Knife Project in 2.8 not working as expected.

Hi. I'm using Blender 2.8 for this modeling exercise. After carefully following Kent's great instruction I've had no success to effectively project the Boolean Box onto the Starburst. I select the Boolean Box first, then the Starburst in Obj mode, tab into Edit mode then deselect all,  all the edges of the Boolean Box are selected, then I select the Knife Project tool. My best result is the attached jpg image which only has a hand full of the verts projected.  I've tried several hours to work out this one problem. So, what am I doing wrong to get this anemic result?

Thanks for your support!

    theluthier Would be more familiar with the tutorial than I am, but one thing that could be tripping up this workflow is that 2.8 will bring both objects into edit mode! So it no longer knows what to project to or from. Instead, try using a Boolean modifier on the starburst object. 

    • To update you, I was successful using a Boolean modifier for the starburst as you suggested...(Never used that one before)... I selected the Starburst object and added a boolean modifier, the operation was intersect and the target was my Boolean helper, then applied the modifier. The process was successful but not clean, having to remove too many aberrant vertices and edges. I've attached the final result below.


      Thanks for the suggestion. I'm hopeful Kent Trammell can determine why I wasn't able to complete the starburst with Blender 2.8 .

    Yikes! Can you share your .blend file so I can troubleshoot it myself? The best way to do this is upload to dropbox, google drive, or similar file hosting service then copy and paste a download link.

    • Hi Jonathan and Kent. Thanks for both of your responses. For the time being, I've continued to move on to texture and shading using the completed MailBox source file provided. I will try using the boolean modifier (New experience) on my file to see how that will work. I've also attached a DropBox Link for my Blend file for your review. I'd appreciate your feed back regarding what the issue is or may be, whenever you have the time.  I suspect user error is most likely.

      Thanks again

    • To update you, I was successful using a Boolean modifier for the starburst as Jonathan Lampel suggested...(Never used one before)...See my reply to Jonathan Lampel.    However, I hope you're able to figure out why I wasn't able to complete the process in Blender 2.8.

      Thanks
