I totally agree with the slowness and uselessness!
I have been using Recap now for a few years and find that it has never really been improved in terms of performance. I tend to use the Faro products to export to RCP files, but I am finding the FARO SCENE now has so many new tools that I am spending more and more time in this application giving the end user what they need rather than using Recap.
I am so disappointed that Autodesk do not see that this application could be so much more that it is now. Do they not understand that this slowness and poor performance is driving users to other applications. I feel that this product will soon be unsupported and users will be left with a tool that does not work in a design workflow that Autodesk say is seamless.
I work with laser scans frequently (between 20-40 scans max) I have utilised all the tips and tricks with regions, exporting rcs files etc..... also my laptop has been upgraded a few times and still the application is sluggish and poor.
They removed a very good beta tool (mesh object) that I assuming was because no one was using it, this could have been down to the fact that Recap is suffering with performance issues.
Unless Autodesk see this product is being used frequent they will not fix these issues, I urge users to take the time to tell Autodesk how they use this product and what can be done to fix this or it will soon become another SHOWCASE!
