Only top Assembly CAD converts STEP files

Hello @Jungwon 

You can add IBA attribute to the CAD and based on the attribute value you can set publishrules if the STEP should be generated or not. 

for example generateStep = yes

then based on the Windchill Help you can set publishRules to achieve what you need. 

Evaluating Publish Rules

Yes user has to set the IBA attribute in the CAD

An another option is customization with approval process or another workflow process.

You can send the object to visualization with add-hoc publish rule by code.

Programmatically check if the assembly is top one and send it to the visualization with own publish rules. (publish rules has to be activated)

Hope this can help you

You could use publish rules for this - xml config loaded into Visualization Configuration Administration. (https://support.ptc.com/help/wnc/r12.1.1.0/en/index.html#page/Windchill_Help_Center/WVSPublishRules/WVSPublishRulesUsePubRules.html)
