friend in Brazil.
Have drawn the pyramid but how can I twist the top and make the vertical lines follow?
I have been trying to create a 3D pyramid using Illustrator CC. All the tutorials I have found have been telling me I need to create a custom bevel, but the Bevels.ai file is not in the plugins folder as it used to be. How do I create a custom bevel in Illustrator CC?
Is there a way in Inventor (or any other Autodesk Design Suite program) to find the point on a cone (attached jpg) where the lifting lug should go so that when lifted, the cone stays in the same orientation as in the attached picture.
I am trying to place some objects on a cone. But i can't get it to work. The idea is that the 6 objects should be fitted on the cone so that they are placed all around the cone. But i can't get them to align with the angle of the cone. I have tried the 3D align, but this just doesn't work for me.
I have a cone shaped part and would like to put a hole in the curved face. I would like have to hole square to the face in the flat pattern so it can be cut on the plasma table, is there a way to do this? I attached the part with holes in the approximate location.
I'm following a "Simple Mass Creation" exercise in a Revit book, which says to create a cube, a sphere, and a pyramid. It doesn't say how, though, it just goes on to the next step of dividing the masses into floors. After much research and trial and error, I figured out the cube and sphere, but how the heck do you create a pyramid? At first I was thinking of a blend, from a square to a point, but that's not an option. Then I tried to use void shapes to remove parts of a cube...and I'm getting an error message because my voids are overlapping and there's no solid to cut. There MUST be a faster and less complicated way to create such a basic form.
We're seeing strange behavior on all of our workstations when using a Refold feature on a sheet metal cone. Surfaces are (very incorrectly) being added at the top and bottom openings of the cone when the Refold feature is added. The behaviour is the same whether using Contour Roll or Revolve. The surfaces dissappear when the cone is revolved to a lesser degree, such as 200 degrees instead of 359. The cone can be revolved to 360 degrees and ripped but that raises a whole nother problem because Inventor does not correctly refold a 360 ripped cone. File attached. By the way, the surface artifacts show up in the flat pattern as well.
I have started a project and have a somewhat unusual condition. I have a structure with a Conical Roof. We are putting a parapet around this roof. With the parapet, we are also going to create 4 individual structures that direct water/rain flow to scuppers that will be fabricated into the parapet. Below is a sketch of our condition. How to get the shape of a line that follows the face of a cone. Obviously, this line is not projected to the center of the cone, so it is not just a straight line. I am imagining either a radial cut piece, or a complex/multiple radial cut piece. I don't really know how to put it into words exactly.... Take a look at the sketch.
Is there a way to correct the slight inverted pyramid effect caused by a 17-40 when taking interior room shots in Lightroom or do I have to go to PhotoShop to do this? I have found the lens profile correction but are there other tools in LR to use? What I am seeing is a slight outward shift from floor to ceiling on side walls and need to straighten these walls.
How to draw with sheet metal rules centric cone? Ive spent hours on it and nothing, it always end up on ASM failure, or ceates the only one half( when sliced on asymetric way). This need to go in two halfs.
Ive tried:
two circles 1300 and 300, top circle centre moved from Y by 127mm on X axis.
contour roll will revolve on axis between circle centre points, than extrude something with cut and it is but the shape is an oval not circle.
Ive used loft command and slice command but only one side picke will work with flat pattern.
I am currently in the process of doing some traffic management drawings and need some road signs, but mainly im after some free cone software apparently. You can get some really good software, free if possible if not then the cheapest available. This is for autocad 2008.
