Structural Sketch to DWG Conversion

I have several hand-drawn structural sketches—mostly of building elements—that now need to be rebuilt in AutoCAD and delivered as clean DWG files. Every line, dimension and annotation must match the originals with engineering-grade accuracy, so I can move straight into analysis and detailing without redrawing anything.

Because the set covers more than one structural type, I expect separate model spaces or clearly organised layers so each system is easy to isolate. I have no predefined drafting standard to follow, therefore I will rely on your recommendation for lineweights, layer naming, text and dimension styles that align with common professional practice.

Deliverables
• One DWG file per sketch (or logical grouping) with layers, blocks and annotation fully editable
• Dimensions and structural members placed to exact scale and position
• A brief PDF plot for each DWG so I can review layout before approval

Please mention the AutoCAD version you will use and your typical turnaround per sheet when you respond.
