Yes please!

Can you please elaborate, why current grid option is not sufficient, or how it could be improved to fit all the needs?

Sorry, maybe I've missed something, but there is no zero plane grid? Is there a setting to enable it?

Im thinking a grid with 1m squares that is aligned to 000 x/y/z axis in ortho top bottom etc views. This way, a non georeferenced model can be visually aligned and scaled to the grid datum.

Hello PLAN8,

In the Model menu -> Show/Hide items section you can enable Show Grid option. And in Appearance Preferences tab you can specify the number of cells in the grid and its plane (XY, YZ, XZ).

Doh! thanks!

I don’t know how long that option has been there, I’ve been  missing it for about 10 years!! lol , but can I suggest putting it in “view” tab, rather than under “model/show/hide items/view grid”

It doesn’t seem very logical for it to be in the “model” menu as it’s not anything to do with the model, it is a view related item. Just a suggestion!

The obvious deficiency of the Grid feature is the limitation to sizes of whole metres only.

I'm guessing it's somehow limited to be a integer variable in the code? But could you just change it such that you're defining the size in mm?  So the default value of 10 (10m) would be 10,000 (10 thousand mm).
Working in mm would cater for almost all of us...  Unless you have customers using micrographs!     So to go the whole way, do it right for everyone, could we just enter the size in metres to any decimal places needed.  So 1.56m, or 0.00014m... Then the STEM Photogrammetry guys would be happy too! 

This would be very useful to for us Metashape Standard users, that don't have any referencing tools available.  When scaling an object, being able to just input its measured size of 672mm/0.672m as the grid size allows us to very quickly, and confidently align and scale it to the grid and set its scale... Instead of the current multistep palaver that's currently needed, and probably not known by most.  Being able to set the grid to whatever size we want, is just obviously what we'd want/need to do.

And the 2nd most obvious improvement to the 'Grid' feature, would be a 'Grid for us Underwater Photogrammetry divers.

Could we have a simulated water surface?
This would have a few variables that we set, to give us what would best suit the water conditions at the scanning site, or just to look good/correct.
The feature could start off being super simple, just a a flat, but tinted, semi-transparent surface... Or we could set a number of variables to make it hyper real:
* transparency %
* wave amplitude
* wave length
* swell amplitude
* swell length
* water tint (RGB value)
* turbidity value, if the transparency value doesn't do this well enough already
* in the future, animated waves!!!
* whatever else is needed to make the perfect waves 

Being able to set the transparency/turbidity and tint, would be amazingly useful for those scans of deeeep ojects, like deep wrecks, or just smaller coral heads...  This would give us back the view we get underwater, where we just can't see that far.   Almost everyone that's seen my scan of our Manta Point dive site, immediately say "Wow, the vis is amazing!", is it's like the water is super clear, clean.

Being able to visualise scale and its position in the real world is a massive problem for us UW Photogrammeters...  Drone scanners are scanning everyday objects, houses, cars, roads, trees, that we all know the sizes of, and they can just turn on a basemap, too...  Underwater, there's mostly nothing that's recognisable to scale off of, or anything that gives us a sense of depth of the object under the water.  A simulated water surface would do this!

Obviously, Blender can do all this... But i, and many others, have zero experience with it, and we just want to quickly see, understand, visualize, show others what our scans look like underwater.  Where the current Grid feature simply doesn't help enough.

This would make visualizing our shipwreck or our section of coral reef really easy, and it'd look super cool!
