Thank you Dave R,
for your help and advice! I tried to fix it by myself and idea to make them all to components was great.

Hello Dave R,
I could compress the object based on your input and deleted the circuit board and posted it again.
All object should align to the base plate.
Before I am playing with the mentioned plugins (thank you Pilou!) maybe you just give me some ideas then I can try it by myself.

tilted object in space

Thank you for help

Hello,
I am lost how I can align several objects. All my objects sitting somewhere tilted in the space but I cannot align them to one reference axis and stick them all together. In my example I want to put a hemisphere on top of a cylinder, placing them on a base plate and finally having a peg added in the center. It's like a mushroom
Thank you for your help and advice.
Note: Unfortunately the skp file is >2 MB and therefore I couldn't upload it due to file size restriction. I added the print as pdf
