Geometry
Geometry serves as the foundation for the majority of finite element meshes. Hence, it is crucial to possess reliable tools for generating geometry.
SDC Verifier has the capability to construct geometry ranging from simple points to intricate 3-D solids. In essence, users can create, duplicate, or modify geometry.
Points
Points are used for constructing other geometry or finite element data.
- Uses the coordinate definition dialog boxes to create points.
Text
- Utilized for specifying text to annotate your model, which will be presented in the view.
Curve
Curves serve as the foundation for creating surfaces and can also be derived from surfaces.
These curves use reference points to establish their location. You can directly apply loads and constraints to curves, and they will be automatically converted into nodal/elemental values on the associated FEA entities.
Line
Project Points... - create a line between two locations.
At Angle... - create a line from specified base coordinates at a specified angle from the workplane X axis.
Angle to Curve... - create a line from specified base coordinates at a specified angle from the direction of specified curve.
Point and Tangent... - creates a line in the workplane through a point and tangent to a selected arc or circle.
Tangent... - creates a line in the workplane which is tangent to two arcs or circles.
Continuous... - creates a series of connected line segments between locations specified in three-dimensional space.

Arc
Radius-Start-End... - creates an arc in the workplane by specifying two end points and the desired radius.
You have the flexibility to define any three-dimensional locations, yet they will be projected onto the workplane along its normal direction.

Circle
Radius... - creates a circle by defining the two endpoints of a radius, specifically, a point at the center and another on the circumference.

Tangent to Curves... - creates a circle of a specified radius in the workplane which is tangent to two other curves.

Spline
Project Control Points... - creates a spline in the workplane by the location of the control points. Specifying 4 points Bezier spline will be created, more points will force the curve to be a B-spline.
Project Points... - creates a spline in the workplane by the location of the points that spline passes through. The control points calculates automatically.
Specifying 4 points Bezier spline will be created, more points will force the curve to be a B-spline.
