Question

CREO 10 SWEPT BLEND ON A CURVED SURFACE

CREO 10

 

CAN YOU COMPLETE A SWEPT BLEND (OR ANOTHER WAY IF THIS IS NOT THE CORRECT FEATURE) FROM A PLANER SKETCH TO A CURVED SKETCH, OR PROJECTED SKETCH ON A CURVED SURFACE?

 

HIGHLIGHTED IS THE PROJECTED SKETCH ON THE LARGE BODY, THE CURSER (SMALL RED LINE) IS THE OUTSIDE SKETCH OF THE DUCT.  FOR THE DUCT, I MADE THE BODY WITH A SWEPT BLEND.  HOWEVER, I NEED TO ADD AN OUTSIDE THICKNESS LAYER WHICH WILL STOP AND CONFORM TO THE OUTTER SURFACE PROFILE OF THE LARGE BODY.  SO BASICALLY, I NEED TO CREATE A LOCATION STOP/SUPPORT FOR THE DUCT (THIS IS REASON I NEED TO ADD EXTERIOR THICKNESS TO THE DUCT), THIS WILL ALLOW ME TO PRINT THIS SEPERATE (IN A DIFFERENT COLOR) AND ASSEMBLE IT TO THE LARGE BODY.  IT IS CRUCIAL FOR ITS LOCATION AFTER ASSEMBLY.

 

I CANNOT PERFORM ANOTHER SWEPT BLEND FOR THE EXTERIOR TO CREATE THE THICKNESS BECAUSE THE SWEEP WILL NOT STOP AT THE CURVED SURFACE.  WHAT ELSE CAN I TRY??

 

ANY HELP IS APPRECIATED.

Are you able to offset the swept surface to the desired thickness? If so then you can offset the swept blend and then trim/merge the proximal and distal ends with surfaces to get a closed quilt that in theory would solidify. Basically, overbuild the geometry with surfaces and trim/merge to get the desired result.

 

You could also get this done with multibody solids and Boolean operations.

 

As with most geometry in Creo there are multiple solutions. Design intent should be a consideration in addition to accurate geometry.

HERE'S ANOTHER PICTURE, THE DUCT GOES THROUGH THE BODY A SHORT DISTANCE TO THE INSIDE, THIS NEEDS TO STAY AT THE OUTER DIMENSION TO FIT THROUGH THE OPENING.  WHAT I NEED IS TO THICKEN THE DUCT ON THE OUTSIDE OF THE LARGE BODY.  I NEED THE INCREASED THICKNESS OF THE DUCT TO STOP AT THE CURVED SURFACE OF THE ABUTMENT JOINT AT THE LARGE BODY.  I'VE TRIED RE-SWEEPING THE PROFILE AS A SURFACE AND THEN TRIMMING AND THICKENING BUT I JUST CAN'T GET TO WORK.

I CAN GO BACK AND TRY THE SWEEP AS A SOLID THEN SHELL.  I'VE TAKEN ALL THE CREO CLASSES, AND HAVE BEEN USING CREO FOR SEVERAL MONTHS, BUT I AM STILL SEMI-SKILLED IN USAGE.  I AM NOT SURE WHAT YOU'RE REFERENCING FOR "PROXIMAL AND DISTAL FACE SURFACES".  I DO NOT RECALL THIS IN THE CLASSES.  WOULD YOU PLEASE EXPAND ON THIS.  THE PLANAR SKETCH IS AT A SLIGHT ANGLE/PITCH COMPARED TO THE LARGE BODY, SO WHEN THE SWEEP COMPLETES IT CREATES A SMALLER ARC ON ONE END OF THE SWEEP

If I interpret the pictures correctly, then this is what you are targeting. I have enclosed a Creo 9 model using surface modeling and multibody get this geometry as seen below. This is to demonstrate a modeling approach that is feasible.

THANK YOU FOR ALL YOUR HELP.  THIS GIVES ME AN ALTERNATIVE FOR ANOTHER MODIFICATION.  LET ME EXPLAIN, SORRY FOR NOT INCLUDING THIS (IF I FORGOT), THE BASE BODY IS AN EXTRUDED CUBE, THEN SHELLED.  I HAD TROUBLE THINKING ABOUT THE BEST WAY TO GET THE OVERALL SHAPE I WANTED AND APPROACH FOR THE BOX BODY, SO I EXTRUDED A CUBE, THEN CUT THE EXTERIOR TOP SHAPE AND SIDE CUTOUT, EDGE ROUNDS...THEN SHELL.  THIS I BELIEVE (NOW) IS NOT THE BEST DESIGN APPROACH FOR WHAT I AM AFTER FOR FINISHED PRODUCT...AFTER THE FACT WITH ALL THE FITS I'VE HAD.  AS YOU DID, I SHOULD'VE USED SURFACES TO CREATE THE BOX, THEN THICKEN...I PROBABLY WOULDN'T HAVE THE PROBLEMS THAT I'VE HAD.  BUT...IT'S WHAT I HAVE RIGHT NOW, I WILL ATTEMPT SURFACES FOR A MODIFICATION WHEN AVAILABLE 🙂
