I need to modernise my AutoCAD Civil 3D survey template so I can print confidently in more than one size without rebuilding a title block every time. The core layouts have to cover 11 x 17 in (ANSI B/Tabloid) and 18 x 24 in (ARCH C) in both landscape and portrait, with smart scaling already wired into the viewports. If you have an efficient way to add 8.5 x 11 in or 24 x 36 in without bloating the file, that would be a bonus. Each sheet must include a title block whose attributes are driven by a single prompt or dialog—enter the details once and they populate everywhere. The fields are: Project #, Drawn by, Address, Lot, Block, Date, plus room for any extra project-specific note I might add later. Whether you build this with block attributes, Sheet Set Manager fields, or another cle...

I need a clean, moderately detailed schematic that explains the workings of a portable air-conditioner in a modular arrangement. The drawing must clearly show the compressor, condenser and cooling fan, with refrigerant and airflow paths called out so anyone reading it can instantly follow the process. The end result will feed into a product concept deck, so clarity at both A3 print size and slide scale matters. I’m happy with AutoCAD, SolidWorks DraftSight, Visio—whatever CAD tool you prefer—so long as the layers remain editable. Acceptance criteria • Compressor, condenser and cooling fan shown and labeled • Distinct, modular blocks with interface points between them • Flow arrows for refrigerant and air paths • Source file (DWG, SLDDRW, or V...

I’ve already sketched and modelled a sleek, pen-sized instrument that fuses four everyday essentials for medical-device reps: a fine-tip pen, a permanent marker, a rechargeable laser pointer, and a concealed, auto-retracting ceramic blade for opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechani...
