Design

I like jwellary so i decide that making jwellary the casting material may be it is hydrostone or plaster of paris or rubber

I design the the mould in solid works actually first time i was confuse in positive and negative mould.Then i understand that if we want new mould i.e negative mould then put box at outside our object and fill the casting material in that mould and then put out from that positive mould

In this first i open the solid works then i draw the circle and extrude this part around 20mm

then i use the shell command and with 2mm border i cut the hollow part

after this i make use the style line and i make the earning

this is negative mould design
