Reducer CAD Drawing Generator

Problem

Generating reducer CAD drawings usually involves selecting a model, entering many parameters, reviewing calculated intermediate values, and then iterating on inputs such as module, tooth count, and transmission ratio. Doing this manually against a spreadsheet and a web site can lead to missing fields, inconsistent assumptions, or parameter changes that no longer match the backend calculation file. This skill turns the JXT Mechanical Parts Platform reducer API flow into a structured, step-by-step workflow for engineers.

How It Works

• Lists reducer products and lets the user select one by number.
• Fetches the parameter schema for the selected product, then asks for each input_params value one at a time.
• For dropdown parameters, it performs a preliminary calculation and reads the available options from dropdowns.
• After all inputs are collected, it submits the first calculation and stores the returned filename plus a parameter snapshot called lastSentInputs.
• Later edits use incremental updates: only changed parameters and the same filename are sent, so the backend updates the same Excel file instead of creating a divergent calculation state.
• Results are grouped into inputs, debugging parameters, coefficients, and outputs for review before order creation.
• Guest order creation is supported without login, then the skill polls status every 5 seconds and shows the checklist, output files, and viewing link.

Boundaries and Notes

• It depends on the reducer API under jixietools.com and the fixed reducer category ID 29, so it is not a generic mechanical CAD tool.
• The filename must be retained for incremental calculation and order creation.
• Parameters are asked one by one to reduce input errors, and polling should stay at a 5-second interval.
• The skill prepares and tracks the draft order; purchasing still happens on the website.
