how to make inkscape precise

Dear all,
how can I make precise drawings in Inkscape?
I have done several drawings in Inkscape, this tool really is great, but I am not able to make a precise drawing with it! The grid is activated, but still the resulting lines are not precise on the grid. This error becomes strongest if I export the drawing to a PDF. If I then view the drawing with acrobat at different zoom factors, then I see clearly that all the lines have small shifts against each other.
This is really devastating. Is there a trick to make Inkscape precise??
Please let me know
Best regards

By default Inkscape uses the "visual" bounding box of objects to snap them. I.e. a simple line can snap to either of it's borders (and hence shift a bit from the grid). To make Inkscape precise you can switch to "geometric" bounding box snapping (Inkscape preferences > Tools > Selector > Bounding box to use). This way only nodes will snap and the line will be perfectly on grid. There is however a caveat with this setting currently: vertical or horizontal lines do not show any selection mark and can't be moved with the selector tool (their nodes can be moved with the node tool and they can be moved with arrow keys however).
To everyone: - is this setting really at the best location? It seems a little hard to find there. - is there someone working on the previously mentioned bug currently? It seems pretty important as it makes the geometric mode very hard to use

Dear JiHO,
thank you for your suggestion. The idea sounds like a real solution. I really like to have have all my lines snapping with there nodes to the grid. All the time, will all operations.
Now, the problem is, I can not find that suggested options!
Here my details: Inkskape 0.45 (Linux)
File->Inkspape Preferences... This gives me a dialog window in this window I select the option: Tools->Selector in this window I have options like: -> Show selection cue -> When transforming show (Objets | Box outline) -> Per-object selection cue (None | Mark | Box) -> default scal origin (Opposite bonding box edge | Farthest opposite node)
Well, that's it! There is no option "Bonding box to use".
Please advice.
Best regards

Oooops sorry, the option in only available in the development versions of Inkscape (the more recent versions). You could probably get one for Linux quit easily though I don't really know how and where.
Anyway, in 0.45, you have the options directly in the document snapping properties: Document preferences > Snap. There select: Snap nodes to grid/guides and deselect Snap bounding boxes to grid/guides. Then select "Always snap" in both. Plus, you may want to activate some object snapping properties, keeping only nodes options to still be precise.
I hope this helps.

Dear JiHO,
thank you very much for this information! I'll test it with my next drawings.

Dear Lucas,
Ctrl does not help.
The off grid issue, especially with clones, is a real problem for me. Beside this, I am happy with Inkscape.
Best regards
