From start to finish

Let us create a simple pattern together. We will use the individual functions step by step and work through the complete process in Seamly2D.

We will create a pattern for a basic panty.

Important note: This tutorial will show you how to use most of the tools available in Semaly2D. But it won't cover why to choose which numbers. Each pattern has it's own rules, which can be very different. There are several ways to build up your pattern, so you need to refere to those instructions (e.g. Winifred Aldrich, Müller&Sohn).

Note:

We will add the files here in the wiki once it's possible. For the moment we will link to the Seamly2D forum where we saved the documents

SeamlyME

First we will open SeamlyME and enter the measurements we need. In this tutorial we will use cm as unit and an individual measurement file.

◆

For this pattern we need several measurements:

• Waist circumference ⇒ 72 cm
• Hip circumference ⇒ 97 cm
• Waist to hip (side) ⇒ 21 cm
• Crotch length (front) ⇒ 26.5 cm

◆

Insert your own measurements. For this tutorial we will use the measurements as mentioned above. Delete the formula in the crotch length (N03) and insert your measurement.

After that you can save the mesurement file.

Seamly2D

Now you can open Seamly2D and create a new draft block by clicking on the New button. Give the draft block a good name.

◆

The next step will be to add the SeamlyME measurement file you just created. Now you can use those measurements.

◆ You can modify the name of your starting point to your liking. You may leave the default values or you can define the coordinates to even numbers, if you wish.

◆

We can now start drawing our first nodes. Select the Point - Length and Angle - Tool and click on point A to begin drawing. Move the cursor away a distance and hit enter.

Once you hit enter, a window will open where you can modify the properties.

• Make sure that the angle is set to 270°
• Select the formula tool for the length. We will choose our measurement crotch_length_f. If you misspell something or entered a wrong formula, the word error will show up. Amend the formula accordingly

Advice: You can read instructions for each tool in the bottom left corner of the screen.

Important note: Angles are measured anti-clockwise from 0 degrees (= horizontal to the right) to 360 degrees (= horizontal to the right)

◆

Zoom to fit all, so you can see the new node. You can also use the scrollwheel of your mouse

◆

We will continue creating 3 new nodes with the Point - Length and Angle - Tool

• Point: A ⇒ A2, Length: waist_to_hip_side, Angle 270°
• Point: A1 ⇒ A3, Length: hip_circ/10 -1, Angle 270°
• Point: A ⇒ A4, Length: hip_circ/4 -2, Angle 0°

◆ We will finish our pattern grid with a new tool: Point - Intersect XY. Click on point A4 and then on point A2. Repeat the same tool from point A4 to point A3. You now created points A5 & A6.

◆

Next we create different variables we can use later on. Variables are very useful. You can use them as an easily accessible place for things like ease where one can change the values in one place for the whole pattern.

• vertical_mark: 8 cm
• side_length_mark: 5 cm
• side_waist_drop_mark: 6 cm

◆

Go ahead a create two new nodes with the Point - Length and Angle - Tool

• Point: A ⇒ A7, Length: waist_circ/4, Angle 0°
• Point: A ⇒ A8, Length: #vertical_mark, Angle 270°

◆

We will create new nodes with a new tool. The Point - On Line Tool. Select the tool and click first on point A7 and then point A5. Choose the variable side_waist_drop_mark as length. Repeat by clicking point A9 and A5. The length for the new point is side_length_mark

• Point: A7, A5 ⇒ A9, Length: #side_waist_drop_mark
• Point: A9, A5 ⇒ A10, Length: #side_length_mark

◆

We will add some more variables.

• offset_front_to_back: 1.5 cm
• gusset_width: 3.5 cm
• gusset_width_offset: 0.3 cm
• gusset_fold_height: 2.1 cm
• gusset_height: 8 cm
• gusset_radius: 1 cm
• slope_offset: 1 cm
• curve_height: 7 cm

◆

Use the new tool Point - On Perpendicular . Click first on point A9 and then point A10. Choose the variable offset_front_to_back as length. Repeat by clicking point A9 and A10. The length for the new point is offset_front_to_back. This time change the rotation angle to 180°. For the next point click first on point A10 and then point A9. Choose the variable offset_front_to_back as length and 180° for the rotation angle.

