I have several scanned PDF plans that must be redrawn into clean, accurate CAD files right away. The job is strictly a drafting task—no design work—so I only need the basic outlines captured: walls, openings, overall dimensions and room labels. Your deliverable is a fully editable .dwg (AutoCAD-compatible) file that mirrors the PDFs in scale, line-weight hierarchy and layout, plus an exported PDF for quick reference. Speed matters: once I send the scans, I’d like a first pass within 24 hours and the final files shortly after any revisions. If you have a proven workflow for turning raster plans into tidy vector drawings, please let me know how soon you can start and how long the set will take you.

I’m looking for a single professional who can look after both the electrical and plumbing sides of my property.

I need help steering an LLM through a realistic engineering workflow on an open-source Python library. Your first step will be to choose a mature, well-documented GitHub repo that ships as a library or package and can be cloned and built with nothing more exotic than standard pip dependencies. Once the repo is agreed upon, you will frame a single, well-bounded engineering assignment for the model—perhaps a small feature, a non-trivial refactor, or a robust test suite—something neither superficial nor sprawling. From there you will run an iterative review loop: prompt the model, inspect its MR, request changes, and continue until the contribution is truly production-ready. That means the patch must follow project style, cover edge cases, include unit/functional tests, update do...

I have a small script that pulls plain-text content from a series of public web pages, but it has suddenly started throwing runtime errors before any data is returned. The pages themselves load fine in a browser, so the problem is clearly within my code or its dependencies. Here’s what you can expect from me: a zipped folder containing the current Python script, the list of target URLs, and a copy of the last error stack trace. I’ll also let you know which Python version and libraries (requests, BeautifulSoup, etc.) are in use so you can replicate the issue quickly.

My MTech CAD-CAM thesis revolves around simulation and analysis, and I want the core of the work to be a rigorous Finite Element Analysis on metallic materials that can stand up to peer-review and ultimately be accepted in a reputable journal. Scope of work The project begins with selecting a metallic alloy (steel, aluminium, or other ferrous/non-ferrous metal we agree on) and defining a problem statement that contributes something fresh—this might be a novel geometry, an advanced loading scenario, or a comparison of conventional and additive manufacturing routes. From there, the tasks move through clean CAD preparation, high-quality meshing, boundary condition definition, convergence checks, and result interpretation. Validation—either with analytical solutions or published...

I am completing an dissertation that couples CFD with structural-piezoelectric analysis in ANSYS. The core of the study is piezoelectric actuation: fluid flow drives a smart structure, the structure feeds back to the flow, and both responses must be validated against a published research paper. Here is what I need from you: build the clean geometry, generate a high-quality mesh, run the transient CFD in Fluent, transfer loads into Mechanical for the structural and piezoelectric response, then bring everything back together for a convergence study and result comparison. Because this is academic work, every modelling choice has to be fully explainable. I will rely on you most heavily when it comes to solver settings—that is the area I find most challenging—so be ready to justif...

Workbench or APDL are both fine as long as the files load error-free in my 2022 R2 installation. Deliverables • Ansys project file fully set up and solved • Post-processed outputs: contours, plots, and any useful animations • Concise PDF repo...

I need a full seismic evaluation for a short-span concrete girder bridge that measures under 100 m from abutment to abutment. The structure is already conceptually laid out; what’s missing is a rigorous analysis that confirms it will meet the relevant design codes for our seismic zone and highlights any detailing adjustments we should make before drawings go to issue. Here’s what I expect: • Build a 3-D model (SAP2000, MIDAS Civil, or similar) reflecting the current geometry, boundary conditions, and material properties. • Run response-spectrum and, if necessary, time-history analyses to capture the critical load combinations. • Provide a concise report summarising assumptions, key output envelopes (displacements, forces, demand-capacity ratios), and clear...
