In-Depth Information
Vertical
Forces a line or two points to be vertical relative to the current coordinate system
Tangent
Forces an object to be tangent to a selected arc or circle
Joins a selected spline object with another spline, line, arc, or polyline while maintain-
ing curvature (also known as G2) continuity
Smooth
Symmetric
Forces two objects, or two points on objects to be symmetrical about an imaginary line
Forces two lines or linear polyline segments to be the same length; forces two arcs or
circles to have the same radius
Equal
Text objects can also be geometrically constrained. You can apply horizontal
or vertical constraints to text, and you can make text parallel, perpendicular, or
collinear with lines. Anyone who's had to label utility lines on civil engineering
drawings in earlier releases so the text aligns with the linework (who. . .
moi??
)
will be very happy with this feature!
Applying a little more constraint
If you're using the full version of AutoCAD (not AutoCAD LT), you can constrain drawing
objects geometrically by clicking buttons on the Geometric panel of the Parametric tab.
In the following steps, I show you how to get started with geometric constraints.
You can ind the iles I use in this sequence of steps at this topic's companion
The drawing named
afd19c.dwg
contains the unconstrained geometry, and
drawing
afd19d.dwg
contains the end product.
