AutoCAD · Dimensioning No matter how beautifully you draw something, a drawing without dimensions is just a picture. At the end of the day, machinists and vendors only care about the numbers — and trust me, missing a single dimension is all it takes to get a phone call you didn’t want. On the flip […]
Machine Design · Fasteners Bolts are one of the most fundamental elements in mechanical design — yet in practice, they are surprisingly easy to get wrong. With dozens of variations in head shape, thread form, and material, selecting the right bolt for the job is a skill that separates a careful engineer from a careless
AutoCAD · Text Input A CAD drawing is more than just dimension numbers. Part names, material callouts, notes, machining instructions — there are more situations that require text than you might expect. And text input in AutoCAD is not as simple as a word processor. There is quite a bit to learn: the difference between
AutoCAD · Layers As you work on drawings in AutoCAD, outlines, centerlines, dimension lines, hatches, and all sorts of objects pile up, making the drawing increasingly complex. If you don’t organize them into layers from the start, one small edit can cause a chain reaction of problems. “I drew everything on Layer 0 without any
AutoCAD · Object Editing Drawing basic shapes in AutoCAD isn’t that difficult. The real challenge comes after. Editing tasks — trimming and extending lines, rounding corners, copying, and rotating objects — make up the majority of actual drafting time. “From TRIM (TR) to ARRAY (AR) — here’s a complete guide to the object editing commands
Mechanical Engineering · Fluid Power When designing body jigs or automation equipment, there’s always a moment when you need to select a pneumatic or hydraulic cylinder to lift heavy parts or perform clamping operations. “If I supply 4 bar of air into a 50mm bore cylinder, how many kg of force can it push?” If
NAS · File Sharing · Real-World Setup What happens when you delete a file from a Windows network shared folder? Unlike a local drive, the file is permanently deleted immediately — no Recycle Bin involved. In a team environment where multiple people work on the same files, this can be a serious problem. “It was
AutoCAD · LISP In mechanical design, a surprisingly large amount of time gets wasted on drawing cleanup. This is especially true when working with drawings received from other companies, or assembly drawings that have been revised many times — overlapping lines bloat the file size and cause issues like failed hatching. “Why is this drawing
Tips · Windows If you try to run gpedit.msc (Local Group Policy Editor) and get the error “Windows cannot find gpedit.msc”, it’s because your PC is running Windows Home edition.
