Here at first more of the tools and icons are in disable stage, they will be enabled after you make the first piece by the following process

Fig, 7 How to create a piece/pattern

Icons and Tool Bars: Now after creating the first piece the icons and toolbar will be enabled, so let’s see different toolbars and their functions.

Fig 8, Insert toolbar


Insert toolbar is mainly used for internal drawing, there are different types of a shortcut which will be used by professional for designing

Point On Contour (Shortcut Key 0)

Use the Point On tool to add a point onto the perimeter of a piece. You can also decide on a point type when adding the new point.

Process

Select the POINT ON contour > add a point along a line or segment [ Click the mouse button ] > point attribute window will open[ it allows the user to specify a distance from the previous or next point ]> enter a value, then ok> the repeat the steps from adding a point

Notch

Use the Notch tool to add a notch to a piece’s perimeter. This tool provides an easy way to add or edit notches once the digitizing process is finished. A notch is a marking point positioned on the boundary of a piece.

To Add a Notch:

  • Select Add a Notch > Add a Notch to a segment [with shift select existing notch, with +ctrl add a point only]
  • Note for a notch on the partculer point, create the point first. another wise notch will be created on the mid-point of the perimeter.
  • Note 2: To change the shape of the notch, click the preference [\ key]>notch. Notch type, click here and change the shape> apply> ok

Seam

Use the Seam tool to add a seam allowance to piece.

To Add Seam Allowance:

  • Select the Seam Allowance tool.
  • Either select a point on a piece indicating that seam allowance is to be added to the entire piece, or select the segment on the piece on which to apply for a seam allowance.
  • To select a single point for adding a constant seam allowance to the entire piece, point the Seam Allowance tool at a point on the piece and click the mouse twice.
  • To select a segment or multiple segments, point the Seam Allowance tool at the first point and click the mouse, then drag the Seam Allowance tool to the last point of the segment and click the mouse.
  • When the Point Attributes dialog box displays, enter the amount of the allowance in the Seam Width box at the lower left of the dialog box. If the seam allowance is added to the entire piece, select the appropriate corner type by clicking on the corresponding corner icon. If the seam allowance is added to a segment of the piece, choose the type of corner to apply to the start of the seam and to the end of the seam from the Start Seam/ End Seam boxes. The icons illustrate available corner types. To leave the corner types as standard corners, it is not necessary to make a corner selection.
  • Click OK after appropriate information is added.

Dart

Darts are based on four points. If the dart is digitized, the Start, Middle ( the overlap extension) and Endpoints are on the piece’s boundary. The fourth point is the apex of the dart and is digitized while defining the dart. Just below the apex, the drill hole should also be indicated.

The first point of the dart is placed on the pattern contour by pressing the letter ‘D’ on the 16-button digitizer. The second point is placed internally at the apex of the dart. The other two points are automatically inserted.

!Note: See the File Chapter for details on digitizing a dart.

!Tip: If a dart is not digitized during the digitizing process, it can easily be added to piece on the screen using the Dart tool.

To Create a New Dart:

  • Select the Dart tool.
  • Click the left mouse button on the first point of the dart (See the diagram below).

!Note: There must be existing points on the first and last dart points on the piece’s boundary. If points do not exist where the dart is to be placed, use the Add Relative command in the Edit menu. (See the Edit chapter).

  • Click the left mouse button again on the last point of the dart. The cursor automatically becomes the center point (apex) of the line created between the two selected points.
  • Drag the cursor internally to create the dart depth and click the mouse button a third time. After clicking the mouse button a third time the Dart Attributes dialog box will appear.

!Note: The dart is always created symmetrically.

  • When the Dart Attributes dialog box displays, select the desired options.

Click OK.

Direction

Select the direction to fold the dart, clockwise, or counterclockwise. The Overlap box below must be checked in order to select a direction.

Overlap

Check the Overlap box to establish that the dart is to be folded in a specific direction. Checking this box activates the Direction options above.

Depth

Use the Depth field to view the current depth of the dart or enter a specific depth for the dart.

Pleat

The Pleat tool is used to create pleats. Both Box pleats and Knife pleats may be added using the Pleat tool. The Pleat tool allows for even and variable (uneven) pleating. Pleat depth and the amount of spacing between each pleat may also be specified in the Pleat dialog box.

!Note: Error messages appear if a pleat is placed over a sharp curve or corner. Error messages also appear if the number, depth, and distance between each pleat exceed the existing piece’s dimensions. Error messages indicate that the values entered into the Pleat dialog box are incorrect.

To Make a Pleat:

  • Select the Pleat tool.
  • Click the mouse on the piece at the point where the pleat is to start.
  • When the Move Point dialog box displays, either confirm the values in the Move Point dialog box by pressing Enter, or enter the desired values and click OK.
  • Click the mouse on the piece at the point where the pleat is to end. Repeat step 3.
  • When the Define Pleat Characteristics dialog box displays, enter the desired pleat information. (See the Pleat Characteristics Dialog Box section below).
  • Click OK.

Circle (Shortcut key CTRL +ALT +C)

Use the Circle tool to create a circular line on a piece. Circles may be created with a specific radius, and they may also be duplicated.

Process:

  • Select the Circle tool.> select the location for the circle center> move the mouse pointer to define the radius[ for the approximate size of the desired circular line ]> repeat the process for a new circle
  • Note: If you want to change the radius, Double click on the circle> circle properties windows open at the left side> Enter the new radius whatever you want> enter.

Button (Short cut key CTRL +ALT+B)

Use the Button tool to create drill holes. Buttons are also used to mark a match point.

