I've been looking around and couldn't find a solution. I have a sphere which I'm able to project on a sketch of smaller circles which I'd like to engrave over it's surface, yet I want each of them to be perpendicular to the surface of the sphere in each point. Emboss doesn't do the trick, it just makes the engraving perpendicular to the plane.
Can someone please help?
Solved! Go to Solution.
Can you attach the file here?
You might want to Split and Thicken or some other technique.
I currently have no access to the file, but the sketch below is a basic concept of how the other side of the shell should look like. It's basically a dome with lots of pipes penetrating perpendicular to the surface at each point of entry.
I'm not sure I follow your trail of thought regarding use of the Split command.
Thing is, if there was a way to apply the Extrude on a 3D sketch that would've solved it all, as the circles in the 3D sketch are projected on the phere and thus perpendicular to its surface, but all I get is "No visible adapative sketches".
I currently have no access to the file, ..., as the circles in the 3D sketch are projected on the phere and thus perpendicular to its surface,
I will wait for the file. Circles are 2D (planar) by definition.
Sounds to me like you need to convert them to 2D sketches and Extrude.
First, thanks for your help!
Here's the file, the inner shell sketch (3D) should be holes, and the outer shell sketch should be pipes, both should be perpendicular to the surface of the cap. It's driving me nuts as I'm sure there's a way to do it.
Projecting a 3D sketch onto sphere as you have does not result in circles.
Imagine you were drilling those holes on a drill press.
How would the centerline axis for drilling be set up?
You have two rows of holes in Projection 9.
Will those holes be drilled with parallel axis or will axis point to common center?
You're right, I haven't noticed that but around the edges they do stretch.
The centerline (if I understood you correctly) would run from the edges to a common center, (two centerlines, one for each row). I thought about creating a plane perpendicular to the point on which I want to create the circle, but this means a lot of planes...
Hope I understood you correctly
Most likely can be created with a Circular Feature Pattern depending on your true design intent.
I've used the circular pattern to make the holes that are on both sides, and then I've deleted some so maybe I'll put them back, not sure yet. Still, I can't define them as holes, and I can't create the big circle (inside of the cap) as an engraving.
Nor does it solve the two rows outside where the pipes pentrate the cap as well. How can I define the holes for the pipe as perpendicular to the surface?
I'm sorry but I'm still not sure how using a circular pattern helps...
Disregarding several holes which can be cancelled due to their distortion in projection, the question of how to create a hole on a surface of the sphere remains (without creating a work plane of course). Also true regarding the embossing of the big inner circle.
I'll appreciate any help.
