Running program "upside down"

[[Er...]]

I am trying to remember how I did this. See attached.
Blocked edges are on Z+, the "top."
The clearance plane for features are Z- because the CAD is upside down.

I have tried the Special-keep original CAD alignment.
I tried Standard alignment, RPS, and 3D best fit.

This should be a simple task.
I've never understood where this setting is hidden.
Or on other programs why sometimes Calypso refuses to "flip" the blocked edges unless I "flip" the CAD.

This? Go to resources, scroll all the way to the bottom and select "set base alignment to zero" to fix it and then fix what ever is causing it in the alignment.

[[Er...]]

For clarification, the other part program ran fine with Z+ blocked. Feature clearance planes were set to Z-.
I just can't remember how to replicate this.

I am trying to recreate the same condition in a new program. I WANT Z+ blocked.

The blocked edges cube orientation is displayed relative to your base alignment(the trihedron in the bottom left will always be +Z up, +X right), with the 4 default edges always being whichever 4 are towards the granite (whatever the alignment, you generally don't want the CMM to try to move from one side of the part to another by travelling on the granite side, because the column would have to pass through the part). What this image is saying is that, relative to the cmm, your base alignment is selected with +Z down. The only way to change this would be to change either your base alignment orientation, or your CAD orientation, such that a different axis is "towards the granite". In your case it seems you want the +Z towards the granite.

Yeah, sorry I misinterpreted your post. Had a little bit of time before all hell broke loose this morning and made a quick reply 🙄
Looks like Kevin has you on the right track.

I could not get Calypso to make the BA the same as the previous program.
I just used RPS after "CAD Model transformation" then set up an Alignment so I could report the points, etc. to the CAD coordinates. Extra steps, more to double-check.

I had hoped someone could tell me how I did it before 🤣

The only thing I can think of is adjusting the spatial or planar orientation direction(whichever controls your Z)

Kevin,

No joy.
What language is the base system file in the basesystems folder? Opened with Notepad nothing is obvious to me.

As many tutorials and hint says - first rotate CAD model to correct position ( basically rotating to have correct +Z axis ) then make base alignment.
Otherwise you won't have that flipped circled edges at bottom.

Unfortunately for me I WANT the Z+ blocked at the top. But because I want it Calypso is "fixing" it this time. 🤣
The only reason I want to is so the customer can compare a previous suppliers data.

I just started writing another program that the CAD is "upside down" and not "square" to the coordinate system. I tried 3 times to get Calypso to "block the top" and gave up. I translated and rotated the CAD per normal.
Using RPS alignment with rotations and offset I was able to set up the vehicle coordinates. Now the customer can compare my data to a previous supplier.
