Does this image work?

@graham-park I knew this, but I hoped for an solution.. Too bad.
If I convert it to text and the revision changes it does not change in the document..

Yesss.. that’s the one I had in mind. Thanks @kimmi-patterson

So problem 2 is solved..

Now I need a solution for problem 1 :)

Thanks @graham-park

final code:
(?=implant[|\[||s|\:\.\,|\{])i

This code will cover the most. And it will do the job just fine.
But I want to be sure to cover all possibilities. And if there is one possibility that could happen it is (implant) or ‘implant’ between

So i added “|’|\(|\)

(?=implant[|\[“|’\(|\)||s|\:\.\,|\{])i

Thanks for the smaller code, but it doesn’t do the job

For example: 20x20x20cm and 10x30mm
changes into 20 x20 x20 cm and 10 x30 mm

And I changed the replace code by $1~s$2 because I don’t want to have regular spaces. I used non-breaking spaces

I’ve found how to find mm or cm

Search:
(\d+)(x)(\d+)(x)(\d+).?(mm|cm)

Replace by:
$1~4$2~4$3~4$4~4$5~6$6

Wow! That works perfectly…. Thank you very much.

Btw is it possible to have a crash course in GREP given by you? ;)

Is it possible to get in contact with you via web? I also come from the Netherlands.

Does this works?
