I'm so sorry, but it's non professional and useless. You must to use bevel for this kind of design for taper bit. Otherwise you lose all small details. it's much easy to do simple offset if you like to check milling areas.
sorry but you don't know what your talking about!...you cannot offset everything to make space for your tool bit.and not bevel either ....if there is no room for your bit to mill the details in your design you must use point editing or some other way to 'open' up the space for your bit!... see these pics before and after... on the after picture I know the bit will be able to mill everything in those areas ..on the before it will not mill the fine detail because the bit will not fit in those areas..think about it!... or better yet try milling one to find out before you say things are useless and unprofessional.
here is the scroll adjusted for the bit milling down .75mm ..after adjustments all areas will be milled ..dimitri in case you didn't know the tool path will not let the bit cut areas it cannot get into..example if you have a 3mm bit you cannot mill a 2mm slot the tool path will not let you!.it's not the same as growing if I were to grow it I wouldn't worry about it.... I would worry about the widths and thicknesses...
one more time in case you didn't get it here are some renders of the milled piece after the tool path was cut....on the unfixed scroll look at the areas the tool cannot access or mill because the space is too small, on the fixed scroll all areas are cut!...that's what you can use the gauge tool for..so you don't have uncut areas!
