<p><span style="font-size: 12pt;">Good afternoon,</span></p>
<p><span style="font-size: 12pt;">I'd like to ask how to open the "Boundary" window in XCrySden version 1.5.60. The AI help suggests that XCrySden has a "Boundary" button, which is usually located on the right side of the control panel. However, I couldn't find this button anywhere.</span></p>
<p style="text-align: justify;"><span style="font-size: 12pt;"> I need this button to visualize all 18 diamond atoms in a complete cell as part of a complex structure, along with the graphene atoms, if I specify only 8 internal carbon atoms in the ATOMIC_POSITION panel. Another method, via the "Modify" and "Number of units drawn" panels, suggested by the AI help, doesn't open the "Display all atoms in the unit cell" option, and therefore, the 10 boundary carbon atoms that make up the 18-atom diamond cube aren't added.</span></p>
<br />
<p><span style="font-size: 12pt;">Could you advise me on a possible solution to this problem?</span></p>
<br />
<p><span style="font-size: 12pt;">Sincerely,</span></p>
