Banana Bulkhead - Part copying in an assembly

Banana Bulkhead - Part copying in an assembly

Banana Bulkhead - Part copying in an assembly

(OP)
I am making a big paper mache banana (for the sake of this example).

I have my banana shape (shelled) (6ft long) as a part.

I bring this into an assembly (fixed) and create reference planes at assembly level which coincide with bulkheads I wish to place within the banana model at 1 foot spacings.

I create a new in-context part based on the first of these planes, and use the intersections with the inside faces of the banana to create the shape of the bulkhead, which I then extrude 1/4inch.

Now I want to create the remaining bulkheads. I could repeat the above process but I should (to my simple mind) be able to copy this first part with its references and place them (paste?) into the new positions in the assembly as new parts. Each new bulkhead part should recognise that the skin shape and intersections are different at the new position and update the bulkhead shape accordingly.

I cannot figure out how to do this. I look forward to seeing answers to my Banana Bulkhead problem.

RE: Banana Bulkhead - Part copying in an assembly

In-contexted parts should not be copied because of the references. Make sure its how you like it and break the references to copy them otherwise make the next bulkheads the same as before.

RE: Banana Bulkhead - Part copying in an assembly

I'm just wondering, as a hypothetical, if your banana started out as a right circular cylinder generated as a surface of revolution, and you did copy the bulkheads without breaking the references, and you then modified the generator line of the cylinder into a banana half, how spectacularly would SW explode?

RE: Banana Bulkhead - Part copying in an assembly

In-context references are tied to the specific instance from which they originate.  Future instances do not adapt, but rather look to the instance that governs the context.

How do you like that for a non-answer?

Have you seen 2012 yet? If not, go see it and I would say that is about equivalent.

Hi Chaps

I appreciate your answers - perhaps using copy is not the answer. Is there some sort of smart part function that might make this work?

Cheers

RE: Banana Bulkhead - Part copying in an assembly

If you create a copy of the mating surface inside your part, you could then use that surface to create your trim contours.  Use a single cross-section plane and control the position of that plane for different configurations, and you will have a part with configurations with a contour that updates according to its position.

RE: Banana Bulkhead - Part copying in an assembly

Here is a half baked idea...
  1. Create a single body which completely fills the interior of the bananna.
  2. Use a cut extrued to remove the areas between the bulkheads.
  3. Save the resulting solid bodies out as parts.

RE: Banana Bulkhead - Part copying in an assembly

(OP)
Ok - The Tick might be onto something, however I am not wanting different configurations of a single part, I want individual parts.

The banana is a simple test, my purpose is to establish a way of spending some time creating a part with quite a few features, and then copying that to different locations where the outside shape has changed, and having the part update to the new position it finds itself in.

If I simply move the existing part I made (by changing or moving the sketch plane) then this principle works. But only for the part I have spent some time creating. It seems very difficult to make a copy of the part and re-establish or reset the context.

1 bunch of banana's to the person who cracks this.
 

RE: Banana Bulkhead - Part copying in an assembly

Use Insert --> Part to bring the banana into the bulkhead (quit snickering, let's keep it clean, boys!).  Then position a plane and make the bulkhead like I suggested before.  Keep copying the part and repositioning the plane.
