Mold Tool - Paste Envelope Button
The Paste Envelope button on the Mold Tool Infobar takes a shape from the clipboard and pastes it as an envelope over the selection. For this operation to succeed there must be a four-sided shape on the clipboard. An error will be reported if the shape is unsuitable to be pasted as an envelope. Once pasted, you can edit the envelope as required with this tool or with the Selector Tool.
Note
The shape on the clipboard must have four sides. The sides may be curved or straight.
