SolidWorks Engineering Drawings: Views, GD&T and BOM Complete Guide (Updated June 2026) (Updated June 2026)

Here's a truth most online tutorials skip: you can be brilliant at 3D modeling in SolidWorks, but if you can't produce a clean engineering drawing that the shop floor can actually read, your design never gets manufactured. With AURIC's ₹71,343 crore manufacturing push across Chhatrapati Sambhajinagar adding 62,405 jobs in 2025–26, and Bajaj Auto running 164+ active CAD and design engineering vacancies at their Akurdi plant, there is no shortage of opportunities — but every single JD lists drawing and detailing proficiency as a core requirement. Episode 15 of our SolidWorks Essentials series covers engineering drawing views, section cuts, GD&T annotations, and BOM generation — the four skills that transform a 3D model into a manufacturing document.

Why Engineering Drawings Still Matter in a 3D CAD World

What most engineers don't appreciate until their first job is that manufacturing runs on 2D drawings — not 3D models. The 3D model tells you the shape; the engineering drawing tells the machinist the tolerance on that 10mm hole (H7/p6 interference fit?), the surface roughness on the mating face (Ra 1.6 μm?), and the datum reference frame for inspection. Without a properly annotated drawing, a machinist at a CNC shop in Bhosari MIDC has no idea how precisely to make your part. In Pune's manufacturing corridor — from Chakan MIDC to Ranjangaon to AURIC Shendra — every tier-1 supplier to Bajaj Auto, Mahindra, and Tata Motors runs production from DRW files or PDF drawings generated directly from SolidWorks. The companies that hire CAD designers in 2026 are not asking "can you model in SolidWorks?" — everyone can do that. They are asking: "can you generate a drawing that a machinist in our Waluj plant can use without calling you for clarification?" Companies like Endurance Technologies (Plot E-92, MIDC Waluj), Skoda VW Shendra (Plot A-1/1, AURIC), and Force Motors Pune (Akurdi, Pune 411035) run ISO and ASME standard drawing packages. If your drawings don't match those standards, you'll be re-doing work on your first week.

Setting Up Drawing Views: Orthographic, Section and Detail

When you open a new Drawing in SolidWorks, you pick a sheet size (A3, A2, A1 or custom), a projection type (First Angle for ISO/European practice, Third Angle for ASME/American), and a drawing template containing your company title block. Once set, the Model View command drops a standard orthographic view — front, top, right, isometric — onto the sheet and keeps it parametrically linked to your 3D model. Any change to the model automatically propagates to the drawing. Section Views cut through the part along a defined line to expose internal features like bore diameters, groove depths, and wall thicknesses — geometry that would be hidden lines in a standard view and hard to dimension clearly. To add a section view, click the Cutting Line button, draw your cut line across an existing view, and SolidWorks projects the cross-section with automatic hatching. Detail Views zoom in on a specific region of a view — typically used for small features, thread reliefs, or tolerance-critical geometry where 1:1 scale doesn't give enough resolution for clear dimensioning. The Broken-Out Section view removes a portion of the part to show internal features in context — especially useful for assemblies where you want to show how a shaft sits in a bearing housing without creating a full section that hides other features.

Drawing View Type	When to Use	SolidWorks Command	Key Setting
Orthographic Views	Every drawing — shows front, top, side	Insert → Drawing View → Model	First vs. Third Angle projection
Section View	Expose internal bores, grooves, walls	Drawing View → Section	Cutting line direction
Detail View	Zoom in on small or critical features	Drawing View → Detail	Scale factor (e.g. 4:1)
Auxiliary View	True shape of angled or inclined faces	Drawing View → Auxiliary	Reference edge selection
Broken-Out Section	Show internal features in context	Insert → Drawing View → Broken-out	Spline boundary depth

