Sort of like a microsoft paint box with paint tools. Need it for a work-order form that I use for remodeling quotes. Been trying to go digitial for decades now but just can't find a digital, searchable form creating software in a popular file format to be able to do that.
You want to be able to add an image to the form (we do support that) or you want the ability to sketch something when you fill out the form (we don't support that)?
Although we do not support sketching in the actual HTML form, we support file attachment (for HTML form) so the sketch can be done outside or FormsCentral and then attached to the form submission.
