@ ixam-maxi:
Welcome to the forum. Since this is an international forum
I will answer in German and English.
About your question:
In QElectro Tech there is the possibility to import image files
in the formats bmp,jpg,png and svg.
The existing PDF file must be converted into a graphic format for this.
This can be done by online converter or by software.
The following instructions will help you:
1. open the PDF in Microsoft Word, LibreOffice Draw or any PDF editor.
and mark and copy the desired part of the graphic. 2.
2. then open e.g. MS Paint and paste the copied graphic and save it in the desired format.
3. import the graphic into QElectroTech with Paste Image.
4. if the image is not the right size, you can adjust it with the function Right Click > Edit Image. 5.
5. with a right click on the empty slide the columns and rows can be adjusted
with the command Slide Properties.
6.Now you can draw over the inserted graphic and export the created document as DXF, PDF or SVG.
for exchange with other programs.
