Hello, I am trying to do a multiple copies of a single piece by mirroring it multiple times and at the beginning it works fine, so I did around 10-15 copies of the object I wanted but then the function just stops working… I am getting the following error: “Transform failed because sketch constraints could not be solved”, can someone tell me what’s wrong I am doing?

P.S. I tried to upload a screen recording but the system doesn’t allow upload for new customers ☹

Hey @Melir,  
My best guess without seeing your workspace is that the last copy would exceed the workspace boundaries which is 1km x 1km x 1km. If that’s not the case, please [open a support ticket](https://support.shapr3d.com/hc/en-us/requests/new) and we can investigate your issue.

Thank you for your quick response @Daniel_Horvath, unfortunately this is not my case. I will open a support ticket, so you can take a look.
