[jakubd]

Hello,

I need help with sweep along helical curve with variable pitch.

I need to get different angle from 12deg in the beggining to 15deg in the end of sweep.

Can anybody help me ?

Inventor doesn't have functionality that i know of like Pro Engineers variable section sweep.

i have already do this sweep along helical curve with variable pitch but my profile is the same on begining and end of curve,

i'm looking for solution to make sweep with transition from one profile to another,

in my profile only angle of arms in the trapezium profile need to be changed along sweep

[rdharvey]

well i would advise the loft feature with guide rails then. unless you have access to any other cad software.
