  1. Floyd (fnkershner), I would be happy to provide some Sketchup coaching for your project at no charge. I am a retired professional educator and enjoy helping people learn new things. What you want to do utilizes just basic functions of Sketchup. Solid objects created in Sketchup are inherently manifold and 3D-printable unless you break the envelope or introduce extra geometry in an uncontrolled fashion. Please PM me with your email address if you are interested. Terry Colorado Springs, CO
  2. Here is a quick-and-dirty build of Galilee's hull I did in Sketchup a number of years ago using an old set of plans I developed back in 2002. Just wanted to see how it would work to display hull form. Unlike parametric 3D programs and for-the-purpose naval architectural software (e.g., DELFTShip), the result shows distinct polygons when you display hidden lines. It is also a lot of work creating the intersections at stations and waterlines. Terry
  3. Here is the instructional PDF for creating sockets in 3D objects. Please let me know if there is anything that is unclear, and I will try to explain it. A real power-user of Sketchup may be able to come up with a quicker method. I've been using Sketchup almost as long as it has been around, and I'm afraid I've become entrenched with some habits picked up years ago. Terry Creating the Hub of a Ship's Wheel.pdf
  4. Sailor1–0, How familiar are you with the Intersection feature of Sketchup? You might want to try creating models of the wheel hub and spokes, individually grouping each element and arranging them as in the final object. (Save a copy of a spoke for later.) Then explode the hub and intersect the spokes with it to define the spoke cutouts in the hub. Regroup the hub, then explode the spokes. Intersect the hub with the spokes to define the spoke socket walls inside the hub. Delete all of the spoke components except for the parts that lie inside the hub. Explode the hub and delete the surface areas inside the spoke sockets. If the work is done carefully, the hub now is solid volume with the spoke sockets arranged where they need to be. If needed, recreate the spokes from the copy and insert them into the hub. The process is somewhat complicated but straightforward. I can provide a PDF with images of the key steps if that will help visualize the process. Terry
  5. how many of you are a..

    The voting tool needs to allow more than one choice. I have the privilege of completing three of them.
  6. Status update:


    Finished house renovations—check

    Sold house in Greenville, SC for nice profit—check

    Loaded 26-foot Uhaul truck and drove 1500 miles to Colorado Springs, Colorado—check

    Moved into a 1-bedroom apartment; temporarily stowed the rest of our stuff in two storage rooms—check


    Sadly, there is no shop and all my tools are packed away. Will try to get back into working on my Galilee plans soon.

      Bought a quaint two-story house in Colorado Springs, Colorado, USA with a 400-square foot (~37 m²) garage. The down side is that the garage has only one outlet and one light bulb (and a lot of remaining boxes).


      As we get the painting and other move-in repairs accomplished, I will be taking time to rewire the garage so that I can actually do some work in it.

    The 635 boat is now a Moored Training Ship in Charleston, as you well know, Don. My last duty station before retiring.
