Is there a way we can draw a construction diagram in quickbase

No, not natively. It's not designed to create drawings.

Can It integrate with any other software?

It depends what you mean by integrate.  Quick Base is very good at bring data from other apps into Quick Base, but that is referring to data and not say a blueprint.

What is it you are trying to do?

Are you trying to overlay Quick Base data on a floor plan, for example?

Hi Mark,
My company does mold assessment.They inspect the house and have to give abatement's for it we need a basic area diagram as it is part of the report which they have to generate.Is it possible to have a button to navigate to an other software and make this possible?

You can certainly easily create a hyperlink to any website.  If he other website was able to generate a document, you would save that document on your desktop and then go to QuickBase and attach it to a record as a file attachment.
