Unwanted line snapping

[alll]

Hi,

This is my first post, long time hobby user of su.

Something really annoying. Lines get automatically joined even when i don't want it! (see video)

I make small pieces (1/10mm precision needed) for 3d printing.

Is there something to prevent this?

Thanks,
manu

Model 100x larger then scale down.

SketchUp doesn't like small dimensions.

?
Should i draw in meters (model units) or just enter big numbers without using decimal precision?
so 1 mm i draw 1000mm instead?
Strange, is there a valid explanation to this behavior? How does su handles this?
Thanks for your quick reply.

still no luck!

Do you have length snapping enabled in the model info->units setting?

Setting my units to meter and these precision, i found a work around ?.??...

Please attach your image directly.
This method does not work !

[alll]

like this?

Measure units are meter, i export in stl and model-units, import in 3d-slicing where units are milimeter...

With 100mm precision ???

If you uncheck that - any advance ?

[alll]

If i leave the precision at 0,0000 and snap at 0,1 and set the units to mm, I get the unwanted snapping!
Setting the units to meter, keeping 0,0000 and snap at 0,1 it "works"...

To summarize:

Precision:0.01
Snap:0.1

Draw 2 // lines L1=1.00”units” and L2=0.98”units” along the x-axis
Draw L3 from end of line L1 straight up along z-axis

With m (meter) units all is OK!
With mm (millimeter) units it screw it up!!!!!

So that is why I set units to meters, export to .obj, import into slicing software for 3D printing.

If somebody can explain this behavior? Because I still have other artifacts while merging different groups and “outer shell” them or do intersections, flat faces get “distorted” !!!
