    How to Set and Neutral Position

    Blair Frandeen

      I am having a lot of difficulty using the "Set as Neutral Properties" and "Restore Neutral Properties" commands. I am working on a storyboard with a very large assembly, and I keep having to add components by importing them as .step files. Quite often these components need to be translated and rotated into their correct position. Once in the correct position, I want to set that position as the neutral position.

       

      My process is that I select the part I just imported in assembly selection mode and click "Set Neutral Properties." Then I switch to part selection mode and click "Set Neutral Properties". Then I click "Restore Neutral Position" (or ctrl+R) and the parts go back to where they were when I imported them. I press ctrl+Z to get them back to where I wanted them, then repeat selecting them in different ways and clicking "Set Neutral Properties" several times, sometimes selecting the entire ROOT assembly and clicking "Set Neutral Properties." Sometimes this works, and sometimes when I press CTRL+R they parts STILL go back to the wrong place!

       

      Can somebody please explain the black magic I need to use to make "Set Neutral Properties" work correctly?


      Thanks for your help

          Hi Blair,

           

          your way to set neutral properties seems to be correct, but be sure, that there is no other property selected in the Properties menu.

           

          If you want to set a paticular property like Color, you will be able only to set this property by using "Set as Neutral Properties"

          In this case select the actor/part/assembly, second select the property and than use "Set as Neutral Properties"

          But there is no Property to set the Position. In this case you have to deselect all properties and than use "Set as Neutral Properties". This will set ALL PROPERTIES of the actor inclusive the Position.

          First image shows the selected Color, second Image without any selected properties!

              I've been doing what Dirk has suggested, and I'm still not able to get my part's neutral property to to update just as Blair described.  I dont make any changes in assembly selection mode though.

               

              I have no problem with positioning and neutral positions in animation mode, but view mode is not working out the same since I'm not setting keys.

                  Nikki and Blair,

                   

                  Have you tried shutting off assembly selection mode? Composer can be a finicky program in general, and while I personally have never had issues with setting neutral positions/properties in general, every assembly is different and the way some mates are applied or how some parts are created within solidworks can impact how Composer behaves, especially when step files are involved. I'll be honest and say that I have no proof that this will fix the issues you are seeing, but I know assembly selection mode behaves a decent amount differently from the regular selection mode and that step files can cause some funky stuff to happen.

                   

                  Perfect example:

                  The document I am working on right now is a very large assembly. One of the parts is a off the shelf part and our model for it was made by converting a step file to a solidworks part file. depending on how this conversion is done you can end up with a bunch of different versions of the "final" part, whoever did that at my company converted it in a way that there were no actual features on the part, only a set of intersecting surfaces. When I imported the assembly into Composer it showed the part in the assembly tree, but it was unchecked(hidden) and if I clicked the check box to make it show the part the program did nothing at all. I needed to re-import my assembly with a slightly different setting to make it so that composer would accept parts that were only a compilation of surfaces as opposed to a true solid part, all this because that 1 part was originally a step file before it was a solidworks file. If you are importing the step files into Composer without ever having them be solidworks files then it could potentially behave even crazier, but I'm really not sure.

                   

                  Just a thought that popped into my head, sorry I can't say anything with more confidence.
