Nesting Utility 2019.3 - What's New??

javiar · ‎02-06-2019

Nesting Utility 2019.3 is now available and brings some exciting improvements. Ever wonder if your inventor sources are nestable or if they will get extracted successfully? For the first time ever, it is possible to author sources from within design document to visualize nestable profiles before beginning nesting workflow. This allows users to make necessary changes to ensure desired nesting profiles are passed further downstream – “what you see is what you get”. Nested results can now also be saved as an assembly document that references original source parts.

Release highlights:

Nest Authoring feature for modifying nesting properties of source files.
3D Representation for source files – “3D Extruded”, “3D Detailed”, and “3D Compare” views.
Assembly creation w/ Create 3D Model command: Extruded shape (sheet metal) or the Original 3D source (non-sheet metal).
New languages supported: French, Spanish, and Italian.
Extractions improvements for Generic CAD source files.
Improvements for invisible and derived sketches to be used for nesting.
Construction lines for Inventor Part provider are now ignored, as expected.
Improved shape number display in Nesting Properties dialog box.

and more...

Video below shows a quick overview of the top 3 features included in Update 2019.3.

For additional information on the new capabilities, please visit the online help document at https://help.autodesk.com/view/TNNUINV/ENU/. Besides these highlights, there are several bug fixes and other improvements.

Sample dataset, class handout, and the session recording from our "Nesting Utility Hands-On" lab at Autodesk University (Nov. 2018) are available for download at https://www.autodesk.com/autodesk-university/class/Nesting-Utility-Hands-2018.

As always, we look forward to your feedback. Thank you for your support and patience while we continue enhancing and refining our nesting solution in Inventor.

Downloaded Nesting today and have an issue with the imported source file. I am trying to import multiple .IPT files , and they will all be scaled using the "DIRECT EDIT" function. In the nested file the .IPT models are not to the scaled model. They are the original model prior to the "DIRECT EDIT" scaling command. What am I missing?

Thank You,

It looks like you are using the Inventor Part provider to extract the shape. The Part provider only recognizes extrusions and sketches and ignores the Direct Edit feature. This means the shape extraction will work on the original size extrusion, not the scaled extrusion. That is why you are seeing the wrong scaled part.

Please use the Generic CAD provider instead. That provider will recognize the entire body , even after it is scaled.
This can easily be accomplished by using the Nest Authoring context menu on the part or you can also set the Generic CAD provider on the fly in the Source Provider column of the Sources dialog.

Working Great now.

Between Autodesk's Nesting Utility and Hypertherm's Pronest Software, which is the best?

jpinda · ‎03-19-2019

I use Pronest to make code for a plasma cutter. I have a very long list on what doesn't work that well with Pronest. None of this would really matter if the cost wasn't so high. It does something wrong all most every time I use it. Pronest has a lot of features that we don't use, and or is pointless. The big one is to open *.ipt files and I found that to be useless and a costly add on. We are slowly working out the bugs and it is getting better. They are willing to fix it.

ANU so far doesn't work with plasma. There is a 2d profile for lead in and lead outs and it doesn't work with a recommended cut path for holes. But I am still learning and trying to figure out how to get ANU to work. If I can get ANU to make good lead in lead outs I will drop Pronest.

I have to say sorry I don't think I helped.

Nest Authoring

In the Nesting thickness if I select and over type say ".25" I get 0.52in or 2i5n than that will change to 2in.

We know about problem with 2D profile not respecting preserve order when in computer compensation is used, a fix is on the way.

What would you like to see improved with leads?

Thanks for reporting the issue with the backspace key not working correctly when using numbers containing a decimal separator. I logged this in our defect database as ticket TRUNINV-1781:"Thickness entry in Author dialog not properly working"

I suggest you clear out the thickness field TWICE (to the point where the unit is no longer visible) before entering new values to avoid this problem.

Plasma needs a curved lead out the same diameter as the hole with an over burn. There are a number of methods

and they get involved. I haven't had the time to figure out what I does a 100%. This is the hardest thing to do with plasma. ANU to me has it's order incorrect. I would think you would first setup the lead ins and lead outs.

Let you pick position and style. Then do a nest and let the scrap work for you. I think your software this works with say a water jet. But not oxy or plasma the lead ins and lead outs are to large. The location of them can make a good or bad part. Sorry I have to go back to work. I will try to work more on this later.

Thank you

Dear Everyone

So I tried to use the 2D Profile to make the tool path for a pattern of parts.

The entry position was hard to get to go to the correct spot. Did work well.

So then I tried the nesting. First time!!!! I was thinking that there was lead in and outs set here.

I didn't think so I was hoping. The youtube videos "work flow" didn't look good.

How do I have a nest with .25 part gap spacing with lead in and outs?

The gaps would be set by the part or the leads. I can make a nest but the spacing is always .25.

Made a few test nests (say that 3x). Then how do a fix a nest? What if a part is in the wrong spot.

I used other nesting software and having a perfect nest doesn't happen that often (bobcad & pronest).

Here below is a good nest (from pronest). The part spacing and lead spacing is .25.

When you create the Inventor model of the nest with the 3DModel command and set the type to be Assembly (which is the default option), you can then manually change the position of the assembly components (after removing the "Grounded" assembly constraint).

Thank you for your help.

That's what I thought. So there is no nest report on plate size and or use. I am really sorry to say this but I don't see any value in using the nesting functions at all. I really don't understand the workflow of this.

I use nesting software to arrange parts for the lead ins and outs to work with the scrap. Getting lead ins and outs in the best spot for manufacturing. Also have a report of what's being cut.

So think this software may work with say a waterjet because of the small lead in and outs.