The process to Create a Button (drill hole):

  • Select the Button tool > insert a button (click by mouse)>add button relative to the selective point window open> enter a value if you want to move the point> ok
  • Note: If you want to change the radius, Double click on the button> button properties windows open at the left side> Enter the new radius whatever you want> enter.
  • Note 2, If you want to drill it, Double click on the button>button properties windows open at the left side> click command in plotting and cutting attribute> choose drill> enter.

Text (Short cut Key ‘T’)

Use the Text tool to add text. This tool is commonly used to add instructions or other information to a piece to aid the cutting process.

The process to Place Text:

  • Click the Text tool> add text to a piece> Click at a position where you want to add text> text window open, enter the text> click ok Then repeat the process for adding a new text.
  • Note: If you want to change the size, double click on the text you enter, text properties window open> change the size and ok.

The process to Move a Single Point:

  • Select the Move Point tool > Select point for the move (Ctrl – not add a new point, shift -add curve point)> click on the outline and drag it to move the point to the desired position, release the left click > move point window open, enter the value and ok
  • Note: For a curve area, after clicking the move point tool, press shift and continue the point making the process.
  • Note 2: If you don’t want a new point then click CTRL key after clicking move tool and continue the point making process.

Draft

Use the Draft tool to draft multi-point internal lines.

To Draft a Line:

  • Select the Draft tool.
  • Click the mouse anywhere on the selected piece.
  • When the Add A Contour Relative To Current Point dialog box displays, enter specific values for exact placement of the point

or select OK to bypass this dialog.

  • Repeat Steps #2 and #3 until the desired line is constructed.
  • To finish drafting the line, click the right mouse button and select Finish Draft from the pop-up menu.

!Tip: To create a curved cut line, hold the Shift key down when clicking the mouse to select a point.

Flip Horizontal

This command flips the current pattern piece 180ø along the Y-axis (Back and Forth).

Flip Vertical

This command flips the current pattern 180ø along the X-axis (Up and Down).

Move Internal

The Move Internal tool is used to move any internal element, lines, buttons, circles and texts on a pattern piece.

To Move an Internal Element on a Pattern Piece:

  • Select the Move Internal command.
  • Click on the internal element to be moved. The internal element is now attached to the mouse and can be moved in any direction.
  • Move the internal element to the desired location.
  • Click the mouse button a second time to anchor the piece at the new location.

!Note: You can also copy internal elements to any location on the pattern by using the Shift + move Internal tool.

New Base Line

This command is used to edit baselines that run off a piece. Sometimes baselines move to the outside of the piece while working with the Cut tool or using the Create Parallel to Segment command.

This command is useful if the baseline was not digitized, or if two pieces were joined resulting in an odd shaped piece. This command places the current baseline inside the piece close to the center.

!Note: The length of the baseline may change during this process.

To Make a New Baseline:

  • From the PIECE menu choose to MAKE NEW BASELINE.
  • The Baseline is placed closer to the center of the pattern piece.

Mirror

This command creates a new piece exactly the same as the selected piece except the new piece has two symmetrical halves made from the original piece. Note that this command creates an exact symmetric duplicate, which is the same on both sides.

To Mirror a Pattern Piece:

  • Select two consecutive points by clicking on the first point, then dragging (clockwise) to the next point.
  • From the PIECE menu choose MIRROR.

A new piece is created which is symmetrically placed according to the selected points. The new piece displays in the furthermost right-hand box in the Piece Display Bar. See the diagram below.

Create a Parallel

Create Parallel is used to create a parallel segment from a selected section along a piece’s perimeter. Create Parallel allows the user to define the width or length of the segment as well as decide if the segment should extend to the piece’s perimeter. When the endpoints touch the perimeter, the Internal Cut tool may be used to split the piece along the new parallel line.

To Create a Parallel Segment from an Existing Section:

  • Click and drag the arrow in a clockwise direction to select the desired endpoints on the segment to Parallel.
  • From the DESIGN menu choose to CREATE PARALLEL.
  • Enter the values for the width or length of the parallel segment in the Create Parallel To Segment dialog box. The system allows the user to extend the first and last point of a new line by checking this option.
Fig 10, Some windows command

Set Half

Use the Set Half tool to create a symmetrical image of a piece. This is a very powerful tool, which is used on almost every PDS file. When a piece is halved, all actions performed on the original half are applied to the other half. Unlike the Set Mirror Line Tool, you can work only on the ‘real’ half – and not on the ‘reflected’ half, which is represented as a grid of lines. Using Set Half is almost always preferable to using Mirror Half, mainly because Optitex 3D recognizes the halved pieces, and saves considerable time by allowing you to stitch only half of the stitches. Although we recommend keeping it in view, you can hide the reflected half through the View & Selection option.

Icon & Location

  • Menu: Piece > Modify > Set Half
  • Toolbar: Edit
  • Toolbox: Half Symmetry

To use the Set Half tool:

  1. Select the Set Half tool.
  2. Click on the first point on the piece:
  3. With your mouse, move to the last point and click with your mouse.

    The piece is halved.

    The symmetric half is shown as a grid.

    When changing the geometry, by moving a segment of the contour of the ‘real’ half. The geometry of the reflected half is changed as well.


Internal Objects Inside Half Piece

When adding an internal object (an internal contour, button, circle, etc.), it also appears on the reflected half, unless the Reflection field is disabled in the Internal Object Properties.

Creating a Curved Angle on The Symmetry Line

When setting a piece to half, you need to use the Arc Tool
