Individual measurements[edit | edit source]
Standard measurements[edit | edit source]
Standard measurements tables contain sizing information which Seamly2D uses to calculate body measurements for standard-sized figures. It is important to bear in mind that, for the calculations to work, the body measurements must grow proportionately from size to size. However, people of different genders and ages (e.g. babies and toddlers, children, women, men, etc.) grow in different proportions. Therefore, you must provide a separate table for different genders and age groups.
Usually multi-size standard tables provide a lot statistical data that are hard to describe and require more than just the one column in the individual measurement file. Instead, you provide measurements for a default standard figure and allow Seamly2D to calculate the rest. To designate the default standard figure, specify a base size and a base height for your standard measurements table. Two values, size and height, uniquely identify standard-sized figures.
By size we usually understand value of chest measurement. According to our internal system of names, it is measurement G04 - Bust circumference (bustcirc). See page Measurements.
Height values grow in 6 cm and increments are limited to the values listed below.
Height (cm): 50, 56, 62, 68, 74, 80, 86, 92, 98, 104, 110, 116, 122, 128, 134, 140, 146, 152, 158, 164, 170, 176, 182, 188, 194, 200.
Size values grow in 2 cm and increments are limited to the values listed below.
Size (cm): 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72.
The format supports values described in two units: centimeters and millimeters (Inches aren't supported). Convert values described above to millimeters to get appropriate values if you use millimeters in your your table.
Usually, the process creating a file with standard tables requires specifying a base size, a base height and units of increment, then specifying a base value for each measurement. In other words, a column for this size and height you selected as a base. To enable Seamly2D to generate measurements for other size-height combinations, you must provide a size_increase and a height_increase for each measurement. The size_increase is the amount Seamly2D will add/subtract to the measurement's base value for every step up/down in size. Likewise, the height_increase is the amount Seamly2D will add/subtract to the measurement's base value for every step up/down in height.
Let's take a look at some examples to understand how it will work...
Here is an example of how Seamly2D would calculate a measurement after a new size and height combination has been selected:
distance_between_consecutive_sizes = 20 mm
distance_between_consecutive_heights = 60 mm
// Base values for a table:
base_size = 500 mm
base_height = 1760 mm
// waist girth:
base_value = 780 mm
size_increase = 40 mm
height_increase = 0 mm
// Change size and height:
new_size = 560 mm
new_height = 1880 mm
// Calculate the number of steps to go from the base size to the new size.
size_coefficient = ( new_size - base_size ) / distance_between_consecutive_sizes
= ( 560 - 500 ) / 20 = 3
// Calculate the number of steps to go from the base height to the new height.
height_coefficient = ( new_height - base_height ) / distance_between_consecutive_heights
= ( 1880 - 1760 ) / 60 = 2
new_measurement_value = base_value + size_coefficient * size_increase + height_coefficient * height_increase
// Calculate new measurement value for waist girth:
new_waist_girth = 780 + 3 * 40 + 2 * 0 = 900 mm
Let's look at a simpler example:
![](http://static.miraheze.org/seamlywiki/b/b7/Aldrichtable.png)
Here we see a table that has a correlation between measurements at different heights. The next thing, that we need to do to continue to work with it, is to designate the base size and base height. In this example, we will take size (chest measurement) 50 and height 80. All measurements in the column height 80 are now our base values. Then we calculate the values size_increase and height_increase for each measurement separately. In this example, the table only provides changes for heights. So, size_increase will be always equal to 0. The last thing to do is to find the height_increase values. Here are several examples for better understanding:
chest = 50, 52, 54 = 2. 50 + 2 = 52. 52 + 2 = 54
waist = 47, 49, 51 = 2
shoulder = 6.2, 6.6, 7 = 0.4
body rise = 14.1, 14.9, 15.7 = 0.8
Using measurements[edit | edit source]
To use the measurements, it should be linked to a pattern file. By default, each new pattern file isn't connected to any measurements. To understand current state take a look at window title. It will have the measurement file inside '[' ']' if one was connected to pattern, like this: pattern.val [measurements.vit]. Alternatively, you can use menu Pattern piece -> Pattern properties.
To create a measurement file, use the SeamlyMe app.
To link new measurements to the pattern file, use menu Measurements -> Load Individual ... or Measurements -> Load Multisize (Standar)...
Individual measurements[edit | edit source]
Files containing individual measurements end with suffix .vit (Seamly2D Individual Measurement).
Standard measurements[edit | edit source]
Files containing standard measurements end with suffix .vst (Seamly2D standard table). These files must reside in a specific folder for Seamly2D to find them. Seamly2D will look for the files in the following order:
- For Unix(Linux):
- [path to Seamly2D binary]/tables/standard
- /home/[user name]/.Seamly2D/tables/standard
- /usr/share/Seamly2D/tables/standard
- OS X:
- [path to Seamly2D bundle]/Resources/tables/standard
- [path to Seamly2D bundle]/tables/standard
- /home/[user name]/.Seamly2D/tables/standard
- /usr/share/Seamly2D/tables/standard
- Windows:
- [folder where Seamly2D.exe resides]/tables/standard
The paths mentioned above can be rewritten by changing the settings in Preferences. See page UserManual:Configuring Seamly2D
If a pattern is connected to standard measurements, to determine which standard figure is currently associated with your pattern, look at the values of size and height displayed at the bottom left of the main window. You may modify these values independently using the corresponding drop-down lists.
