Starting, saving and loading scenes and models

Starting, running and exiting Spacedraw

Once you've installed Spacedraw, you can start it like any other Android application from the apps-list, or by opening a .spa-, .spah- or .obj-file (see below) from a file browser.

There always runs only one instance of Spacedraw on a device; if you open a file with Spacedraw and it is already running, it is brought to front, and asks you to save unsaved changes to the currently loaded scene if necessary.

To send Spacedraw to the background and return to the home screen or previous application, NEW double-tap the back-key; Spacedraw will be kept in memory and brought to front again if you tap its icon in the apps-list or task-switcher.

To exit Spacedraw and free the used memory, invoke exit from the F-menu; the current state is saved to the disk and restored when you restart Spacedraw.

Using files

The current state of a scene can be saved to a file, with the paid version of Spacedraw optionally including the complete construction history. It includes all geometry in the scene, the material definitions, and the current selection, settings and active tool, so you can continue working on a project exactly where you left off when saving. In the free version of Spacedraw, only scenes with no more than 1000 vertices can be saved.

These scene-files are saved with a .spa-extension, or .spah-extension if construction history is included.

Models can be saved and loaded in the Wavefront .obj format that can be read and written by nearly every 3d-graphics program; texture coordinates, normal definitions, smoothing groups and materials are imported and exported. In the free version of Spacedraw, .obj-files can only be exported from scenes with no more than 1000 vertices.

All commands for managing scenes and loading and saving files are found in the F-menu.

to start a new scene, invoke new scene; an empty scene containing only one light is created, and all settings are reset

to open a scene, or load a .obj model in a new scene, invoke open, browse to the .spa-, .spah- or .obj-file and tap it; loading large files can take some time

to merge a saved scene with the current one, or add an .obj model to the current scene, invoke merge

to save the current state of the scene, invoke save or save as

to save models in the .obj-format, invoke export as .obj; the file-browser and text-input are shown; navigate to the folder where the file shall be saved and type the name, then use the enter-key or “OK” button to approve. The material definitions are stored in an equally named .mtl-file in the same folder, and all used texture image files are also copied to that folder if necessary.

The file-browser

For opening and saving files, the file-browser is displayed in a panel and lets you browse your device’s local file system

to navigate to the parent folder, tap the header

to open a subfolder, tap it

to navigate back, use the back command from the ribbon; the back-key closes the file-browser

to change the sorting, use the options from the ribbon

to create a new folder invoke new folder in the ribbon; the text-input appears; type the name and approve with the enter-key

to delete a file or empty folder, slide rightwards on it; a confirmation dialog appears
