Hull Design > Lines Drawings

A lines drawing is a way for you to communicate your three dimensional model created in Orca3D into a two dimensional format for others to view.

The Orca3D Lines Drawing command creates a new Page View within your Rhino file. The Page View contains 3 views of your model, one containing stations, one containing buttocks, and one containing waterlines. (For more information on Layout views in Rhino, see Rhino's documentation on the Layout command.)

Orca3D's Lines Drawing command contains options to add section labels, a border, a title block, and principal characteristics. These objects are all added into separate layers so you can turn their visibility on and off with ease.

Toolbar
Menu	Orca3D > Hull Design > Lines Drawing
Command	OrcaCreateLinesDrawing

Notes:

•	Make sure that you have created sections of your model using the OrcaSections command.

•	If you wish principal characteristics to be included, make sure that you have defined a Design Condition in the Stability section of Orca3D.

•	If you wish station annotations to contain station locations instead of station numbers, simply enter the most forward point of your hull for the Station 0 location, and type 1 as the station spacing.

•	When printing, if you wish your lines drawing to be printed correctly on the indicated paper size, in the Rhino Print Setup dialog make sure to select the printing scale as 1:1, and set the output color to display colors.

1.	Start the command with the toolbar icon, menu selection or keyboard command.

a.	If the following dialog box appears, then you have not created sections using OrcaSections. Please create sections before using the OrcaCreateLinesDrawing command.

b.	If this dialog box appears, then you have not defined a Design Condition. You may still continue to create the lines drawing, but if you wish to include principal characteristics in your drawing, you must first define the Design Condition.

c.	If this dialog box appears, then there was an error computing your Design Condition. You may still continue to create the lines drawing, but if you wish to include principal characteristics in your drawing, you must first define the Design Condition correctly.

2.	The Orca3D Lines Drawing dialog box will appear, with the Display Options tab selected:

3.	Select which curves to include; only Orca3D Sections, All Curves in the drawing, or you may select the specific curves to include

4.	Check any of the next six check boxes depending on what you wish to be visible on the lines drawing.

a.	In order to display Principal Characteristics, you must have defined a Design Condition before starting the Lines Drawing function

Station Numbering

5.	Type the location of Station 0 relative to the origin. This uses the units that your model is in, not the page units.

6.	Type the station spacing in the model units. The stations will be labeled with station numbers according to these values.

Section Label Options and Display Colors

7.	Enter the Label Precision and Label Text Size

8.	Select a color for each of the Section types (by default they are all black, so that they will show up well on a black and white printer)

The Print Options tab is shown below:

9.	Select the printer that has the paper size you wish to use.

10.	Select the Page size that you wish your lines drawing to be created on.

11.	Select the units for the page size.

12.	Select whether you wish the page to be in landscape or portrait format.

13.	If you wish to enter a custom page size, select the checkbox.

a.	If selected, enter your custom page size in the lower left; this is in the units selected previously.

14.	Edit the paper margins. They are in the units you selected above.

15.	Select either Fit to Page, or Custom Scale. Fit to Page will fit the three views of your model as best it can onto the paper size you have selected, whereas Custom Scale uses a scale of your choice.

a.	If you chose Custom Scale, enter the scale you wish to use in decimal format.

The Title Block Options tab is shown below:

16.	If you selected “Display Title Block” in the Display Options tab, you can edit the specifics of the title block here.

a.	Fill in all of the named items with the appropriate information.

b.	The bottom left and bottom right items are to be used at your discretion. They can be filled with whatever information you want within your title block.

c.	Enter a size for the Title Block text.

Your lines drawing is created using the information you provided. Notice that the diagonals are shown in their own planes, below the planview. The appropriate information has been included in the title block, as shown in the second figure below. The third figure shows a close up of the bodyplan, where you can see the section labels.

You will notice the objects in separate layers, as shown below:

You may turn off visibility, lock, or delete the layers as you wish to better manage your lines drawing.

The Layout and the Layer will be labeled with the time and date that the Lines Drawing was created. The drawing will be up to date with the model as of that time. Any further changes to the model are not reflected automatically in the Lines Drawing. You will need to create a new Lines Drawing if you modify your model.

In case the section labels overlap or you wish them to be in a different location, they can be easily moved. First select the section label you wish to move and zoom all the way in as follows:

Then turn the Rhino control points on by selecting the section label and either navigating the menu to ( Edit > Control Points > Control Points On) , typing PointsOn in the command line, or left-clicking the icon.

Next, select the right two control points, and move them wherever you wish the section label to be moved to.

To Finish, deselect the control points and turn them off by navigating the menu to ( Edit > Control Points > Control Points Off), typing PointsOff in the command line, or right-clicking the icon.
