Move existing project to reinserted point cloud.

Anonymous — Fri, 27 Jul 2018 16:33:13 GMT

Hi, I need some help. I inserted a point cloud center to center and continued to draw the project, now i have been informed that the point cloud should have been inserted via shared coordinates. Does anyone know a way to relocate the project so that it matches the new (correct) point cloud data?

Thanks.

Are you saying that it is currently in the correct position relative to your own project, but not shared? Or are you saying that it's in the wrong position relative to your and not shared? Bottom line: position it correctly in your project and set up Shared Coordinates.

It is currently in the correct position relative to where I imported the point cloud but, when shared, it does not line up correctly relative to where they have imported the point cloud.

I'm totally lost. Can you walk me through your workflow -- in order of operation?

Leave the pointcloud and your model where they are. Link in the model where they setup the shared coordinates and acquire. That's it.

....To move the project base point or survey point in a view, do one of the following:

.... or there is a couple of explanations on how to work with these points:

You would think, @ToanDN. But, I think I get what @Anonymous is saying now. He originally linked the Point Cloud directly into is Building Model (not correct), and probably using Center-to-Center or Origin-to-Origin. Now he being told to Link it in By Shared Coordinates. Consequently, the Point Cloud is landing in the Project relative to the Survey Point, which is displaced from the Project Base Point. Probably because he acquired coordinates from another Link or simply moved his Survey Point. Either way, leave the Point Cloud where it's at push these coordinates to other Links (e.g. don't Link in another project and Acquire its Coordinates). And if the Survey Point needs to be moved in this Project, make sure you UNCLIP it first. Frankly, the best approach would be to copy the current project, delete the Point Cloud from it. In the original Project, delete everything except the Point Cloud. Then Link the the copy (one without Point Cloud) into the Point Cloud Project, position it correctly and then Publish the Point Cloud coordinates to the Link. Basically, making the Point Cloud project like a Site Plan.

p.s. PIN the Point Cloud and Survey Point.

@aRcHiTeCt.JM: Did we miss something the first time you post this?

Actually, @aRcHiTeCt.JM, your re-post got me thinking.

@Anonymous: Did you rotate the Point Cloud Link to be orthogonal in your Project Views? If so, you're going to loose that orientation if you decide to reload the Point Cloud Link via Shared Coordinates. If you proceed this way (re-link PC via Shared Coordinates), make sure you Link it into a True North Plan View and measure precisely, the angle you rotate it to orthogonal. You're going to use this information for your Project Base Point's Angle to True North. Know of any good videos showing this, @aRcHiTeCt.JM?

This helped a lot @barthbradley. I copied and renamed the point cloud and imported it using shared coordinates. I was then able to mark similar points on both the original point cloud and the new before deleting both. I then used these markers to relocate the project. I then imported the point cloud again using shared coordinates and it lined up with new location of the project with only a few (mm) difference - well within project tolerances. Thanks to all who helped and sorry for my vague working at the beginning.
