To my knowledge this remains a difficult issue. It is mostly the land of user hostile software, and as you have seen, major data conversion issues can be a stumbling block. Also, unique for most geologic software, this is the realm of computational needs that challenge anything that wouldn't have been called a supercomputer just a few years ago. Using Move for this application is an example. I've used it for this application but their visualization engine is such that I have only been able to use it on super high end machines with super graphics cards. (aside here--Move might be out of the picture for many of us now anyway thanks to policies of the american lawyers and accounts at the company that acquired midland valley, but that is a different subject)
anyway, all that aside, there are some solutions. Andreaa Bistacchi just gave one suggestion. Here are a some other options, depending on your application:
1) Have you looked at VRGS? I think it has all the capabilities you suggest, although I've had some problems with stability of the software--make sure you have the right hardware.
2) you mention cloud compare, it does have some of the features you need. You can digitize lines on the point cloud or tin in CC, then export those data to another program for modeling surfaces. (this runs into the dreaded data format issues, but CC has a lot of file output options)
3) maptek's i-site studio (it has a new name, can't remember what it is) has all the features of cloud compare and lots of other features, but doesn't have the geo model building features, so like CC you have to start a project there, then move to another platform. clunky, but the visualization engine in i-site is superb; but it is also a commercial software package where you may have to jump through a lot of legal hoops to use the software. Maptek's other software (vulcan) has, I think, surface modeling capabilities, but I never had the energy to learn the software as I am told it is the ultimate user hostile software--very feature laden with a lot of bells and whistles uniquely tuned to the mining industry. maybe someone out there has experience on vulcan and can clarify? again though, still a commercial package that is hard to get.
4) another commercial package is leapfrog geo, but last I checked it has zero capabilities on displaying these kind of data; but it is user friendly for making 3D geologic models if you can get thee basic info elsewhere, and bring it to leapfrog. (again, extra steps, extra software, and the sofftwarre requires a license)
so good luck. I think you have hit on the single biggest reason this technology has not taken off more in geology--complicated software not quite tuned to the job many of us what to do.

Subject: Interface between Digital Outcrop Model (DOM) and 3D Structural Model
Dear Geotectonics Community,
in the context of our outcrop analogue studies revealing the deep
geothermal potential of Variscan metasediments and metavolcanics (Harz
Mountains, EU-Project MEET) as well as our upcoming 4th workshop on "3D
surveying methods in Geosciences" in Goettingen, we came across some
long-running questions:
Are there 3D structural modelling software packages or other solutions,
which cover the gap between digital outcrop models (DOMs/VOMs) - point
clouds, meshes, textured meshes - and "traditional" structural 3D models
sufficiently? This question mainly focuses on import data formats,
number of points or triangles, import of colours/textures and satisfying
rendering (e.g. MOVE nor GOCAD do not fulfil these needs, yet).
Furthermore, does someone know open-source/open-access or cost-effective
solutions, which are an affordable option for students (beside
Cloud-Compare)?
Thank you!
Kind regards,
Bianca Wagner
