Also, you can create a boundary interactively if you turn on the Smart Guides. Take the Rectangle tool and position the mouse cursor around the corner of the eventual bounding box that encompasses all objects. The Smart Guides will show "Intersect" label and two lines showing the intersecting points of the objects. This will guide you in finding the corner of the bounding box. Start drawing the rectangle from that corner and follow the same procedure to complete the rectangle at the opposite corner of the bounding box.
Hi, My explaination is not clear it seems. Real story is
For example i have a Bolt as a vector drawing, i have to give more thickness to its boundary i.e outside lines Bolt. The inner lines of the Bolts (inner threads also) are thin. By using few shortcuts how to give thickness to the outside lines of Bolt.
for clarity of explainatin i have mentioned a Bolt, but i have a big component, assembly, etc.
Thanks in advance.
