Techpacks can only be edited by the owner of the techpack. Collaborators, such as factories, only have 4 available functions:
1. Print PDF: Click on the "PREVIEW PDF". Directly download or send a PDF with any techpack shared. All versions of a techpack will be recorded automatically. Go to Techpack Versions article to learn more.
2. Enlarge Image: Click on any card, and inside will appear as gray contents with *⃠ , because the edit function is disabled in shared techpack (see image below).
3. Comment: After taking a close look to the style, the next step is to make comment respectively. The comment box is located at the bottom of the page. Inside the box, you can leave a message for your partners, by inputting "@" and their name. Again, don't forget to press "Enter" after texting. You can now discuss any issue right inside the card. You can explore the Comment article to learn more.
4. Share Files: you can also attach a file in any format for a better visual explanation. Click on the paper clip icon in the comment box to choose the file from your computer (see image below).
