Connect your ARCNM account to price parts from a STEP model or a DXF flat pattern (a PDF drawing adds tolerances and finishes), see what a calculation costs and why (material, machining, setup and overhead, with a prediction band), rank the cost drivers of a design, compare calculations, try what-ifs such as another lot size before re-pricing and find the lowest-cost lot size. Each operation is a typed tool; writes such as starting a calculation are marked as writes. Running a calculation uses the connected organization's ARCNM calculation allowance. Billing, credentials and account administration stay in the ARCNM app. Access is limited to the connected account's organization and token scopes. ARCNM's figures are estimates for decision support; check them before commercial commitments.",
