Index a Parameter Name during Assignment - Ilogic

[Nickefth61]

Hello Inventor Forum,

This is a question about Inventor Ilogic. I have an assembly with 5 parts that are all the same except for a difference in height. The part names are "Part: 1", "Part: 2", Part: 3" etc.  The height parameters are "PartHeight1", "PartHeight2", "PartHeight3" etc. I also have a parameter "NumberOfParts" which dictates how many of the parts are present in the assembly.

I want to write a for loop such that:

for i in range(0, NumberOfParts):

    PartHeight[i] = InputBox("What is the Height of Part" + str(i), "Part Height")

end for loop

I could also do the same thing with a while loop:

i = 0

while i<NumberOfParts

    i=i+1

    PartHeight[i] = InputBox("What is the Height of Part" + str(i), "Part Height")

end While

My question is: How do I index the parameter name "PartHeight1", "PartHeight2", "PartHeight3" etc. during the loop? It throws a syntax error if I do something like ("PartHeight"+str(i)) = InputBox(....). Is there a way to index through the names?

I would rather not hard code in the numbers, because the number of parts in the assembly can increase beyond the point of convenient hard coding.

Thank you!

Nicholas

You may get a better results by posting this question in the Inventor Customization forum: http://forums.autodesk.com/t5/inventor-customization/bd-p/120  Also always indicate which version of Inventor you are using.

Mark,

I will move the posting. Would you say that the customization page is the best place of all iLogic questions?

I'm also adding a tag with my Inventor Version.

Thanks,

Nicholas

iLogic posting can happen here and they do.  Should yours be posted here?  It can, but you may not get any response because you are writing VB/.NET stuff into your iLogic code.

Many users here may use iLogic but they are only using the iLogic functions and may not have any true programming experience.   Where-as the customization forum is probably monitored by those who do have an extensive programming background or experience.

In addition (and this is my opinion)...  I don't considered your code as being iLogic, its VB or .NET.   When I think of someone saying I have a iLogic code, I see their entire code written using only the iLogic functions.  But that's my 2 cents...

Mark,

Thanks for sharing your opinion. I suppose you would be correct in saying that is not true Ilogic snippet code. I tried moving this post and couldn't find the option to do so. Truth be told, I had trouble navigating back to the post after posting it...couldn't find it! Then I remembered the option to see all activity in my account page, and here I am.

I ended up finding the solution to my problem anyway. I'll post it here in case anyone else happens to come upon this post...

To index a parameter, I cannot use the str() code because when it converts my integer to a string, it adds a space. Ilogic has a snippet, Cstr() which converts to a string without the space. With a parameter it would be:

i = 0

while i<NumberOfParts

    i=i+1

    Parameter("PartHeight"+Cstr(i)) = InputBox("What is the Height of Part" + Cstr(i), "Part Height")

end While

The "Parameter" data type can be used not only when assigning parameter names, but when calling them. So if you need to ever index or alter a parameter name, call it, or do anything of that nature, Parameter() can help. I hadn't realized in my lack of experience that Parameter() is actually an Ilogic datatype.

Anyway, thank you Mark for your reply. I hope this helps anyone else having a similar issue.
