edge blend pattern 2

[saindip]

i am modelling a simple spur gear. it just seems impossible to pattern an edge blend at the root of the teeth. i have tried using feature and face pattern but all in vain. in case of former it shows 'edge blend cannot be patterned without its body parents' and 'the pattern cannot be applied. the selected faces might be an incomplete set for patterning.' for the latter. please help me otherwise i will have to select 40 similar edges.

I build once a gear as well. My process was to build one complete tooth section (including that section of the cylindrical part of the gear) and create a cylindrical pattern out of that to form the complete gear.
Following this procedure there were no issues with blends because the parents were also patterned.

i can understand that. but there should be a method to pattern out edge blends.

Hi saindip,

You have 2 options:

[ol 1]
[li]The suggestion above.[/li]
[li]Add the environment variable NX_ENABLE_BLEND_APPLY_ALL_INSTANCES=1 & restart NX/possibly log out/in for the variable to take effect. How this will work is that once you instance/pattern the tooth, you will then have an option in the Edge Blend dialog to Blend All Instances. Make sure you check that box (it will stay checked until you uncheck it and apply another Edge Blend later). Apply the blend to one edge or connected edges after you've instanced/patterned the tooth & the model should update accordingly such that all instanced/patterned edges get the Edge Blend applied to it.[/li]

Make sense? Hope this helps.

thanks Xwheelguy. but why put it in a separate environment variable?

 

[saindip]

Blend all Instances option is still not helping. everytime it shows 'edge blend cannot be patterned without its body parents'

In my opinion the solution I gave you is the most stable one.
If you still don't want to use that one then try the "Pattern Face" option from Synchronous modeling.
Or raise an enhancement request at Siemens GTAC.

NutAce's method is the best way to do this, but you can add the radii last if you create one tooth and array it. If you do this you can use the "Feature Intersection Edges" option as your selection rule for picking the edges. Example attached:
