oval to rectangular

[NateKennis3933]

i have a remodel job and all the old duct is oval.  i need to change it to rectangular.  the catch is i am just drawing the duct in with no fans and outlet sizes.  so i was just wondering if autocad mep can convert oval to rectangular without a flow rate.  thank you in advance

If you do not have any system information or equipment then you will need to resize the duct manually by selecting the oval ductwork and changing the shape to rectangular and then the size to the desired size.
