What's frustrating about errors in Autodesk Inventor
Read moreA cross-reference table mapping AutoCAD's commercial versions to their release number, .NET version, DWG/DXF format and internal code name — with, for each column, what it actually means.
Read moreHow to join segments, arcs, and NURBS end to end to form contours and polylines.
Read moreSixth article in the series: we define the ICurve2d and IBoundedCurve2d interfaces to model parametric curves, from infinite lines to circular arcs.
Read moreHow to model intersection results between curves: crossings, tangencies, overlaps, and lazy computation of expensive information.
Read moreHow NURBS curves fit into our interface hierarchy: control points, knot vectors, evaluation, and trimming.
Read moreThird article in the series: we add +, -, * and / operators to our types so geometric code reads as naturally as mathematical formulas.
Read moreFirst article in a series about building a geometry library in C#. We start with the most fundamental type: the point.
Read moreFifth article in the series: we implement geometric transformations using homogeneous matrices, then explore a lighter alternative with quaternions.
Read moreFourth article in the series: we create a dedicated type for directions, which guarantees by construction that its length is always 1.
Read moreSecond article in the series: after the point, it's the vector's turn. Direction, length, dot product, perpendicularity… the foundations for working with directions in 2D and 3D.
Read moreA concrete case of the infamous E_FAIL: an .adsklib file that does exist on disk, yet which Inventor stubbornly refuses to open.
Read moreHow to determine if a point is inside a contour in AutoCAD.
