DMU & Change added elements type problem

IbrahimNaeem — Wed, 06 Jun 2018 22:42:53 GMT

Hello Gents,

I've implemented a DMU that works fine when I use

Doc.Delete(Elementid);

but when I want to change the family instance type using the following

MyFamilyInstance.ChangeTypeId(MyFamilySymbolId);

runs into problem but problem with not the script I'm using to change the type because I used already before with an external command and worked fine.

I think the problem is : changing the type inside the DMU context.

Any Suggestion would be highly appreciated.

Thanks, Ibrahim Naeem

Different actions have different priorities.

Certain actions can only be performed before certain others, not after.

Maybe you are attempting to change the type too late in the modification chain.

You can influence this by setting the trigger action and DMU priority:
