 Design #01
Design Simple Hull :

1. New Design

2. Units

: Metres & Tonnes (Default)

3. Add Surface (Default surface)

4. Surface Precision (Medium)

5. Starting Design

: Size Surface

: Length : 25, Beam : 10, Depth : 5

6. Getting the desired shape

: Adding & Deleting control point rows

: Adding & Deleting control point columns

7. Fairing the Design

: Surface Properties

: B-splines, Long. Flex. : 5, Tranv. Flex. : 3

: Manipulate edges

8. Frame of Reference

: DWL : 3 m

9. Zero Point

: Set to Aft Perpendicular & Baseline

 

10. Grid Spacing

: Section : 11 stations (Evenly along the length of the model)

: add 1 section at the transom

: 3 Waterlines, 2 buttocks and 2 diagonal

11. Set Design Requirements

: Manipulate the control point net in all three views

          (can be viewed selected “calculate Hydrostatic”)

12. Parametric Transformation

       : Set the required value to 0,65 and constrain the waterline Length, Beam

  and draft (Lackenby method)

Exercise #01

 

# Set the frame of reference so that the zero point  is at the aft perpendicular and the baseline

# Define the grid so that you have a number of sections, waterlines and buttocks

¨Section : 11 stations (Evenly along the length of the model)

¨add 1 section at the transom

¨4 Waterlines, 3 buttocks and 2 diagonal

# Use the sample calculations provided to evaluate the volume etc of your design

# Manipulate your design to get a block coefficient (Cb) of approximately 0.65

 

Fairing

# Manipulating the design

# Use smooth and straighten controls

# Surface Properties

# Turn on the outside arrows toggle

¨Requirement for Hydromax & workshop

# Compressed View

¨Highlight any unfairness in the lines

# Rendering 

#  Check the hydrostatic

 

 

# Manipulating Surface

¨Resizing

¨Moving

¨Duplicating

# Bonding Surface

# Trimming Surface

# Aligning surface

Design #02

Design of a Chine Hull Using Multiple Bonded Surface

# New Design

# Units

¨Metres & Tonnes (Default)

# Create Topsides Surface (Longitudinal Plane)

# Surface Precision (Medium)

# Size Surface

  Length : 40, Depth : 3, Beam : 10

# Add 3 control point columns

# Surface Properties

  B-splines, Long. Flex. : 4, Tranv. Flex. : 2

# Move Surface

  Set tranverse distance 5 m

# Control Properties

  Close the bow by set the offset value to 0 m

# Create a Chine surface

¨Duplicate surface (Topsides surface)

  set the vertical spacing edit box to -3,5 m

# Bond two surfaces

  Select 2 control point from 2 surfaces (Topsides & Chine)
