Development of a 4-layer printed circuit board

A performer is needed to carry out similar work in Autodesk Inventor. Task: process 245 DWG drawings, in one DWG file one sheet, place the necessary dimensions and annotations according to the sample (dimensions 2-3 and 2-4 annotations); check the correctness of the formatting; export each drawing to PDF. The work is similar, the same formatting principle is used for all files. All necessary views are located on the sheet. All additional information and files will be provided to the selected performer, and a test sample for 5 files will also be offered.

We need a design engineer or a spring design specialist with experience in calculating and developing design documentation. Required tasks: calculate spring parameters according to specified technical requirements and samples; select the optimal material according to operating conditions; determine the main geometric parameters (wire diameter, outer/inner diameter, number of turns, pitch, length, etc.) from the provided sample; perform verification calculations (stress, working stroke, resource, safety margin); prepare drawings for further production; provide a specification indicating the material and main technical characteristics. Types of springs: compression springs; extension springs; torsion springs (if needed). Requirements for the performer: experience in spring design; knowledge of standards (DIN, EN, ISO, GOST or similar); understanding of spring manufacturing technology; At the beginning of cooperation: The development of several springs is planned. If the cooperation is successful, long-term collaboration with regular orders is possible.

I have product patterns in plt format in 4 sizes. It is necessary to create a layout that is as convenient as possible for cutting at widths of 139 cm and 150 cm.

We are preparing to open a primary healthcare clinic (first floor, ~200 m²). There is a current layout plan with dimensions (PDF in attachments) and photos of the premises. The main area is an open space of 109.26 m² with panoramic windows along the arc and round columns. What needs to be done: Planning solution. Place 4 additional doctor’s offices in the open area of 109.26 m², while maintaining the reception, waiting area, access to the procedure room, restrooms, and emergency exits. The offices should be approximately 10–14 m², preferably with natural lighting. The solution should be budget-friendly: lightweight partitions (aluminum/drywall, as in the photos already installed), without major changes (but we are ready to consider alternatives). Minimal interior design concept. A unified palette and materials for the entire clinic (walls, floor, lighting, reception, waiting area), navigation within the premises. No expensive decor — clean, bright, modern, “medical.” 2–3 visualizations of key areas (photorealism is not mandatory). We have a brand book. Facade concept. The exterior appearance with the clinic sign and window decoration, 1–2 angles. Minimal interventions, no reconstruction. Drawings. Updated plan with dimensions and explication — PDF + output (DWG or similar). In your response, please indicate: cost (can be phased: plan → design → facade), timeline, examples of similar work (medical/commercial premises — a plus). We are open to considering options from beginners.

“Good day! I need to develop a drawing of a machine (device) for stitching sheets of agricultural crops. I will provide photos and video materials. Main requirements for the project: Simplicity of design: The machine should be as simple as possible to manufacture and assemble. It is preferable to use readily available materials that can be easily purchased. I understand that some parts will still need to be made individually (custom-made). There are no obstacles with shaping (bending) sheet metal and welding work. Reliability and minimal maintenance. Desired power supply is 220 V. However, I leave the final decision to you — as specialists, you know better which option will be better and easier to implement. Below, I am adding videos with examples of similar machines, as well as videos of similar devices for stitching brooms — perhaps some design solutions can be borrowed from there for our project. Have a great day, I look forward to your proposals!” https://youtube.com/shorts/rT6q4pa_VSY?si=_6iCZLlPV0YXvtUo https://youtu.be/V9nMWLxpIbA?si=xfFpMIFf6qxE0WRB