• Point: A9, A10 ⇒ A11, Length: #offset_front_to_back, Rotation: 0°
• Point: A9, A10 ⇒ A12, Length: #offset_front_to_back, Rotation: 180°
• Point: A10, A9 ⇒ A13, Length: #offset_front_to_back, Rotation: 180°

◆

We will create again some new nodes. We will use different tools as shown below => Point - Length and Angle, Point - Intersect XY, Point - On Perpendicular, Point - On Line:

• Point - Length and Angle
  • Point: A3 ⇒ A14, Length: #gusset_fold_height, Angle 270°
  • Point: A3 ⇒ A15, Length: #gusset_fold_height, Angle 90°
  • Point: A14 ⇒ A16, Length: #gusset_width, Angle 0°
• Point - Intersect XY
  • Point: A15, A16 ⇒ A17
• Point - Length and Angle
  • Point: A16 ⇒ A18, Length: #gusset_radius, Angle 180°
  • Point: A16 ⇒ A19, Length: #gusset_radius, Angle 90°
• Point - Intersect XY
  • Point: A18, A19 ⇒ A20
  • Point: A18, A17 ⇒ A21
• Point - Length and Angle
  • Point: A17 ⇒ A22, Length: #gusset_radius, Angle 270°
• Point - Intersect XY
  • Point: A18, A22 ⇒ A22
• Point - Length and Angle
  • Point: A8 ⇒ A24, Length: #slope_offset, Angle 90°
  • Point: A8 ⇒ A25, Length: #slope_offset, Angle 270°
• Point - On Perpendicular
  • Point: A10, A9 ⇒ A26, Length: #offset_front_to_back, Rotation: 0°
• Point - On Line
  • Point: A19, A10 ⇒ A27, Length: CurrentLength/2
• Point - On Perpendicular
  • Point: A27, A10 ⇒ A28, Length: #curve_height, Rotation: 0°
• Point - Length and Angle
  • Point: A3 ⇒ A29, Length: #gusset_height, Angle 90°
• Point - Intersect XY
  • Point: A16, A29 ⇒ A30
• Point - Length and Angle
  • Point: A30 ⇒ A31, Length: #gusset_width_offset, Angle 180°

We now have finished marking all necessary points.

◆

Add some groups, so we can organize all nodes and show/hide them as needed. After that we will add all the points we created to the group Grid.

• Back
• Curves
• Front
• Grid
• Gusset
• Mirror_Rotation

◆ We will need some more reference nodes for the curves. Therefore will will change the name of the basepoint.

◆

We will create again some new nodes:

• Point - Length and Angle
  • Point: A24 ⇒ B1, Length: 6cm, Angle 0°
  • Point: A25 ⇒ B2, Length: 6cm, Angle 0°
• Point - On Perpendicular
  • Point: A11, A13 ⇒ B3, Length: 6cm, Rotation: 180°
  • Point: A12, A26 ⇒ B4, Length: 6cm, Rotation: 180°
  • Point: A26, A12 ⇒ B5, Length: 6cm, Rotation: 0°
  • Point: A28, A27 ⇒ B6, Length: 6cm, Rotation: 0°
  • Point: A28, A27 ⇒ B7, Length: 3cm, Rotation: 180°
  • Point: A31, B7 ⇒ B8, Length: 1cm, Rotation: 0°
  • Point: A31, B8 ⇒ B9, Length: 3cm, Rotation: 180°
  • Point: A31, B8 ⇒ B10, Length: 3cm, Rotation: 0°
  • Point: A22, A10 ⇒ B11, Length: 1cm, Rotation: 180°
  • Point: A22, B11 ⇒ B12, Length: 8cm, Rotation: 0°
  • Point: A27, A28 ⇒ B13, Length: 8cm, Rotation: 0°
  • Point: A27, A28 ⇒ B14, Length: 10cm, Rotation: 180°
  • Point: A13, A11 ⇒ B15, Length: 5cm, Rotation: 0°

You can hide all the points we added to the Grid group. So you will see only the new points. Add those to the group Curves. BTW: you can add/remove manually nodes to groups by rightclicking and selecting the appropriate function.

