I was setting up my parameters that I am going to use in the default.svg and I have a problem.

All the measurements, the page and the grid, have been set up in inches. But the problem is that the measurements for the steps, which defines the amount of space when an object is nudged, are in Pixels. But pixels are totally useless to me because I was to align everything on the grid by nudging.

Is there a way to place nudge steps in inches, else how much pixels is an inch? Does it depend on the DPI of the file?

Yeah, and Inkscape pixels are not technically the same as screen pixels. Somehow they are relative, but I'm not sure relative to what?

....else how much pixels is an inch?

I've noticed that 100 pixels is fairly close approximation to an inch. But that's screen pixels....although 100 pixels per inch has worked well for me in Inkscape.

But if you're planning to nudge nodes to a grid, I'm wondering if snapping would be the better tool for you? You can set up snapping nodes to a grid using the Snap control bar, and there are other settings in Document Properties to adjust the strength of the snap.

Well, normally what I do is clip the first shape. Then duplicate the shape and use the nudge to place them.

In coreldraw, I used the translation dialog, but there does not seem to be something similar in Inkscape. Maybe the tiling dialog?

So your default file is going to have a repetitive pattern on it, right?
Then yes, Tiled Clones from the Edit menu would work. Although personally, it takes me so long to figure out what values to use, it's easier to just snap to the grid, lol! You know, I would snap a handful, then start duplicating those....have a handful of those, duplicate them, etc., etc., snapping the blocks of duplicated objects to the grid, as I go. Although if you do a lot of this, I suppose it would pay off to become familiar with the Tiled Clones dialog.

There is a Transform dialogue in Inkscape under Object menu, and you can choose the units

Yes I think that would be useful. There is no "apply to duplicate" button, but I can still ctrl-d and then apply.

Feature request has been filed (repeatedly ):
Bug #170293 in Inkscape: “Selectable units for steps”

(…), else how much pixels is an inch? Does it depend on the DPI of the file?

Inkscape's default DPI is 90 [1] -- i.e. Inkscape's pixel is 1/90 of an inch.

[1] This might change in future versions to 96dpi because the CSS specification which defines this default value has changed since the time the reference pixel was hard-coded into Inkscape's source.
