UI Elements description (see website main base for basic workflow)
1.1. Cursor in 3d scene, using in drawing/kitbashing
1.2. Plane on which you draw
1.3. Camera navigation buttons and control (to hold and drag them)
1.4. Plane position button and control (to hold and drag them)
1.5. Mesh that drawn (example) using 3d brush tool
1.6. Current scene file path and statistics
1.7. Trajectory settings
1.8. Symmetry during drawing settings

2.1. File panel to import/export .obj-s (see FAQ for more info).
2.2. Free/Pro info
2.3. Quick save to current .obj file
2.4. Pallete to choose vertex color of new strokes. Using very rarely because it's program mostly for geometry, not colors
2.5. Alpha maps generator mode. This is generator that using brush presets to make pattern. When enables, also change image settings to special mode that useful to black and white alpha maps.
2.6. Image export and 3d view settings
2.7. Record program window to image sequence
2.8. Scene panel with list of separate meshes in current file

3.1. Welcome screen open button
3.2. View tool. Hide unnecessary ui elements, disables drawing and can be used just to view result model.
3.3. Move tool for selected object. Also has button to quickly centrify it.
3.4. Rotate tool to rotate selected object. Has buttons to quicly rotate at exact or random degrees.
3.5. Scale selected object tool. Has buttons for quick scale by exact multiplier
3.6. Modify selected object. List of actions and buttons for some them at top of panel
3.7. 3d brush (current tool). Main tool.
3.8. Surfaces of revolution drawing. Very intuitive tool that rotates drawn trajectory around axis to make surface. Has settings to make non-round sections.
Some tools that works as generators (Not AI)
3.9. Plants generator. Procedural tool, don't using drawing. Has a lot of parameters, also makes (optionaly) vertex colors that exports as special texture (see file menu for details)
3.10. Variants generator. Procedural tool that makes few different objects from single object or from group of them. Can be very useful to make kitbash sets.
3.11. Buildings generator. Procedural tool which that makes houses (usually in fantasy/futuristic style)
3.12. Deform using nodes. Useful if you want to make some deformations to mesh without export to another software. Make nodes, attach mesh to them and deform.
3.13. Basemesh generator for creatures. Also can be used for robots (because nodes can be replaced with meshes from 3d brushes)
3.14. Settings of program. UI size or colors, for example.
3.15. Info menu to open tutorials etc.

4.1. Brush radius and other settings
4.2. Boolean (beta). Expiremental tool
4.3. Embedded brushes to make most simple basemeshes
4.4. Last brushes that was used
4.5. Actions with brush presets: save, add new, copy
4.6. Return to overall brush library with all categories
4.7. Current category of brush presets
4.8. Brush presets, double click on preset opens it's settings (panel 6.x)
4.9. New preset menu to make brushes
4.10. Sub-categories can be created by user, presets can be moved between categories. Also can be collapsed/opened in ui.
4.11. Presets separators. All presets are separated to Embedded Presets, User presets (that created at current machine), Arseniy Korablev presets (huge amount of presets) and Other users brushes that stored at current machine but created on another.

5.1. Current object selected in objects list.
5.2. References menu to use images files in scene use as references.
5.3. Actions with objects: new, copy, merge, more(menu), clear, delete and a couple buttons which scale whole scene.

6.1. Drawing preview of selected brush preset. Click on preview opens larger 3d preview.
6.2. Brush type. It means what to do basically with mesh inside brush: use it as section/copy by trajectory/place one time/stretch by trajectory.
6.3. Basic settings of brush stroke
6.4. Form tab to change mesh (or section) inside brush
6.5. List of added parameters to brush (can be empty). Those parameters affects meshes during drawing and someteimes can make very different brushes with the same source mesh.
6.6. Overall settings which affects drawing with any brush preset (if possible)
