Hello sir, I am a mechanical engineer with more than 4 years of experience using CAD software such as SolidWorks and AutoCAD, do you have any concept in your mind that we can use as a starting point? Do you have similar models images/pictures (that looks like what you want), can you get or do you already have the measurements of the space where you want this office to be done? Do you want just the plans or you would like a 3D model as well?
