Ok tried my first meter sketch, so just scale down by 0.001 then export and we should be spot on in mm, just making sure I’ve done it right

its the dark blue part wrapped around the blade with the flexible tube coming off it

its for a Bosch mitre saw for dust extraction , about 80mm

I tweaked it a bit more, its not 100% , but I think it could work
bosch dust collector 8.skp

thanks for your time guys, instead of a radius I went with a chamfer, pulled the tube through then scaled the end up. This would be fine, all be it a lot neater , but the profile would work
bosch dust collector 7.dwg

"you" I mean SU, ;o)
ill give the meter to mm a try

bosch dust collector 6.dwg bosch dust collector 6.dxf

hope these help

evening all, I'm trying to put a radius around the tube on the outside and inside of the main body, any one got ideas?
the radius needs to go the extremes of the main body , so nothing at the top, 29 at the bottom and 8 to the side (model is scaled up)
its for a vacuum port , this is only a prototype, so its a bit rough
thanks Dean

Just a thought, why don’t you , I don’t know the word , reformat SU , so that instead of scaling up x 100, you make 1mm equal to 100mm

No , standard segments for a circle are 24, i prefer 48 so i change it and get the pop up
Don’t tell me you’ve never drawn over hidden geometry
