Within LeoCAD, you could use the snap function to align the orgine of parts to fixed positions on the grid. This very handy!
I would suggest to learn these short-cuts, which will increase building speed a lot.
Since LeoCAD is focused on Lego, the snap sizes are according Lego nomimal dinstances.
Lego brick sizes
This is a typical Lego brick, devided by these ‘unit’s:
Horizontal snapping (XY)
| Snap XY | None | 1/20 Stud | 1/4 Stud | 1 Flat | 1/2 Stud | 1 Stud | 2 Suds | 3 Studs | 4 Studs | 8 Studs |
|---|---|---|---|---|---|---|---|---|---|---|
| Distance [mm] | – | 1 | 5 | 8 | 10 | 20 | 40 | 60 | 80 | 160 |
| Short cut: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Vertical snapping (Z)
| Snap XY | None | 1/20 Stud | 1/4 Stud | 1 Flat | 1/2 Stud | 1 Stud | 1 Brick | 2 Bricks | 4 Bricks | 8 Bricks |
|---|---|---|---|---|---|---|---|---|---|---|
| Distance [mm] | – | 1 | 5 | 8 | 10 | 20 | 24 | 48 | 96 | 192 |
| Short cut: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Rotational snapping
| Rotation [degrees] | None | 1 | 5 | 15 | 22.5 | 30 | 45 | 60 | 90 | 180 |
|---|---|---|---|---|---|---|---|---|---|---|
| Short cut: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
An example
Currently it’s most handy to use for Mobaco library (v0.2):
– XY snapping: 1 Stud (short cut: Keyboard 5)
– Z snapping: 1/20 Stud (short cut: Keyboard 1)
– Rotational: depends, for walls use 90 degrees, roofs angles varies.
