STEP 3: Set up loft profiles
1. Right Hand Side
Test the layers. In Design Director (DD), hide a layer - you should see 3 corresponding curves disappear, which is really the one curve projected onto the 3 planes - plan, body and profile.
There are a lot of lines here. If I was me, I'd chuck some. Keep a good accuracy near the busy areas of bow and stern, but throw away lots of stuff in the middle.
Delete station layers to keep only the following;
3. Spline Dividers
We are working almost exclusively with station lines, as these will form the section profiles for the hull loft. Turbocad is happiest when it has the same number of points for each loft profile (station). To help us do this we will sketch some radiating lines on the Body plane (amidships). We will use 12 points per section, which means 11 dividing lines radiating from the top centerline (Drawn in blue here - directly onto the Body workplane). The radiating lines are concentrated at the bilge radius to improve resolution at that spot.
Notice the vertical line set at the bow stem thickness (12th line). This will become the loft inside limit - which leaves a gap between LHS and RHS of the hull. The keel and stem will be added later as a separate object.
Pretty isn't it? Trouble is I forgot to tell you to put them on a new layer. Sorry... just kidding. CAD isn't this cruel. Now for our next trick....
4. Whoops. How to move stuff to another layer.
(This could come in handy!)
5. Splines setup
Each station curve (body line) will be a spline. In Turbocad we can set the mathematical resolution of spline. The default is 20 points between each control point (node), but we will reduce this to make the curves smoother. (Bit silly to have station control points so close together if the stations-to-station distance is so much larger).
Use the standard Properties Dialogue to get at the object's Properties (Like you do for everything else in TC). There are lots of ways to get to it;
From the Main Menu choose Format| Properties.
