Milling a sphere

Dec 22, 2021

Apr 18, 2007 cutting a sphere I am trying to make a cut through a sphere. I have a profile, but when i try to cut the profile from the sphere, I only get the option to extrude. Can anyone tell me what i'm doing wrong? If you need an example, imagine an icecreem scoop. that is what my part looks like, but i need to trim off some of the sides of the scoop

    The word hemisphere can be split into hemi and sphere, where hemi means half and sphere is the 3D geometric shape in math. Hence, a hemisphere is a 3D geometric shape that is half of a sphere with one side flat and the other side as a circular bowl. It is formed when a sphere is cut at the exact center along its diameter leaving behind two equal hemispheres

With a UV sphere, I size it to my requirements, set scale to 1.0, select editing mode, press Numpad 5, press Numpad 1 to get to Front Orthographic view, position the cursor above the center top, drag to select half, press DEL, and select Vertices

  • Sphere Volume Calculator

    Dec 02, 2020 A sphere is a perfectly round geometrical 3D object. The formula for its volume equals: volume = (4/3) * π * r . Usually, you don't know the radius - but you can measure the circumference of the sphere instead, e.g., using the string or rope. The sphere circumference is the one-dimensional distance around the sphere at its widest point

    Fixing a sphere to a point in dependent sketch. I have a sphere placed on the centerpoint of a circle (d2). The circle (d2) is dependent on the diameter of another circle (d1). When I change the value of d1, d2 changes but the sphere does not stay fixed on the centerpoint of d2. I suspect it has something to do with timelines

If you had a hollow sphere, and are allowed to cut it with a 2D knife (i.e a plane) 5 times, what is the maximum parts you can get and how? I figured that the upper limit is 2^5 if you are allowed to arrange pieces after each cut. In this problem, this is not allowed

First of all you need a top quarter or third of a sphere : well, if you scale a sphere shape (btMultiSphereShape with only one point and radius plus local vertical scaling) you can get a surface like the one you're looking for (except that it's mirrored vertically)
