My favorite for accuracy is revit- but it can be hard to learn and costly.

I would probably just stick with sketchup- easy to learn, lots of online tutorials and free-cheap.

Thanks for your comment, is it possible to import your own designs in these programs? And what is your opinion about vectorworks?

Thanks for your answer! Want to use interior design software for theme hotels/resorts, thats why the function for importing your own furniture/decoration is important to get the right ambiance feeling across to the ones I show it to. To make these products with my laser I am using different programs like fusion 360, solidworks, ai, coreldraw etc.

You'll want to use something like Revit then, or if you're looking for something to start with and free I'd agree sketch up is the way to go. I think you'll find that with the programs you are using importing and exporting into vwx will be clunky and possibly inconsistent. Revit also plays well with autoCAD which, in theory is more likely to be used by the architects/engineers you'd be working with on those kind of corporate projects.

Thanks for your information! I am going to look for revit, fusion 360 is also from autodesk so there should be some way to import it into revit.
