How do I make my spline thicker in AutoCAD?

Use command ‘Pedit’ (polyline editing tools) and convert each spline to a Polyline, to which you can set a width (global width).

What is extrusion Modelling?

In Extrusion Modelling, the modeller starts with a single object, for example a cube, and simply extrudes the object to a point where they can make out the shape that they want. … Extrusion Modelling is good for making basic objects but lacks the ability to create the more complex models.

What is spline command?

The spline command in AutoCAD is used to create a smooth curve, which passes through a set of predefined points. It creates a non-uniform curve passing through the points.

What is the difference between spline and polyline?

Oh, well a spline is a continuous curve that passes through discreet points specified by the user. A polyline is a chain of points with line or arc segments linked end to end. … Splines are mathematically generated on regen in AutoCAD so they’ll always be smooth. This makes them suitable for machining toolpaths.

What is the use of spline in AutoCAD?

Creates a smooth curve that passes through or near a set of fit points, or that is defined by the vertices in a control frame. SPLINE creates curves called nonuniform rational B-splines (NURBS), referred to as splines for simplicity. Splines are defined either with fit points, or with control vertices.
