A rough sketch means an uncertain quote, back-and-forth and sometimes a part that doesn't fit. The drawing is made so the part comes out right first time.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Mechanical part drawings</h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3D model of the part, from a sketch, an existing part or an idea;</li>\n\n<li>2D drawing dimensioned and toleranced to ISO standards: fits, geometric tolerances, surface finishes;</li>\n\n<li>material, treatment and finish specified;</li>\n\n<li>workshop-ready files: PDF for the drawing, DXF for laser or waterjet cutting, STEP for CNC machining.</li>\n</ul>\n\n\n\n<h2 class=\"wp-block-heading\">Strength calculation of a part</h2>\n\n\n\n<p class=\"wp-block-paragraph\">Will a modified, lightened or differently-made part hold? Calculation answers before manufacturing: stresses, deflections and safety factor, using strength of materials or simulation (ANSYS, RDM Le Mans). The result is explained simply, with the areas to reinforce if needed.</p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>choice of a thickness, cross-section or material;</li>\n\n<li>checking a bracket, a tab, a shaft or a weld;</li>\n\n<li>comparing two solutions before manufacturing.</li>\n</ul>\n\n\n\n<h2 class=\"wp-block-heading\">Who is it for?</h2>\n\n\n\n<p class=\"wp-block-paragraph\">Individuals having a part made, craftsmen and small workshops without a design office, project owners consulting several manufacturers. For a part to be designed from scratch, see also <a href=\"https://volkengineering.fr/en/pieces-sur-mesure-moto-auto-nautisme/\">custom mechanical parts</a>.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions</h2>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>I only have a hand sketch: is that enough?</summary>\n<p class=\"wp-block-paragraph\">Yes. With a few dimensions, photos and the intended use, the sketch becomes a 3D model and then a proper drawing.</p>\n</details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Does the calculation count as certification?</summary>\n<p class=\"wp-block-paragraph\">No. A calculation report checks the sizing; some equipment (lifting gear, vehicle parts subject to type approval) is also subject to regulatory procedures and dedicated bodies. This is flagged from the start.</p>\n</details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can I give the drawing to any workshop?</summary>\n<p class=\"wp-block-paragraph\">Yes.
