Question

Corner chamfer workflow

Using Creo 7.0.5.0

 

I have a situation where I'm making a rectangular base plate for a table-stand. The plate has 2 mm chamfered edges and the 8 corners should be chamfered as well (see image below). However, this requires not less than 8 separate features which are tiresome to create.

 

Not only that - the dimensions are not remembered between each corner, they can't be mirrored or patterned either. Not even if an existing Corner Chamfer feature is copied and pasted to another corner the dimensions are kept (so what the point of copying it?). 

 

Anyone who has a simple solution to this?

Hi,

solution no.1

Create 1/8 of plate geometry and mirror it 3 times.

solution no.2

Use Copy/Paste Special to copy 1st Corner chamfer feature to other vertices. Then apply chamfer to edges.

    Hi!

     

    1. Well, yes, I see how this would work, but it seems mostly like a awkward workaround with a slight scent of "bad practice" around it.  😉

     

    2. I experimented a bit with this, and even though it requires manually selecting 3 edges for every new corner and ends up with just as many features as before, by choosing "Fully dependent with options to vary" all 8 corners can now be controlled from the "source feature". Closest thing to a set, I guess?

    You can apply a corner plane transition when making the chamfers.

      This is getting hot, but it still requires you to set every corner manually. Setting all transitions for the single Chamfer set at once would be a very reasonable functionality.

      That would be nice.  However, it may be difficult to implement with all of the different intersect transition types that may be in a feature.
