Alignment problem: Alignment By Coordinate Systems not working

[[Jo...]]

Greetings,

i start with a prealignment and construct everything i need for the alignment according to the technical drawing.

 

B1 and B2 are constructed on a section

 

Then i construct another line out of B turned around "Bezug C" for 37,059°

 

I construct a lokal coordinate system and align the axis according to the technical drawing.

 

I then make the local coordinate system the global coordinate system

 

and up with this

 

Does anyone have a idee what im doing wrong?

You have to setupin "Über Koordinatensysteme" both the same.

Upper is for nominal ( blue font ) and lower is for measured ( green font )

If i use the funktion like this ("on itself") it works, but i still have to use "use lokal coordinate sytem for display" to have visible effect on the workspace area 

I find it hard to always remember that what you see is not what you get.

Is there maybe something else to make the workspace coordinate system be in alignment with my coordinate system?

If you apply it on it self, then you see correct position of measured mesh and CAD model.

If you apply what you've tried at first ( i was able to perform it on free licence ), then you move only measured mesh, but CAD model will stay - so now you have problem with creating elements.

After i did "Target" as global and "Actual" as previously created system, then i was able to create plane from CAD, but actual plane can not be calculated.

If you are looking for changing nominals, then you have to change "Coordinate system" in your dimension flag settings

It is only a visual problem i think.

Like the CAD is build to show the xyz-axis differently then they are supposed to be according to the drawing.

Thanks for your help and have a nice weekend!

Hi,

it is important to remember that the CAD shall be imported in the "defined" evaluation coordinate system. If this is not the case you end up in trouble because the X/Y/Z aren't aligned by default in the wished coordinate system. Of course, you can "workaround" the visualization with the use of a view coordinate system but usually this is only necessary if you have multiple datums which must be evaluated in different coordinate systems and you want to create for each subset of datums nice report pages.

The alignment only aligns the measured data to the CAD. If you specify the alignment from an "arbitrary" actual coordinate system into the "Golbal coordinate system" you can transform your measured data far away from the original position of the CAD (which you have imported).  In this case it seems that the actual elements can't be calculated anymore after you have switched into this alignment (the error message hints it with "Nicht alle benötigten Elemente konnten berechnet werden").

Hope this helps?!

Hi Bernd,

das klingt als gäbe es die Möglichkeit ein CAD beim Import bezüglich des Koordinatensystems anzupassen oder deute ich das nur in deinen ersten Satz hinein?
