Hi Zoo inmates,
I’m wanting to create a very shallow dish on one surface of a rectangular block. Let’s say 100x150mm and 15mm thick. One of those 100x150mm faces should have the edges and corners say 0.1mm higher than the “center” (center being a bit hard to define because it should be a flat central area, say about 33x50mm). The way I’m imagining it is that I take a soft ellipsoid balloon (shaped like, say, a rugby ball) and press it against the surface. I’d then use the shape that the ellipsoid balloon would take when pressed against the hard surface, and use Boolean Difference to subtract very slightly from the surface of the block, leaving a shallow dish.
I just tried using a wide, shallow ellipsoid and it might do the trick, but if anyone can suggest a way to deform it like I described above and then use I feel like it would give a better result.
You can edit the control points of a surface to get a similar effect. You might have to rebuild the surface so you have a control point in the center or with 3 x 3 divisions even 4 points…
Okay, I’ll give that a try thanks Martin. I’m very bad with surfaces - hardly ever use the surface-related functions - so it’ll be a good chance to get some practice.
Command: _Plane
First corner of plane ( 3Point Vertical Center AroundCurve Deformable ): Deformable
First corner of plane ( 3Point Vertical Center AroundCurve UDegree=3 VDegree=3 UPointCount=10 VPointCount=10 ): UPointCount
UPointCount <10>: 3
Number must be bigger than or equal to 4
UPointCount <10>: 4
First corner of plane ( 3Point Vertical Center AroundCurve UDegree=3 VDegree=3 UPointCount=4 VPointCount=10 ): i
VPointCount <10>: 4
First corner of plane ( 3Point Vertical Center AroundCurve UDegree=3 VDegree=3 UPointCount=4 VPointCount=4 )
Other corner or length ( 3Point )
1 open surface added to selection.
Sorry to dump this just like that but you see what I did here… It’s a simple surface with 4 control points in U and V direction and then F10 to show the control points and move them down a bit with the gumball.
Wow, thanks Martin. I’m going to need to play with this and read the help files as I go to try and make it stick. Many thanks - you’ve also taught me something there about F10
