Being new to sheetmetal design, i was trying the formtools options.

initially creating a form tool, applying stopping faces and saving it in formtool location all went good.

Importing and creating the form shape also went good. Below image for reference .

the above was created using tool 2 and below one was created using tool 2 in the form tools folder.

when i am trying to keep tool 2 inside the tool 1, it is displaying errors.

"form tool overlapping with other form tool. Try repositioning it."

Tried possible ways that i know, but still unsuccessul.

please help me in this.....
