Former Solidworks user here turned Inventor user. I'm constantly running into roadblocks where I knew how to do something that Inventor just will not do. One of these is sketch driven locations of parts in an assembly.
I'm tasked with locating a number of widgets in a case while taking up the least foortprint while affording the best amount of space between each widget. Formerly in Solidworks, I would contrain the planes of the widgets to a sketch and drag the sketch to adjust the size of my footprint.
Not surprisingly, this is a feature that's not intuitively available in Inventor. What would be the Inventor way of approcing this task? Make me love Inventor. Thanks!
Solved! Go to Solution.
Solved! by jeanchile. See the answer in context.
Hey jeanchile, thanks for responding so quickly!
Maybe I'm blind, but when I choose the constraint option, I can select the features on the part no problem, but I'm not able to select the sketch entities. Is there some check box somewhere that allows you to select the sketch features? I've already tried changing the selection method from "Select Component" to "Select Sketch".
I'm working on making a sketch in a separate part to place in the assembly. I'll letcha know how it goes.
This was in fact the case. I needed a sketch inside another part that was inserted into the assembly in order to constrain to the sketch. Seems really like a really backwards way of doing this, as I now have another layer of procedure to work my way through, and another part file sitting in a folder.
Can anyone offer an explaination as to why this is necessary?
While I'm certainly not qualified to speak intelligently about why the sketch needs to be in a part file I can offer my thoughts. In Inventor the assembly sketching tools are utilized primarily for creating assembly level feature like certain holes, machining features, etc. Using them for other things is permitted but usually not the best workflow.
Now that you have an effective "work-around" to accomplish the task at hand, it's at this point that I am going to ask a few further questions in hopes of determining a better method to achieve what you are after. Hopefully the really smart gurus like Curtis, JD, blair, et al will chime in here as well.
1.) What version of IV are you using (year and model)? YOu should consider putting this into each post so others can determine the proper help.
2.) Do you do this kind of case design often or is this a once in a lifetime kind of thing?
3.) Have you done a search for "case design" or "shipping container" or something like that here on the forum?
I'm guessing that using derived parts, multi-body parts, or another method is going to be the better choice for you if you do this often.
I'm using 2014 Inventor Standard
We do these cases and others similar quite often, previously in a 2D cad system. I'm looking for the best possible work flow to do this, and so far the process isn't matching up with what I'd be used to doing in Solidworks.
I've looked in to using derived parts via "Make Components" but that starts to get buggy when I add or subtract layers from the parent part. End result is that I need the foam layers to output as a sheet metal file so that it can be sent to our CNC machine. In addition, I'm trying to set up our drawings so that as much as possible is done beforehand.
I'll do some perusing on the forums today regarding case and container design. But anything one might have to point in the right direction would be really appreciated.
I have started working on a program in VB.net that creates an assembly based on a list of parts, with each part having a point defines in the list. The program reads the list, picks the correct part, and places it in the assembly. The list defines the point in the part as XYZ, theta, etc.and uses the point to place it at that location..It isnt finished yet, as I want the program to read the list, look for a part in a library, and place it. If it doesnt find the part in the library, it creates it, and places that new part.
The program is being developed to create an assembled model of a particle accelerator...beam tubes, magnets, etc..When I have time to finish it, it could potentially be used to create any assembly as long as it can read the list of parts, and at least 1 model of each part exists in the library.
(Paul, I think you and I might have talked about this at AU this year..)
