Hi
I designed several website with HTML editor and now I would like to add a responsive layout.
I purchased both, RLM and RSD.
My question: can I build a layout with RLM and import it into the exisiting websites or integrate it?

Generally, the process is to do the initial layout (a.k.a., wireframe) in RLM. Open the RLM file in RSD and do a lot of the more detailed work. Export. Make your final changes in HTML Editor.

I would agree for the most part Brian.

If you are in the business making websites RLM is a very stripped down quick tool to through together a mock up website for a potential client. Basically its RSD minus all the bells and whistles.

If your goal is to purchase the software to setup and manage your own website only, then no need to own both applications as RSD can do almost anything RLMP can do. If this is the case all you need to do is use RSD.

Now to answer Dorothea's question. Yes you can create anything you like in RLMP and open that file in RSD to add as Brian mentioned above.

Good clarification
