Нужно н начертить чертежи для контрольной работы.

There are 15 ready sketches of parts with specified dimensions. The parts are already being manufactured based on these sketches, so the main dimensions have been agreed upon with production. It is necessary to convert the sketches into clean technical drawings. As an example of formatting, I am attaching a drawing of a gear. Scope of work: Out of 15 drawings, 3 need to be fully checked: tolerances and fits, roughness, bases, geometric tolerances, and other necessary technical markings. For example, in the attached files "BK left rigid," this is one of four sketches of the bushing; if it is redone, the other 3 are identical and there are also 2 shafts and one wheel. If the specified tolerances and roughness on the sketches are incorrect, they need to be corrected or a suitable option proposed; The remaining drawings are simpler and mostly identical. They can be formatted by checking the correctness of the markings and the absence of obvious errors. We would like to receive the result in PDF format.

Good afternoon, at this stage, we need all plans and facades in dwg. It is very important that the dimensions are accurate, especially for the exterior.

Dear designers and creators of functional wooden furniture, I present to you a mini-project. 1. General Information Subject: Development of detailed drawings for the manufacture of two single beds by custom order with bedside tables. Number of products to be manufactured: 2 (two). 2. References Use the provided photographs (files 1.png, 2.jpeg, 3.jpeg) as visual and conceptual basis. Design: minimalism, massive elements, clean lines, emphasis on the natural texture of wood. 3. Technical Specifications and Dimensions 3.1. Bed and Mattress: - Mattress size: 1000 x 2000 mm. - Mattress height: 160 mm. - Sleeping place height: Designed considering the height of the bedside tables (500 mm). - Base for the mattress: Orthopedic frame with beech slats. The frame construction (rails) should include reliable internal supports for the installation of the slatted base. 3.2. Bedside Tables (freestanding): - Dimensions: Width — 460 mm, Depth — 500 mm, Height — 500 mm (proportional to the height of the bed). - Configuration: Two rows of pull-out drawers. The tables are independent elements and are placed in front of the side panels of the headboard. 3.3. Headboard: - Height: 1400 mm. - Total width: Calculated (Width of the bed + 2 widths of the tables at 460 mm + technological gaps). Approximately: ~1920-1950 mm. - Installation: The headboard is attached exclusively to the bed frame and is an integral part of it. Mounting to the wall is strictly prohibited. - Structure (4 components): - Upper part: Wide horizontal panel across the entire width of the structure. - Two side parts: Vertical panels located behind the bedside tables. Central lower part: A panel located directly behind the mattress and adjacent to the bed frame. 4. Materials and Hardware 4.1. Materials: 100% solid wood. All parts are made from solid wood: visible bodies, facades, headboards, as well as internal boxes of all drawers. Replacements (MDF, particle board) are not used. Finish: Matte transparent varnish. 4.2. Hardware: - For all drawers of the bed and tables, use hidden mounting guides (e.g., Blum Movento, Hettich AvanTech/Actro or analogs). - Opening mechanism: "Push-to-open". No external face hardware (handles) is provided. - Fastening hardware must be hidden where possible and ensure maximum rigidity of the massive structure. 5. Structural Requirements (Assembly/Disassembly) - The product must be designed based on the principle of a modular constructor. - Fasteners (bed connectors, mini-fixes, confirmats, etc.) must ensure easy and intuitive assembly on-site, as well as the possibility of repeated disassembly without loss of rigidity and damage to the wood. 6. Requirements for the Designer/Constructor's Work Result The contractor must provide: - 3D model / Visualization of the developed structure - Complete set of working drawings (front, top, side views with all dimensions). - Assembly diagram of the nodes (especially the connection of the 4 parts of the headboard with the bed). - Specification (detailing) of materials indicating the dimensions of each solid wood part. - Specification of hardware (exact list and quantity of guides and fastening elements). - I also expect questions from you regarding the project regarding the possibility of making up to 4 revisions from my side. Additionally, as a test task, which will also be paid, it will be necessary to design a hexagon shelf. Shelf size Width 350 millimeters Height 400 millimeters. Depth — 130 mm Material: wood (Ash and Beech) Thank you for considering this Mini Project Offer.

Title: Development of electrical schematics (EasyEDA) for data acquisition modules (STM32, precision ADC, galvanic isolation) Task Description: We are looking for an experienced circuit engineer to develop the schematic diagrams for two boards (PCB design is not required at this stage). What needs to be designed: Master module: power input of 24V and communication with the external world via hardware-isolated RS-485. Analog input module: digitization of two channels of industrial sensors (0-10V / 4-20mA). Based on a precision ADC (type ADS1248). A mandatory condition is the presence of an internal digital isolation barrier after the ADC. The boards communicate with each other via SPI. Key requirements (Strict!): Environment: only EasyEDA (Pro or Std). Components: 100% of parts must have part numbers (C-parts) from the LCSC Electronics catalog, as the boards will go for automated PCBA. Base MCU: STM32F103 (or your suggestions for modern equivalents). A detailed, well-written technical specification with a ready reference architecture from Texas Instruments will be provided to the candidate. Bonus: For the specialist who diligently and competently completes this stage (circuit design), a second paid stage — routing of these printed circuit boards (PCB Design) — will be guaranteed.

Welcome! We are looking for an experienced company, design bureau, or high-class specialist (architect/structural engineer) to develop a complete design project and set of working documentation (drawings) for our new attractions. We need not just a beautiful visual, but a ready technical solution that builders and installers can use to implement the project from start to finish. What will be included in the tasks (Scope of work): Concept and visualization Planning solution Working documentation (for builders) Our requirements for the contractor: Availability of a portfolio Ability to work in professional software Understanding of construction technologies, materials We look forward to your responses! Let's create an awesome project together!
