HOW CAN I INCREASE R55 TO R75 ?


I AM NOT ABLE TO CREATE A TRANSITION

How do you want to deal with the indicated transition?

IS IT POSSIBLE WITH A PATCH SURFACE?

... is how I'd go about it. It amounts to copying the relevant surfaces (after deleting Round29 & 30), extending, filleting, merging and solidifying. Note layer solid_goemetry which allows hiding the solid body while you work the surfaces.

(This is an interesting fillet problem and I intend to play with is a bit more when I have some time to see if there's a way to solve the R75 (after deleteing Round29) using transition options.)

you can try to walk it up also, it may take

Hi everybody


I enjoy a lot comming in this forum where I find a lot ofskill users andbrillant tips.


Concerning that situation I tried instead of going into complicated maneuvers to make the rad before chamfering. Remove the chamfer, make the 75 rad and make chamfer. It worked correctly becaude the rad does not extend beyond the part in thise case. In other case I would probably gone in the direction of jeff4136.or would probably try to manage with transitions.

It works


By manipulating the trtansitions it works fine.


Start rounding, remove(delete) 2 existing transitions(you must be in transition mode on the dashboard), replaceboth by one new transition by picking/selecting both edgeswithCTRL+click.


Rounding is a very tricky aspect of modeling whatever the software.

...one new transition by picking/selecting both edges

Hi everybody


When i have deleted transitions how can i made a new one?


Iselect the two edge with crtl end ....

 

[james.lynch]

can you not just reoder the model tree (move round 30 above round 29 and chamfer 3)? works fine for me..

Absolutly james.lynch


That is the easiest way.


But it does not work when come time for larger radius for ex. R80, I experimented andcame to conclusion that redefining transition was the solution.


Thanks

Minrob, after selecting the edges RMB, Make Transition. You can also RMB again and investigate the different types of transitions that may be available (will depend on existing geometry). You can also do it all via the "slide up" and list boxes on the dash panel.

James, you can indeed just re-order features (in this particular situation) but you'd want to replace the chamfer with a revolved cut to preserve what I imagine to be the intent. The chamfer following the R75 no longer represents a conic face.

Why not simply revolve a cut around the same axis, and remove material?
