Hey there, have you ever experienced the frustration of creating groups in your 3D modeling software, only to find out they're not showing up in the 3D view? Let's troubleshoot this together! First, make sure your groups are not accidentally hidden or set to be invisible in the visibility settings. Check the 'Display' or 'Visibility' options to ensure your groups are set to be seen in the 3D view. If the visibility settings seem correct, it could be a glitch in the software. Try restarting the program or updating to the latest version to see if that resolves the issue. Additionally, check if the groups are positioned correctly in the 3D space. Sometimes, groups may appear far away from the center of the view or outside the boundaries of the scene, making them seem invisible. Lastly, if you're working with imported models, they may have their own visibility settings that override your group settings. Make sure to adjust the visibility of the imported models as well. Hopefully, these troubleshooting tips help you uncover why your groups are not appearing in 3D view and get them showing up as intended. Keep creating and exploring in 3D!
