Hi All,
This is our first project fully modelling hull structure in Inventor and utiliaing nesting to get the parts cut. Inventor nesting is proving troublesome though.
With a mixture of plate parts and extrusions, deciding what needs to be nested is quite a manual process. Going having to open the relevant extrusion parts to extrude from nest has taken a while. I am aware of changing the BOM type to purchased will also exclude that part from the nest and havent gone down that route. Is there an alternative way to exlude parts from a nest?
At the moment I have just used the hull structure as the source for the nest and it is inconsistent. As the assembly loads and Inventor starts looking through the assembly and shows a progress percentage in the parent column, this has quite often stopped near the end (90-99%). Inventor has not frozen during this period.
When I have got the source parts loaded and realized there are a few I may have forgotten to remove from nesting, after opening the part to exclude from nest, it still appears in the nest. Re-starting has had no effect.
The structure I am trying to nest has various thickness parts, all Aluminium. However, creating a nest study nests all thicknesses apart from 4mm thick parts. Package material is pre-defined for 4mm parts and they all appear in the row of un-nested parts.
The shell plate parts have been developed and dxf's generated. I have tried importing those as dxf's. This mostly works appart from any text for marking. All text is shown scaled up and off the part, not as it is in the actual dxf file. Has anyone come accross this before?
We have tried creating nests on different machines with the same assembly, but have had very different results after the source has fully loaded. Another user got this after creating the study
Has anybody come accross these problems? At the moment we are frantically trying to get some nest out for quote but at it's looking like a more manual approach might be needed to get these parts output.
Thanks in advance
Nigel
