NX CAD Essentials Beginners Guide: Sheet Metal Design and Drafting Explained (Episode 15) — Updated June 2026 (Updated June 2026)

India's manufacturing sector crossed ₹71,343 crore in committed investment through AURIC alone, and every OEM in Pune, Sambhajinagar, and Kolhapur runs its product design pipeline on Siemens NX. Episode 15 of our NX CAD Essentials series picks up where Episode 14 left off — this time covering sheet metal design workflows and engineering drafting, two modules that come up directly in technical interviews at Tata Technologies, KPIT, and Bajaj Auto. What most people don't realize is that learning these two modules in NX can double your placement chances compared to knowing only part modelling. Here's the complete guide — watch the video above, then read on for everything you need to know.

What is NX CAD and Why Do Auto Companies Prefer It?

Siemens NX (formerly Unigraphics) is the 3D CAD and CAM platform used by the world's largest manufacturers — Toyota, BMW, Lockheed Martin, and closer to home, Tata Technologies, KPIT Technologies, Mahindra Engineering, Bajaj Auto, and Force Motors. Unlike SolidWorks, which is popular with small and mid-sized firms, NX dominates large enterprise environments because of its tight integration with PLM (Product Lifecycle Management) platforms, specifically Siemens Teamcenter. What most people don't realize is that a single NX licence covers 3D part modelling, assembly design, sheet metal design, drafting, FEA (with NX Nastran), and CNC machining (NX CAM) in one unified environment. That's why companies invest in it — their designers, analysts, and manufacturing engineers all work in the same file format, eliminating conversion errors. For a mechanical engineering student in Maharashtra, Siemens NX proficiency is the clearest path into a design engineering role at Tier-1 auto suppliers.

Episode 15 Deep Dive: Sheet Metal Design in Siemens NX

Sheet metal design in NX is built around the real-world manufacturing process — you define the material, gauge, bend radius, and k-factor, and NX automatically calculates the flat pattern for blanking. This is critical because a sheet metal part that looks correct in 3D can be unmanufacturable if the bend allowances aren't set right. In Episode 15, we cover the core sheet metal commands: Flange, Tab, Cutout, Bend, Hem, and Louver. We walk through creating a bracket from scratch — defining the base tab, adding flanges with standard bend radii, creating knockout holes for wire routing, and finally generating the flat pattern layout for laser cutting. Trust me, once you understand how NX calculates bend allowances automatically, you'll never want to do sheet metal in any other software. The flat pattern directly links to a drawing view, which brings us to the next topic.

Module	What You Learn in Episode 15	Industry Use
Sheet Metal Base	Tab creation, material and gauge setup, bend radius definition	Bracket and enclosure design at Bajaj, Mahindra
Flanges and Bends	Flange command, contour flange, jog, hem	Auto body panel design, HVAC ductwork
Flat Pattern	Unfold, k-factor, flat pattern layout for laser cut	Shop floor fabrication drawings at Endurance
Drafting Views	Front/side/section/flat pattern views, associativity	Production drawings at Tata Tech, KPIT
GD&T Annotation	Flatness, perpendicularity, datum references	Quality-approved drawings for Tier-1 suppliers

Drafting in NX: Creating GD&T-Ready Engineering Drawings

The NX Drafting module takes your 3D model and generates production-ready 2D engineering drawings automatically — front view, side view, section view, and isometric, all associative to the model. Change the 3D part and the drawing updates. This is a massive time saver compared to re-drawing in AutoCAD. For sheet metal specifically, the flat pattern view is critical for the shop floor — it shows the fabricator exactly where to cut and where to bend. In Episode 15's drafting section, we cover view creation, dimension styles, GD&T (Geometric Dimensioning and Tolerancing) callouts for flatness and perpendicularity, part list annotation, and title block setup. These are exactly the deliverables a Design Engineer at Bajaj Auto or Endurance is expected to produce on day one. Interviewers at Mahindra Engineering specifically ask candidates to demonstrate a drawing view setup in NX — this episode prepares you for exactly that.

