to installing and upgrading to version 3.20 of Speedstack,
ensure all current work, stackups, projects, libraries,
filters are fully backed up to a safe location. For a
default installation Polar recommends backing up the
entire contents of the Speedstack folder (C:\Program Files\Polar\Speedstack).
If you are upgrading from a version earlier than
Speedstack version 2.0 please contact PolarCare for upgrade
Speedstack 2008 v3.2 includes parameter unit
switching (between microns, mils, millimeters and
inches). This note describes the upgrade and unit
conversion processes when Speedstack 2008 v3.2 is
started for new installations, upgrades
form earlier versions and subsequent launches.
installation first launch
a "defaults" file
For a new installation, on first launch Speedstack
generates a "defaults" file. This file
contains one collection of default settings (general
settings, goal seek parameters, Stack Editor and
Autostack settings, user information, screen colors,
library and stackup file locations, etc.) Subsequently,
parameter can be set in one of the four primary units.
This allows for different defaults to be set for each
unit. As the current units are changed the defaults are
shown in the current units in the Tools|Options|Configuration
When a user selects units Speedstack:

The files set up (above) on first launch are opened

of existing Options File
This will be carried out automatically with only the
input of the units employed in the file.
The original file will be retained under its original
name while the new file will have the suffix “.inix”
to signify that it is in XML. The defaults for the other
three units will be set as if this was the first run.
The current unit will be as chosen for the 'inix'
The old default library will be loaded as the
application starts.. As with the options file the new
units will be requested. The library will then be
converted to microns and saved. The library when being
edited/reviewed or used to select materials will display
the library in the current units. Material from metric
or imperial data sheets can be stored in the same
library, but will be displayed in the current units. See

no project is loaded or displayed.
Projects can be opened as normal, but for legacy
projects it will be necessary to convert the units used.
Upon opening, the project will be displayed and the user
asked to enter the units that the project was saved in.
The project will then be converted from those units into
microns and displayed in the current units. The
converted project will then be saved with the original
file name while the old project will have an additional
suffix (“.3v0”) to differentiate it. Once the user
has confirmed correct conversion the old file may be
The application will start up in the units which were in
use when it closed
The application will open the project which was last
opened before closing the application (provided the
option to do so has been selected under Tools/Options.)
