I am working on a project where I get pdf files converted from cad drawings. These are they opened in acrobat and saved as an acrobat pdf document. These are then opened via LibreDraw and modified as needed to add network drops and or add cubicles as needed. The file is saved both as a LibreDraw file and exported as a pdf file. The group uses pdf files. OPenign the pdf files converted form cad drawings does not work at all. They have to be opened first using adobe acrobat and then saved as an adobe pdf file for me to be able to use LibreDraw.
When I go back to update the files as needed, some of the files have sections that are drastically shifted. Also some of the changes are no longer able to be changed as before. For example I create a network drop in a text filed to be: 54A/B. Later on this whole text can no longer be edited as one text field. It is shifted and each individual element ( 5 4 A / B) has to be edited and changed individually.
Why Is this happening? How can I prevent this from happening in the future? HOw can I fix these shifted files?
