Unable to create sectional cut (Curve) using offset section

Hi everyone,

Would appreciate if anyone can shed some light on this.

I'm new to Creo 5.0. Trying to make a section cut in my part itself (Not drawing). 

1.View-> Section ->  Offset Section

2. I then select my sketch

3. And things work fine so long as my sketch consists of straight lines. If my sketch is an open semi-circle for example then Creo refuses to do the cut.

Am I missing something? 

Thank You

Sandy

Hi Martin, kdirth,

 

Please find attached pictures and the part of what I am referring to.  I am trying to do a sectional cut. 

View-> Section ->  Offset Section, from there I can choose a sketch. But it seems that the offset Section cannot display sectional cut from sketch that contains curve.

 

I know Catia can do that, and by extension Solidworks as well. I'm pretty sure Creo can do it, can it?

 

Thank you

Sandy

Hi,

unfortunately requested functionality is not implemented. Please read  https://www.ptc.com/en/support/article/CS252750 document. It contains following text:

Resolution

Possible workaround methods:
  1. Replace the arcs in the offset cross section sketch section with multiple smaller straight lines.
(OR)
  1. Create a Part Simplified representation defining work region that removes the material in the model using a cut feature. (View Manager > Simp Rep Tab > New > type in new rep name and hit return > Work Region > Choose desired feature to create cut geometry > complete feature creation.
  • Once the part simplified representation is created, use this to create desired view in drawings

Hi,

I guess semicircle entities are not allowed. Please attach a picture of your "cut".

Looking at the messages while trying to create the section in 4.0 I get the following message:

 

"Offset sections that include arcs or splines cannot be displayed as clipped in shaded mode."

 

You can use arcs and splines to create an offset section.  However, for whatever reason, you can not show the section in a shaded mode.  Works fine in wireframe.

There is always more to learn.
