Geometry Creation Difficulty

Hi,

I would like to know if there is any approach generate this geometry just redefining a feature curve end getting this geometry (see OK.png) The idea is adjusting this sketch curve the solid geometry to be update, but I was not able to achieve it just changing the feature curve.

I'm able to generate this geometry (see NOT OK.png), but I don't need the round ends. I was thinking if there is any flexible modeling feature or any approach to remove the round ends.

Thx,

It's such a vague description without context. the possibilities are endless.

Probably yes. A clarification on design intent would be helpful as @StephenW mentioned.

Here is a Creo 7 part with two methods used to create the geometry. The model is saved in insert mode, resume the suppressed features to see the second method. You can modify the curve and the geometry will regenerate but there are limitations on this and that is where the design intent becomes important.

Hi,

thank you for investigation and I attaches also a model with more details:

- Please redefine the feature CV_RUN_LEVEL1_EDIT_DEFINITION with more or less segments and the geometry will be updated

- this curve is the only feature that need to be updated with more or less segments and solid need to be update without failures

- this is the only approach that I was able to find, but the idea is the number of segments will be added or deleted he solid model not to fail.

- The problem is the cylinder ends I would like to be rectangles. I can apply extra cut geometry or UDF or Flexible Feature but I'm we try in future to be automatically updated.

It appears you want to automate the creation of a runner tree structure for a mold design. I made some assumptions about symmetry for a balanced multi cavity layout and broke it down into two sketched curves to get this result. This is automated by editing the number of branches needed on the tree rather than the driving sketch. Would this solve your issue?

Creo 7 model for reference posted.
