"loadURL" would be called from "Load".

I have looked closer at "loadURL". It does not result in a Draw 
document, but always uses "private:factory/simpress*" and 
DocumentType::Impress. A Draw document can be opened as Impress 
document. But that is not usable for me, because the layer feature is 
one of the differences between Draw and Impress documents.

It seems, I need to extend it to get a Draw document.

BTW, SdModelTestBase has a lot of references to Calc. Copy&Paste left 
over or intentional?

I have used CPPUNITTRACE=TRUE now, opened the interesting files and set 
breakpoints before actually starting.

You are right, "save" works, beside the wrong factory.

No, "save" has "private:factory/simpress*" too.

Already that fails. The "office:" prefix is the problem. It seems, that 
for class SdMiscTest, where I put my test, the part "registerNamespaces" 
is missing.

I am the first one who works on a "Draw" unittest?

Kind regards
