Exporting PDF does not show all objects

Hi, I am trying to export a pdf of my final drawing, however when I open the pdf it does not show some of the objects…

Anyone who can help me with this?

Here is my code:

The final pdf should look like this:

but I am getting this:

image864×884 17.7 KB

Is there anyone who can help me with this?

Hello @Ties2901,

PDF Export Library Reference:

Find this section in the above reference and implement that:

Many Frames Into One File (With Screen Display)

I was able to capture many frames to a PDF.

Voila!

Hi GLV;

I have implemented the example from the link you have send me, but unfortunately I still do not get the entire flower ;(

Would you be able to check if i have written it correctly?

Thanks!

Sorry I saw I did not place the begin record in the setup, but now I have done this it gives me the following error:

Hello @Ties2901,

You need to be methodical, meticulous and scrutinize your code and the example code.

  • Remove all code related to PDF in original code or comment it out.
  • Add code related to PDF for multiple frames.

Looks like you have code leftover from your first effort.

I will leave you to find it… this is your journey and it is worth the effort in the long run.

Thank me later.

:)
