Of course, you can describe the product, but we recommend that you make a sketch by hand (this shortens the story and deadlines for creating the requested offer). At the end of the questionnaire, there is a field called Document which you can use to “attach” a sketch, drawing, complex technical documentation, or even a photo – send an attachment.
Very often customers have a sample. In that case, fill in the questionnaire, take a picture of the sample, and we will contact you to pick up the sample or come to the place to measure and collect data for the technical drawing.
