Design Chalange

Guru's,

 

I have a special task to advise with you.

 

while designing a RF box ( electronics ) i need to create many wall for the sake of enable separation areas between antennas.

 

The easiest way to achieve would be to simply create a sketch with many lines ( not intersecting either creating close loop ) and simply use extrude thin in order to achieve.

 

This can be done quite easily in SW however i can't manage to find thy way achieving the same in Creo.

 

Doing it manually, one by one, is always an option however would require 50 separate features. i would like to avoid that.

Tried also to facilitate Rib feature - again no luck.

 

Any suggestion ?

Based on your picture I would define a User Defined Feature to create a reference rib collection of features. You can then place this UDF using your single sketch of the rib positions and orientations. Each line in the sketch would anchor the placement of the UDF.

 

It looks like you could create a pattern table that would specify the location of each rib and a clocking angle to control orientation. Using a point and csys as the pattern leader would define the position and orientation. You can then use a reference pattern to place a rib at each instance of this pattern.

Patterning the walls would be simple. I'm sure there are other circumstances that make patterning a bad choice but from your description, it's all I can quickly come up with.

Steve,

pattern isn't an option as there are no pattern rules that can match.

It is not clear from your post if you tried to use trajectory ribs. I have used them to do exactly what you are describing since they were added to Creo. With a combination of trajectory ribs and patterns you should be able to make short work of this. Is there something about the core side of your enclosure that is  preventing you from using the trajectory rib?

Hi,

the issue with trajectory ribs is that lines automatically extend (up to closest surface ).

Please see sample picture

It's hard to understand what you want.  If it's so easy to create it in SW, do that, then post a pic or 2 so we can see what you really want.

The lines you drew already are the centerlines of a rectangular feature correct? A thin wall?

 

Make all those lines construction.

 

Use center point rectangle and select the center of each construction line. 

 

Finish off each rectangle at the extent of each construction line. 

 

Set all the widths equal to each other or individually if needed and set width value

 

Extrude.

that what we do today.

think how much time it's take. not to mention that should you need to change something now its becoming a nightmare.

The Creo best practice in general terms is to keep sketches as simplified as possible. When you define the 50 ribs in a single sketch I would expect it to become unwieldy when extruding all 50 of those lines in a single feature.

 

Have you looked at a UDF for the solid rib features? You would have 50 rib features, but they could in theory be driven from your single sketch of the rib centerlines.

 

If you explain the design intent behind how the rib locations and sizes are determined that may lead to some better ways to control the definition inside Creo.

I would suggest creating a sketch of the center line of each rib then create a mapkey to automate extruding each rib.


There is always more to learn in Creo.
