Grid Offset

I am missing a possibility to enter an offset or zero point to the

grid I selected, With the different Pitches and the mix of inches and

metric I often have to switch and it would realy help if I could

switch the offset to.

Many of us miss that possibility. This wish is so old that it already

has a very long beard - yet it has not been recognized by CadSoft,

though this one should be really very easy to implement.

Regarding point 1, even if the grid had a selectable origin, I'm not so sure it would help in laying out components on a board,

because you would still need to perform a back-of-envelope calculation, to work out that origin.

Today, if I know I need to place a component at a specific point, I manually type the co-ords. I try to make my life easier by

ensuring that the component origin is at the correct location, to minimise/simplify the calculation.

Here is an example component (it is a connector), where when I designed the component pad layout, I placed the origin

to be the edge of the component (i.e. the end of the connector which I want to be on the edge of the PCB). The origin is shown

circled in yellow here.

Then, when I want to place it at an exact position on the PCB, it is really easy. I can just click on the part and type in the

exact co-ords (e.g. if my board is 100x100mm, then I can type (say) (0 50) and then I know it is exactly placed on the

edge of the board as desired, centered at the desired location.

There could be other use-cases for the selectable origin, but for placing components at a specified location, I have so far

found the manual co-ord method the easiest to be honest.

It is not so much a problem of placing parts, I agree manualy editing the position to a grid isn't a lot of work. The main pain is in routing, when you have mixed metric and mil parts or parts need to be on a specific location. Breaking out of the parts would be much faster if I could determine the origine of the grid. I am tired of calculating join points of mil and metric grids, or routing at small grids to have such join points in my grid.
