Parametric Modelling, step by step
Feature order is design intent, written down where the software can read it.
- Sketch on a datum planeNot on a model face. Faces move; datum planes do not.
- Fully constrain the sketchNo dragging. An under-defined sketch moves when a size changes.
- Build features in orderBase feature, then what depends on it, then the cosmetic work.
- Name key dimensionsDrive related sizes from one parameter or an equation.
- Test the modelChange the driving dimensions and check nothing breaks or flips.
A model that only its author can edit is unfinished work, however good the geometry looks.

- Who is the Parametric Modelling poster for?
- Parametric Modelling belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning cad & drawing can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Parametric Modelling poster?
- Any model that will be revised, reused, or handed on to another engineer. A wall chart earns its place by being glanceable from where the work is happening, so Parametric Modelling belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Parametric Modelling?
- Assembly Drawings, Auxiliary & Detail Views and Choosing Views sit alongside Parametric Modelling in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Assembly DrawingsAuxiliary & Detail ViewsChoosing Views
- Is the Parametric Modelling poster free to download and print?
- Yes. Parametric Modelling downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Parametric Modelling poster print at?
- Parametric Modelling is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Parametric Modelling loses nothing.Printing guide
