Merging PDFs
3D content pages can be appended and inserted into existing
PDF documents. The merge settings can be defined under the Conversion tab. There are two main ways of using this:
- Specify a Template PDF on the Input / Output tab, or
- Specify an exiting document as OUTPUT PDF, or in-place update.
To Define Merge Settings:
- Click Set Output from the toolbar menu or click on the Change button under the Input/Output Settings tab.
- Select the file to which you would like to save the converted PDF to.The converted PDF can be merged with an existing PDF file. Then on the Conversion tab:

- Select Merge 0: new or replace to create a new PDF or replace the existing PDF. Select this option only if you want a new PDF or overwrite an existing one.
- Select Merge 1: prepend to merge the PDF being created at the beginning of the existing PDF.
- Select Merge 2: append to merge the PDF being created to the end of the existing PDF.
- Select Merge 3: at page to merge the PDF being created at a particular page. Then specify the page number at which you want it to be merged in the Page Number field.
- Select Merge 4: replace existing annotation to insert a new 3D annotation into the existing document at the specified page by replacing the existing one with the specified number.
- Select Merge 5: at placeholder to insert a new 3D annotation into the existing document at the location specified by template place-holder layout parameters.
- Select other Conversion Settings, PDF 3D View Settings, Page Layout Settings,
Security Settings and click on the Convert button to begin the conversion process.
When specifying a template, normally a dialogue appears confirming a change the most appropriate merge mode. This can be modified as desired. The template 2D or 3D type is automatically scanned and determined. This allows the dialogue to either suggest setting Merge 3: at page, or Merge 4: replace existing annotation mode.
