I’m looking for a knowledgeable mechanical drafter to walk me through a one-hour, live screen-share session focused on reading detail drawings used in manufacturing. My main goal is to confidently interpret the basic symbols, notations, and call-outs that appear on fabrication prints so I can reduce errors on the shop floor. Ahead of the call I’ll send a PDF of a typical part drawing. During the session I’d like you to: • Explain how to navigate the title block, revision table, and view arrangement. • Decode common GD&T symbols, surface-finish marks, and hole call-outs that control machining steps. • Point out best-practice cues for weld prep and part inspection even if they’re only hinted at on a detail sheet.

I need a compact laser-based device that can track a golf ball in real time, capture its rolling speed frame-by-frame, calculate deceleration, and then switch seamlessly to measure vertical bounce height as well as the ball’s speed just before and after impact with the ground. Rolling speed data is the top priority, yet the bounce metrics are still essential to the overall solution. Because I’ll be moving the unit between an outdoor green and an indoor practice mat, the optics and housing must cope with varying light levels, surface colours, and the occasional speck of sand or moisture. I expect millisecond-level timestamping on all speed and deceleration outputs, delivered either through an onboard display or a simple USB/BLE data stream that I can log to a laptop. Pleas...

Every morning my iPhone has to be woken, a six-digit PIN entered, a work app opened, credentials typed, several form fields completed and a digital signature placed. I want that entire routine removed from my hands by a small desktop robot. Core flow • Wake the phone from sleep by pressing the side button. • Physically tap the screen to enter the PIN code—no Bluetooth, Face ID or Touch ID, just precise mechanical interaction. • Launch the target app, wait for it to load, populate the login screen and navigate onward until the signature page is reached and signed. I imagine a compact gantry or articulated arm driven by servos or steppers, guided by a microcontroller (Arduino, Raspberry Pi, or similar). Because the touch targets are fixed, a predefined set of c...

I need the two attached OpenSCAD files modified so I can 3D print a part. I feel like I have it 95% complete. I have two hemispheres of a 42 mm diameter sphere. Each hemispheres contains half of matching channels and pockets that will accept .051" diameter wires with knots on the ends. The two hemispheres snap lock together using 8 male snap tabs and 8 female snap slots. All of that is already designed and I've uploaded the files. I have a couple of other groves I need created to fit a formed wire that is attached in the PDF. I need help modifying the two hemispheres to accept the attached formed wire that will go through from 0 degrees to 180 degrees. The two eyes of the formed wire extend beyond the sphere. One part of the formed wire goes all the way through the sph...

I have a set of detailed specifications for a series of aluminium-and-glass windows and doors and need them brought to life inside StarFront. All profiles, hardware choices and performance criteria are already defined; what I am missing is someone comfortable enough with the software to translate those specs into accurate StarFront projects that my production team can pick up without a hitch. Your job is to set up each unit, verify dimensions, assign the correct profiles and accessories, and make sure all parameter calculations run cleanly. Once everything balances, export the fabrication drawings, glass sizes, and cut lists straight from StarFront so I can hand them to the workshop. I will supply the spec sheets and any catalog data you may need at the start. Please let me know your exp...

I’m developing a new mechanical component and need precise 3D models created directly in AutoCAD. The work is strictly mechanical design—no electrical or civil cross-overs—so familiarity with standard mechanical tolerances, fits, and industry drawing conventions is essential. My priority is an accurate, parametric 3D model that I can update as dimensions evolve. If you normally build in SolidWorks or CATIA, that’s fine as long as the final files land in AutoCAD format without loss of fidelity; native .dwg is my preferred end point. Deliverables • Fully editable AutoCAD 3D model of the part/assembly • Exported STEP or IGES file for downstream simulation • A short drawing pack (PDF) showing critical dimensions and exploded view I’ll share...

I’m finalising the plumbing package for a commercial project and need a set of shop drawings that drills down into every specification. The scope covers three systems: water supply, drainage, and gas piping. I already have the architectural and structural backgrounds in DWG; what I need from you is a fully coordinated plumbing layout that can go straight to our installers and the approving engineer without additional mark-ups. Depth of detail is important here. Line sizes, slopes, pipe materials, fixture connection points, valve locations, clean-outs, vent routing, isolation details—the whole lot must be called out and keyed to recognised symbols. Wherever manufacturer data is needed (e.g., backflow preventers or pressure-reducing valves), reference the exact model numbers so ...
