Models change rapidly at various stages of the project, and it can be useful to review model status between different revisions of the models. What changed? Why?
There are a number of Model Compare tools out there, Navisworks has one built-in and there are addins for Revit. But what if you just want a quick visual check?
Here is one method using Revizto…
Using Two Instances of Revizto and the Issue Tracker to Compare Models
Open two instances of Revizto and put them side by side on your screen (large monitor will help)
On one of the instances, go to Project -> Revisions and open a previous version of your model
You can now navigate between two different versions in these two instances
The issue tracker data is always up to date, so you can use the Issue Tracker to co-locate yourself in each file and check the differences. Just click on the same issue in the Issue Tracker, and then click on 3D to visually compare the models. Obviously, you can also enter data and snapshots into the Issue Tracker as per usual, perhaps to comment on why a particular model changed between versions.
Essentially, this idea was to launch two instances of Revizto and use the Camera Share tool to navigate the same model between them. It was a bit more involved, and it requires you to have access to two different login accounts for Revizto, and two different login accounts for the current machine, and Revizto is installed ‘For Everybody’.
(needless to say that you should be careful to protect the password above)
Open Revizto normally and login
Run this CMD file, and in the new instance of Revizto you can login to a different Revizto account
Open the same Revizto project in each
You can now use the Camera Share tool to ‘drive’ both instances simultaneously. Pretty cool!
In one of the instances, open a previous Revision of the model
*This is where the idea fell down, as Camera Share no longer offered to share camera between two different versions of the model :)* Evidently, it won’t let you navigate non-similar models at the same time.
I re-tooled the steps above from my previous post about logging into multiple Autodesk logins at the same time:
OwnCloud is a free file sharing and syncing software, and for the most part it works ok. I don’t think it really compares with a full featured, appliance based enterprise solution… but, its free. You may find it useful for sharing folders on a BIM project, but it can be prickly at times.
If you are using it and want to run multiple instances, perhaps to work with multiple folder structures or different OwnCloud permission accounts, you can do it this way (tested on Windows 7 and 10):
Make a new local PC user account to run the instance. In Windows 10 this is by: “Add, edit or remove other users” settings option from Start menu, then “I don’t have this person’s sign-in information”, then “Add a user without a Microsoft account”
In Windows 7 it was the more traditional user management, which you can access from Computer Management – Local Users and Groups – Users – rightclick “New User”
Set a password for this new user and give them Admin permissions (consider security of this in your environment…) You can set a password using Control Panel: User AccountsManage AccountsChange an AccountCreate Password
Make a CMD with contents like this: psexec -u YourNewOwncloudUser -p YourNewOwncloudUserPassword -d -i “C:Program Files (x86)ownCloudowncloud.exe” This cmd will launch a new instance of OwnCloud executable under a different username using psexec…
Go to %APPDATA%MicrosoftWindowsStart MenuProgramsStartup in Windows Explorer
Make a shortcut to the CMD from step 4
Double click the shortcut now to test it
First run will give you the setup stages for OwnCloud (Server, Username, Password). You don’t ever need to use that user account you made for anything else, it is just there as a separate identity for the OwnCloud process
Before adding folders to sync, you should add Read/Write permissions to a Folder on your pc to that new user you created in step 2, something like this:
In Task Manager, it will look something like this:
Now, you have a new instance of OwnCloud, running at startup and syncing with different OwnCloud credentials to a folder on your PC.
