Remember that your drawings are build consecutively. So you can't delete any point if those were used as a base point for other tools. And you can't use points for other tools if those point were created after the base point
The drawings in Seamly2D are formula driven. Each point, each line depends on a point created before. Instead of drawing one drawing with fixed values, you will use your measurment file. So if you change your measurements, the drawing will follow accordingly.
The Draw Mode is designed to allow easy adjustment of a pattern to suit particular wearers. It is therefore entirely formula-based, where the simplest formula is a set figure.
Import note:
The one immutable fact of the application is that any given tool only has access to tools that were previously created. This means that your first point can't reference the last point. But the last point can reference the first one.
A pattern is a collection of pieces, prepared individually. Drawing a pattern starts from a reference point. Construction lines are defined from there, until sewing lines are defined.
Most lines are defined by one or more points, and occasionally angles.
Important note:
These are measured anti-clockwise from 0 degrees = horizontal to the right.
How to start
Before you start a new drawing you first need to create a new drawft block.
You can do so:
by clicking the New-button
or hit F2 to Rename Draft Block
You need to define a new name and a unit for you draft block
Once your first draft block is created you can change to the different working modes. For now we stick with the draw mode
Overview
The screen is divided in different areas. You can rearrange some palettes and show/hide different toolbar as you wish.
Toolbar (1)
All the tools you can use. For further details have a look here: Seamly2D Tools
Property Editor (2)
The Property Editor is super handy. You can change all the properties of the selected element, such as the name, a given lenght, a formula, etc.
The properties may vary depending on the tool selected.
The name of the new point must be unique. Seamly2D wont let use choose a name twice
Group Manager (3)
The Group Manager will help to structure your drawing. You can group elements and show/hide them as need. So you can focus on special parts of your drawing. You will need a lot of points, lines, curves for advances pattern, so it's great you can focus one some of them and hide the rest.
You can add as many groups as you wish. Click on the +-button to add a new group. Enter a unique name and choose a color, linenweight and linecolor.
For now, the line properties do not have any impact. This may change in future versions of Seamly2D
You can show/hide and lock the group as you like. Locked groups can't be modified.
You can sort the list by clicking on the different headers
V (visible) ⇒ sort by visibility
L (locked) ⇒ sort by lock status
O (group contains elements) ⇒ sort by flag
Name ⇒ sort by name
If a group is selected, you'll the a list of objects in that group
Base name (4)
You can the select the base name of new point out of a list. Each new point will be numbered automatically, such as A1, A2, A3, ... Different base names will help you identifying the meaning of the points/lines
Current Line Properties (5)
You can set the line properties for new lines whcih will be created. Existing lines are not affected by these setting. User the Property Editor to modify existing elements
Drawing Area (6)
The main area of Seamly2D. Here will will draw your pattern. You can zoom and pan with you mouse or tools from the toolbar
Important note:
Remember that your drawings are build consecutively. So you can't delete any point if those were used as a base point for other tools. And you can't use points for other tools if those point were created after the base point