GD&T Annotations: Tolerances, Datums and Surface Finish in SolidWorks

GD&T is the language of precision manufacturing — it defines not just what size something should be but how straight, flat, round, perpendicular, or true-positionally accurate it needs to be. In SolidWorks drawings, you add GD&T through the Annotation tab: Geometric Tolerance inserts feature control frames (the boxes with symbols and tolerance values), while Datum Feature creates the reference datum identifiers (A, B, C triangles). The most common tolerances you'll encounter at Pune manufacturers: flatness (how flat a mating surface must be for a reliable seal), perpendicularity (how square a bore is to a datum face), true position (how accurately a bolt-hole pattern is located), and runout (how much a rotating feature wobbles relative to its axis). For surface finish, SolidWorks uses the Surface Texture annotation — you specify the Ra value (roughness average) and the machining symbol (triangle with a bar for lay direction). Ra 3.2 μm is standard machined, Ra 1.6 μm is fine-turned or ground, Ra 0.8 μm is precision-ground for sealing faces. At Bajaj Auto Akurdi (164+ vacancies, Pune 411035), Bosch Pune (Adugodi Plant), and Mahindra Tech (Chakan), hiring managers consistently test drawing interpretation in technical interviews — they hand you an annotated drawing and ask you to explain the GD&T requirements out loud.

Bill of Materials, Balloons and Drawing Templates for Industry Use

In a SolidWorks Assembly drawing, the Bill of Materials is generated automatically from the assembly's component structure. Insert → Tables → Bill of Materials drops a table onto the sheet listing every part with its item number, quantity, description, and any custom properties you've defined in the part files. Balloons (Insert → Annotations → Balloon) draw numbered circles on the assembly view pointing to each component, cross-referenced to the BOM item numbers. The good news is that if your part files have properly filled Part Number and Description custom properties, the BOM auto-populates with zero manual entry — and any ECO (engineering change order) that renames a part updates the BOM instantly. Drawing Templates store your company's title block, standard notes, dimension styles, and sheet format so every drawing you generate matches the company standard without setup. Most Pune manufacturers provide a standard DWT or DRWDOT template to new hires — at Tata Technologies (Hinjewadi, Pune 411057), KPIT (Bavdhan), and Mercedes-Benz India R&D (Pune 411028), onboarding includes a half-day session on using the company drawing template. Freshers who already know how to import and use custom templates save significant ramp-up time. According to PayScale and AmbitionBox 2025–26, mechanical design engineers with strong drawing and GD&T skills in Pune earn ₹3.8–6.2 LPA at entry level versus ₹2.5–3.2 LPA for pure modeling roles.

Maharashtra's CMYKPY (Chief Minister Yuva Karya Prashikshan Yojana) provides ₹6,000–10,000 per month while you complete approved industrial training. If you enrol in ABC Trainings' SolidWorks or AI Powered Product Design program, you can apply for CMYKPY at the same time — offsetting your training fees with a government stipend. Multiple students from our Pune Hadapsar and Wagholi batches have done this successfully in 2025–26. The scheme is open to Maharashtra residents under 45 and aligns with PMKVY 4.0 frameworks.

FAQs

What is the difference between First Angle and Third Angle projection in SolidWorks drawings?

First Angle (ISO/European standard) places the view of a face on the opposite side of the projection plane — common in India, Europe, and global OEMs like L&T and Mahindra. Third Angle (ASME/American standard) places the view on the same side as the face — used in American companies and some Japanese OEMs like Toyota Kirloskar. SolidWorks lets you switch between them in Document Properties → Detailing → Projection type.

How do I add GD&T feature control frames in a SolidWorks drawing?

Go to the Annotation tab in the Drawing environment, click Geometric Tolerance, and the Property Manager opens. Select the GD&T symbol (flatness, perpendicularity, true position, etc.) from the symbol library, enter your tolerance value, specify the datum reference if required, and place the feature control frame on the drawing. Use Smart Dimension and Datum Feature annotations from the same tab to add dimensions and datum identifiers.

Can the SolidWorks BOM update automatically when the assembly changes?

Yes — SolidWorks BOM tables are parametrically linked to the assembly model. If you add or remove components, change part numbers in custom properties, or update quantities, right-click the BOM table and choose Update to refresh it. If you have "Keep Missing Items" enabled, removed parts will remain grayed out in the BOM so the change history is visible.

Do manufacturing companies in Pune test SolidWorks drawing skills in interviews?

Absolutely. At Bajaj Auto, Tata Technologies, KPIT, and most Pune-area tier-1 suppliers, technical interviews for Design Engineer roles include a drawing interpretation test — you're given an annotated drawing and asked to explain dimensions, tolerances, GD&T symbols, and surface finish requirements. Companies like Mahindra Tech and Bosch Pune go further and ask candidates to generate a drawing from a provided 3D model during the interview itself.
