Specifies open or closed curves in the order in which the surface or solid will pass through them. Specifies first or last point of the lofting operation. If you start with the Point option, you must next select a closed curve. Handles multiple, end-to-end edges as one cross section. Controls whether the lofted object is a solid or a surface. The onslaught of epoxy changed everything about boat building.

Options for building a boat are now plentiful and at times confusing for the home builder. For example, a small rowing craft can be built in wood strip, stitch and glue, lapstrake, carvel planked or cloth over frame.

Each boat coming from the same original design. The one thing they all have in common is they need to be lofted by somebody. The History of Lofting you need to know this. There are a couple of things to know about lofting before you learn to loft. One fun fact is the origin of the term lofting. In days gone by before computers , lofting needed to be done near the boat building effort as the builders needed to frequently check lines and measurements.

Because the building site was both busy and dirty, lofting the boat on the building floor was far from perfect. Most of these boat shops did however have lofts in them where the drawing typically took place. You can probably see where we are going with this. The term of lofting originates from the location it was practiced. The next thing you need to know is how the numbers are represented in a table of offsets.

In the table of offsets you will typically see entries for half breadths, depths, profiles and sheers and they are represented by numbers that look something like this. Typically it depended on the size of the boat as to whether or not feet were used and each designer has their own preference, both methods yield the same result. If you are wondering how this method of lofting was settled on, it is simpler than you think.

First, when boats began to be lofted, the imperial numbering system was most prevalent. The metric system, though invented in the late 17th century, was not adopted as a standard unit of measure by any country until when France adopted it as their standard measuring system. Great Brittan and the United states which are arguably the two largest ship and boat building countries of the last years did not adopt the metric system until the mid 's and in the U.

By that time many a boat had been designed, lofted and recorded and there is little urgency to change a system which has so much history and works so well. Remember that boat designs are not meant for one geographic area so unless someone gets the urge to re-loft and re-publish the thousands of boat plans already published, the system is in little danger of being toppled. More importantly, you would be doing yourself a disservice by not learning the measuring scheme as there are so many boat designs published using the system.

The Essential Terms. Many people get confused at where the line is between boat building and lofting and there is good reason for this, the two are interdependent. You cannot loft a boat without knowing something about boat building and you cannot build a boat unless someone has lofted it out first. As an example, you don't need to know how to mount a sheer clamp in order to loft, but you sure need to know what it is if you are going to loft it.

Little wonder why pretty much all small craft lofters are also small boat builders. We will use some boatbuilding terms as we go, however the essential terms for lofting are actually very few.

We should start with the views. Boats are lofted in 3 dimensions, 2 dimensions at a time. There are 3 views, each view giving two dimensions. Each of these views could be mapped to the Cartesian coordinate system, however historically neither the X,Y or Z axis has been assigned to any view.

In using newer CAD systems, however it is required to assign a planes to each view and I imagine that different designers assign different planes. Don't get too hung up on this concept as it is not even relevant unless you are using a computer to loft your boat and if you are using a CAD system, the concept is probably not foreign to you. Plan view: This is the view of the boat looking down from the sky.

On one side you will see the lines of the boat. On the other side of the plans view you will see what is basically a sketch of the boat. Filter by Lables. Message 1 of 5. Bill Swann. Lofting a boat hull. I was rather pleased that I could loft a boat hull. Then I was able to create the ribs by using the project edges tool to make the shape.

I wonder if anyone does this professionally with inventor? Preview file.
