"Exactly Jesus.  That was the logic I was following - just having some problems with component selection.  Thx."

"Isn't there an example about this? You only have to set the radius or the height of the cylinder as a function of it's area and its height or radios. "

### Optimization of a Right Circular Cylinder

To All:I have been trying to work through some of the examples of Galapagos with some modest success, but I have really been wrestling with one problem in particular.Let's say I have a right circular cylinder of a predetermined surface area, say 600 square units.  I would like to optimize the volume of that cylinder using Galapagos.  I have tried a couple of different approaches but failed.  I am open to ideas/thoughts from the group for solving a problem like this in Galapagos.NeilSee More

### vector intersect with plane

Hi all:I am just working on a small grasshopper problem of trying to place a point at the intersection of a vector and a surface. (This is assuming one exists.)  The vector will be determined by a pair of points.  Figure attached.I would welcome ideas!!See More

"Hi Neil, unfortunately it's very difficult. The [Trim Solid] component is supposed to do this, but it isn't working correctly. It seems that Rhino5 actually does provide tools for this, so I can fix the component, in the meantime I wrote…"
