Is Recap the right tool for large point clouds?

Post by dlefebvre » Wed May 29, 2019 4:34 pm

Just like the subject says...Is Recap the right tool for large point clouds?
Clients keep asking for point cloud data in Recap format, but with scanners collecting more data all the time Recap can't seem to keep up. Client asked for their data to be split into 100m x 100m sections. This is fine, but it's also a dense plant area and I export this to PTX and have 130GB PTX files. It takes an immense amount of time to export this and then create the Recap data. Even unifying the cloud in Cyclone takes time.
Long story short...Is Recap built to handle data like this. Or should the end users be considering other products for massive clouds like this? I have all the right tools on my end so my Recap experience is very limited.

What is everyone else out there doing?

Thank you

+1 I also want to know this.

Recap seems to NOT be up to the task. Not enough Multi core optimization. We are working off a number of beastly computers and it’s taking a week to get files into recap and out to a unified.

Recap sucks. FOR US.

Soak that in.

It is awesome, however, for the end user. Functionality is built in to autodesk products. The easiest way currently (sorry Faro) to get data into a users hands in a USEFUL way is to give them recap files. They just drop it into their existing work base and use it.

I only use it to make rcp files once the cloud is in presentable form.

It sucks.

Use E57 “unified” for import and indexing into recap... That’s if you don’t need the photos

We use both scene and recap don’t have issues with Pointclouds around 150gb

I find a lot of people dish recap but it’s actually a very useful program if you use it correctly.... Been using for years now..... like all software learn the workflow

I do have photos...and I do need them. I suppose half my battle here is people assume this process only take a few minutes. 180gigs of PTX data is not going to import and index overnight...Or will it? Last one i tried was going for an entire weekend.

Don’t use PTX - Try E57 and if you need photos yes that will take some hours for that size....

I indexed a E57 last week of 180gb with photos and took around 3hrs

Export to rcs for modelling in Revit.

When exporting you need to optimise first.... “NEVER” crop and hide or you will have no hope of exporting

Hey folks-

As a scanner who is employed on the AEC/design side of the business, Recap is a must. RCP is the only format that Autodesk allows for importing Point Clouds into our design software. Additionally, most designers will request BOTH RCP formats with scan station photos, as well as unified unstructured data. This gives them both options for viewing pictures in Recap, and a unified cloud that is lighter in size for importing/linking into their design software of choice. Our personal choice is to use Webshare for viewing the scan stations, and a unified RCP for importing into Revit.

On the flip, if you can convince them to use Navisworks as their software for comparing Point Clouds to Design models, it can take .fls, .pts, .ptx, as well as RCP, RCS formats.

I'm fortunate enough to use CloudWorx and JetStream for our large point cloud data sets. This is why I ask the question, Is Recap the Right tool...or maybe its the only tool everyone is willing to spend money on. In most cases it doesn't cost anything (I don't think) if its included with the rest of the Autodesk software. The effort that goes into creating an LGS file compared to the Recap data is quite minimal. Never mind the load times etc. Everyone's work flow and requirements are different but it just seems like a hassle to me!
