setting coordinate system

[jared.white]

Currently, the coordinate system is created by selecting a very small sample of points to set each axis.  We need more control over this.  If we are setting a coordinate system for a large building, the small area of points to set an axis does not result in a good coordinate system where the building is completely square.  

We should have an option to first set the z plane by selecting 3 points along the floor (or more points to get a best fit plane for the z)

then selecting 2 points along a wall (i.e one at each end of a long wall) that would represent the y axis

and then one point that would set x to 0

In metrology, this is refereed to as locking the 6 degrees of freedom.  (plane = 3, line = 2, point = 1)

In most cases, the z level plane should already be set because the scanner does this for you.  There is also no way to select the point on the floor and make it at a numerical elevation, currently it is forced to be 0.  We should be able to translate the origin to an imputed numerical origin so it can translate to a

Revit model. 

The current method recap provides is not very good, and is not a repeatable practice.

I have been able to manually locate a scan in AutoCAD and  use the DWG to locate in Navis, but this is a time consuming option. I have used control lines to help orient the scan of existing structures with fairly high accuracy, but I would like better. I am currently going to add a Level control line as the X&Y are not enough. and yes the tools for setting the axis's is unacceptable and we don't really want to purchase 3rd party software to increase the limited features.

Has anyone had success locating a Cloud in Revit the same way as i do in AutoCAD?

Hi @jared.white , @joe_truitt ,

I completely agree and here is a similar idea.

We are currently using the BLK360, it isn't being used every day. With that being said I was just been informed via email that AutoDesk will be/has discontinued supporting the Recap mobile application on the which is pretty much the easiest way to get the information into a desktop with out WiFi.  with that being said there are more robust point tools out there and recap seems to be limited and do not appear to be committed to scan data as some of the other providers. This disappoints me also, as we do have the suite which recap is included in. So if you are doing a large amount of point data, I recommend looking for more robust software that will have more tools to your liking. At this time I am looking at software should our usage increase as this information gathering is very robust for existing and ongoing conditions.  Hope you find this information useful.

That would be a great option. A functionality like the straighten tool for the horizon in lightroom would be great. That the user can select reference points which have a larger distance and accuracy with that. For example selecting two hall collumns from the start to the end of the building instead of choosing the coarse concrete surface of one column.
