You could do it in excel then export the cells to a text file. If you rename the file as Robot text file (.str), then you can import it.
The text file would probably look like this.................you could automate that easily in excel
COMbination # 150 1.2DL + 0.4LL [PLAT] + 1.2LL [EQUIP] + 1.0 WIND [Z] ULS 10 1.2 20 0.4 30 1 21 1.2 2 1.2 1 1.2 COMbination # 160 1.2DL + 0.4LL [PLAT] + 1.2LL [EQUIP] + 1.0 WIND [X] ULS 10 1.2 20 0.4 31 1 21 1.2 2 1.2 1 1.2
The API guru's probably know a better way to do it though........ 
Thanks. I'm not sure if we're talking about the same though. You seem to be listing load combinations whereas I'm working on load cases and Robot's "Load Types" dialog box (see image). Is your method still relevant? If so, where do I find the import function for *.str files?
well, the same would apply.
I'd save an existing Robot file as .str so you get the format. Then you can add your load cases......I've used the method a few times
eg....
LOAds CASe # 1 DEAD LOAD SELf-weight 1to30 CASe # 2 SDL
etc etc
Then you can insert.....
Bjorn,
Some explanations:
Using Excell without VBA
- not possible to create simple case by ordinary copying by clipboard contents of excel file to robot Loads table
- possible to add \ modify loads to existing load cases by copying by clipboard (of course cells data \ order should be the same as in robot Loads table \ Edition tab ; keep in mind that some excell cells may need to have cells format Numerical instead of General)
- possible to create combinations this way but without controlling its number ; modification possible
Using Excell WITH VBA
- you can do whatever you want if you write small macro
I am attaching simple macro to create (not modify - to do so it is needed to add some code to macro) Simple cases - Basic tab in attached Excel file
There is another macro on Combinations tab where you can define (not modify - to do so it is needed to add some code to macro) combinations and then generate them in Robot basing on cases from Basic tab. In this file as a default 20 cases can be used , if you need more cases - add more columns and specify correctly data in cells in row 4
STR File:
If you want to play with it (NOTE: not all kind of loads are supported by this format for eg panel \ countour loads) :
- syntax described here : "c:\Program Files (x86)\Common Files\Autodesk Shared\Structural\Help\2012\R97mod01.doc" ;
some str file examples can be found here: c:\ProgramData\Autodesk\Examples\Example.001

Small modifications in macros codes to enable modification of existing cases \ combinations.
Excel file attached.

Rafal,
As always your spreadsheets are awesome and super helpful.
BUT: I trialled the combination modification one last night. I had 20 or so combinations already in my model. There is no button on the spreadsheet to import to excel the EXISTING cases / combinations. So I cut and paste instead.
Then I change some factor definitions etc, then hit the button to update my Robot file. The Combinations went completely crazy. Some combinations that only had 3 cases ended up with 5 or 6.
So, being too lazy / inept / bad at code to modify your sheet by myself (
), is there any chance it could be updated to;
- Allow dumping the existing cases / combinations into Excel,
- Fix the minor bug experienced when reimporting.
I know you just sit there all day with nothing to do anyway, waiting to write VBA for me...............

Tony,

You can not copy easyly combinations from Robot. Take a look at cells order in robot Combinations table:
casenumber ; coeff; casenumber ; coeff....
In Excel : cases are "columns" so in cells of combination rows you need only coeffs in proper columns.

Small update in attached file.
Possibility to make nested combinations.
Limitation: max 23 simple cases can be used; But of course xls and macro can be modified to handle more. Have fun :-)There are just 26 columns for combinations in sheet but if you want more just create columns like precedent ones (contents of row 3 and 4) - no modification of macro is required in this case.

Dear Rafal,
If I understand correctly, for now we can't read/write Subnature type via API. Maybe I'm wrong?

We can read it by .NatureName
Unfortunately we can not set subnature by API.

Could you create Development Request for this issue please? Because this is a very need for work with Revit+Robot.
