Online hosting of .DWG based surveys/plans

Have for a little while now been working on a map/plan (Not really a survey since I am more taking outline from abandonment plans and then from trip notes putting in collapses etc), due the the nature of the slate quarry, it has multiple overlapping veins so I needed to draw it within Autodesk as a .DWG file, so I can manage layers. With that I've been able to load in layers of historic plans, surface maps and surface photography.

I'd like to put this online since the mine isn't really accessible anymore and its the only way most people will be able to see one of the best slate quarries about.

My real question is, are there any online services that allow for interactive hosting of these sort of files? since I don't expect people who might want to look at it to have autodesk. Has anyone else done something similar and found a solution for displaying it online?
 
Does it have to be dwg? If you were to use geojson FeatureCollection for a complete survey, then an array of Features with the same layer propertyvalue for a specific floor, then there's a number of viewers around e.g. geojson.io. Github itself can nativelly display geoJson, so you could use that both as a repository and viewer.

We've got some GeoJson features coming to Buddlepit soon (a few development cycles away), but these will be features for given mine location rather than a general repository.
e.g. https://buddlepit.co.uk/mine-explorer/Database/Demo.html?id=1T3XOROf18Sm5oDk6rwOmg==

Am interested in any alternative suggestions.

Depending on what gets suggested on the viewer front, hosting of general dwg/dxf/geojson repositories might be something we can consider doing, e.g. it would be straightforward for us to maintain a repository of plans with some metadata, then display them in geojson.io for example.
 
Hmm, AutoCAD files aren't really a suitable web format.

Probably best way to go is to download QGIS (it's free) and try and get your head around that as a bit of software (well worth doing).

It's not something I've done to date, but you should be able to then export each Autocad layer as a separate DXF file, then import theose dxf's into a QGI project as a separate shape/point layer. You could then georeference them against UK National Grid, and then use the National Library of Scotland & Google Satellite maps as underlays.

At that point, QGIS should be able to spit out something that Berty (and Buddlepit) can digest and share.
 
I think I'd concur with EN.

We've used QGIS a fair bit. You can add any publically visible tile servers to it including Old Maps. I've had a look at the Georeferencer and it will accept vectors and points from a dwg file. You could then find 3 points in common on your dwg and base map, which you can then import into the main QGIS workspace as a georeferenced layer. You can then 'trace' extra layers on top (if needed) and export as geoJson.

Staring out, QGIS is a bit intimidating in terms of sheer number of options and data sources, but you can whittle out a workflow you are happy with in a couple of days.