◆ Add some other base points to the Curves group and modify the linetypes as you see fit to better distinguish the different nodes.

We will use different tools to create curves. First we will use the tool Curve - Fixed. Click on the points A24, B1, B3 & A11. Repeat the tool by clicking A25, B2, B4 & A12. For curves with a more complex shape we can combine more nodes with the Spline - Fixed tool. Try it by clicking on points A26, B5, B6, A28, B7, B9, A31, B10, A19 & A19 (Yes click twice on A19 to finish the function or hit enter). Repeat with the same tool by clicking on points A13, B15, B14, A27, B13, B12 & A22.

◆

We will do the last curves with the Arc - Radius and Angles Tool.

• Center point: A20, Radius: #gusset_radius, First angle: 270°, Second angle: 0°

• Center point: A23, Radius: #gusset_radius, First angle: 0°, Second angle: 90°

◆

We have created all necessary nodes. It will be usefull to add all nodes and curves in different groups. Remember that you can assign a node to several groups

We now need to tweak the curves a little bit and check and align the transitions. For that we will use Mirror Object by Line Tool and mirror all node from the front part along point A9 & A10. With the mirror tool you can easily create new nodes, so you can verify the transition between different curves. If need to, you can adjust the curve nodes as needed to get a smooth transition between the curves.

◆ Congratulations! We have compeleted the first part in Draw - Mode. The next step will be to create a new pattern piece.

We will start with the nodes from front part. Remember to click all elements in clockwise order. It is also important to bear in mind, that each curve and arc has a flow direction. After clicking all the points, hit enter to finish the process. You can then specify the properties of the pattern piece. You can allways modify those properties by rightclicking on the pattern piece, if you need to.

◆

If you wish to, you can modify the generel pattern preferences and create a label template for your design. This information can be displayed in the pattern pieces.

Edit the properties of your pattern pieces as needed.

◆

The last step will be to layout your pattern pieces in Layout - Mode. Choose your pattern format and get the pattern pieces ready for printing. You can now print your pattern.

A Layout Image contains the final version of your selected pattern pieces as they appear in Detail Mode. It does not include internal hatch marks, points, or point labels.

Each Layout Image has a background size that determines how the pattern pieces will be placed, and how many sheets are included in the Layout Image. For your convenience, the Layout Image background size can be selected from pre-defined sheet paper sizes, roll paper sizes, or you can create a custom size. The background size is not required to be your printer's paper size.

The background size must be big enough to hold your largest pattern piece, otherwise this error message appears: "Several work pieces left not arranged, but none of them match for paper." . To print a Layout Image as a tiled PDF, the background size must be bigger than the size of the paper in your printer and must be big enough to hold all pattern pieces.

Sheet paper size: Best for printing multisheet Layout Images. Multisheets are displayed in the right-hand column of Layout Mode. (Example: Your multisheet Layout Image is A0 size. You select File/Layout/Print to print to your plotter which uses A0 paper.)

Custom paper size: Good option for saving and printing as tiled PDFs but requires time to find best width and length. Begin with width and length larger than you need and reduce to find best size

Review Dialog options before clicking "OK". Select your printer to reserve the correct border widths for printer margins Select Unite pages if possible to convert a multisheet Layout Image into a single sheet Layout Image. Select Autocrop unused length to reduce blank space in tiled PDFs.

Select File/Layout/Print if your single or multi-sheet Layout Image background size fits within your printer paper. Select File/Layout/Print as Tiled PDF if your single sheet Layout Image background size is bigger than your printer paper.

Note:

If your multi-sheet Layout Image background size is bigger than your printer paper, then you should recreate your Layout Image

Happy Seamly2Ding.
