Altering alignments by each stage

[[An...]]

Is there a way to manually change the alignment of multiple changes? My prealignment gets me to close to where I need to be, but each part is off slightly. I can easily fix one stage via the "set Matrix" alignment, but this hurts all the other alignments. Is there a way to use the "Set Matrix" alignment on each stage individually? 

 

Thank you!!!

How specific is that prealignment mismatch?

I had no luck to fix prealignment on almost symmetric or rotary model.
Would simple bestfit help?
Like:

• do prealignment
• bestfit of selected part of a mesh based on prealignment
• next alignments based on bestfit.

Hi,

the alignment is applied to each stage. Maybe an alignment after the prealignment helps to refine it, like Martin proposed? 

It is possible to prepare an alignment during measurement, which helps for symmetric parts for examle: https://techguide.zeiss.com/en/zeiss-inspect-2026/article/how_to_create_initial_alignment_for_stage_projects.html

The original alignment ("as measured") would be defined as initial alignment in that case.

It would be possible to use a single element transformation (ZEISS Quality Tech Guide) per stage and use 'original alignment as initial alignment', but this is a manual process.

Hi Nanno!

Thanks for the fast reply. More information + pictures are below.

The highlighted area on the CAD is what's not aligning. Its a non continuous flange. I can create a section that only grabs this region (via creating a section from a cylinder), but am trying to figure out how to use this to get a point (or any other element) to translate from the nominal section to actual section. As I understand this, once I have that, I can use to align my parts.

Is there any way to create a point that is taken at the point furthest from another point or element? Like an inverse caliper? 

 

 

Thank you so much for you help!