NX CAD vs SolidWorks vs CATIA: Which Should You Learn?

Here's the thing — the right CAD software to learn depends entirely on where you want to work. SolidWorks is popular at small to mid-size companies and startups because it's affordable and easier to learn. CATIA is dominant in aerospace, railway (BEML, Alstom), and premium automotive (Tata Motors body engineering). NX is the standard at large Tier-1 auto suppliers, defence contractors, and companies using Siemens Teamcenter PLM. For students in Pune, Sambhajinagar, and Kolhapur targeting Bajaj Auto, KPIT, Tata Tech, Mahindra, Force Motors, and Bharat Forge, NX is the clear priority. If you already know SolidWorks, picking up NX takes 3–4 weeks of focused practice because the modelling logic is similar — only the interface and terminology differ. If you're starting fresh, NX is still worth learning first for the Maharashtra job market.

NX CAD Jobs and Salaries in Pune, Sambhajinagar, and Beyond

NX CAD professionals in Pune earn ₹3.5–7 LPA at entry level (0–2 years experience), ₹7–13 LPA at mid level (3–6 years), and ₹14–22 LPA as senior designers and NX PLM administrators at companies like Tata Technologies Pune, KPIT Technologies, and Mahindra's Engineering Centre in Pune. In Sambhajinagar, Skoda VW Shendra (Plot A-1/1) and Bajaj Waluj (Plot G-137) hire NX CAD designers for body and chassis component work, typically at ₹3.5–5.5 LPA for freshers. Endurance Technologies (E-92, Waluj MIDC) and Toyota Kirloskar in the AURIC belt are also active NX users. Sangli's SMMMA member companies (250+ industries in Kupwad MIDC) and Kolhapur's Bharat Forge Kagal plant round out the regional hiring picture.

Maharashtra students can use the CMYKPY (Chief Minister's Youth Kaushal Yojana) scheme for a ₹6,000–10,000 training stipend on approved CAD courses. Contact our admissions team to confirm your eligibility and get support with the application process.

FAQs

What is covered in NX CAD Episode 15 of ABC Trainings?

Episode 15 focuses on two modules: sheet metal design and engineering drafting in Siemens NX. The sheet metal section covers tab creation, flange and bend commands, k-factor setup, and automatic flat pattern generation. The drafting section covers view creation (front, side, section, flat pattern), GD&T annotations, dimension styles, and title block configuration. These are the deliverables hiring managers at Bajaj Auto, Tata Tech, and KPIT expect candidates to demonstrate.

Is Siemens NX better than SolidWorks for getting jobs in Pune?

For Pune's Tier-1 auto supplier belt — Tata Technologies, KPIT, Bajaj Auto Akurdi, and Mahindra Engineering — NX CAD is the standard platform, giving it a clear edge over SolidWorks for those specific roles. SolidWorks is more common at smaller companies and product startups. If your target companies use Siemens Teamcenter PLM (most large OEMs and Tier-1s do), NX is the tool you need. Both are good skills; the choice should follow where you want to work.

What is the starting salary for an NX CAD designer in Maharashtra?

Entry-level NX CAD designers with 0–2 years of experience in Pune earn between ₹3.5 and ₹7 LPA depending on the company and specific module expertise. Companies like Tata Technologies and KPIT pay at the higher end; smaller Tier-2 suppliers pay ₹3.5–4.5 LPA to freshers. In Sambhajinagar's AURIC belt (Skoda VW, Bajaj Waluj, Endurance), fresher NX designer roles start around ₹3.5–5.5 LPA. Salary data from AmbitionBox and 6figr, June 2026.

Can a diploma holder learn NX CAD and get a job at Bajaj or Mahindra?

Yes, diploma holders in mechanical or production engineering who complete NX CAD training regularly place at Tier-2 and Tier-3 auto suppliers, and some Tier-1 companies in Sambhajinagar and Sangli. The key is demonstrating hands-on proficiency — sheet metal design, drafting, and a basic assembly — in the technical interview. ABC Trainings' placement program specifically prepares diploma holders for these interviews with live project work and mock sessions.
