Quick Start Guide

Welcome to the rapidformXOR quick start guide. rapidformXO Redesign is the first software solution that allows users to go from 3D scan data to a fully parametric CAD model. While traditional 3D scan data processing software has focused solely on improving the tools for optimizing polygon mesh models or generating high quality NURBS surfaces from 3D scan data, the needs of those who require parametric CAD models from 3D scan data have been largely ignored.

rapidformXO Redesign addresses the limitations of existing 3D scan data processing software by complementing its mesh modeling and NURBS surfacing capabilities with newly developed CAD modeling capabilities, providing users with the tools to go from 3D scan data to a parametric CAD model. The combination of these capabilities enables users to create parametric CAD models that contain both prismatic and freeform features.

Terminology in rapidformXOR

Model	A single document made up of mesh or features.
Feature	Individual shapes and geometric elements that construct a model.
Mesh	triangulated scan data or FEM mesh data that contains poly-face, poly-vertex, poly-edge or boundary.
Region Group	A group or region made up of poly-faces. Regions assist in alignment of the mesh data to the global coordinate system and in the selection of a region of interest for extracting the design intent and converting it to a surface.
Solid Body	A B-rep entity that has both geometry and topology information.
Surface Body	A zero thickness 3D entity with edge boundaries.
Sketch	A set of 2D objects (line, rectangle, circle, arc, ellipse, spline, etc) on a plane, a face or a planar cross-section of the mesh.
3D Sketch	A set of 3D curves in space or on mesh faces.
Ref. Geometry	A geometry used to assist in creating features Redesign Assistant™ for design intent extraction -Ref. Point: extraction, circle/sphere center, projection, intersection -Ref. Vector: extraction, cylinder/cone axis, revolving/extrusion axis, Intersection -Ref. Plane: extraction, projection, offset, rotation, tangent, orthogonal, mirror -Ref. Polyline: intersection, projection, silhouette, fillet, sweep, bead line, pipe, parting line, boundary, revolving/extrusion profile -Ref. Coordinate: extraction, intersection, tangent

Mode

There are six modes in rapidformXOR. Each mode creates or edits its own entities. The following image shows each mode.

Mesh		In the Mesh Mode, you can heal incomplete mesh data using Heal Wizard, Fix Normal, Fill Holes and so on. You also can edit boundary, regenerate triangles for FEM, RP or Machining. rapidformXOR supports more functions to create complete mesh data.
Region Group		In the Region Group Mode, you can divide region that is grouped by analyzing the surface of mesh data. These regions are used for creating surface, reference geometries and so on.
Mesh Sketch		In the Mesh Sketch Mode, you can extract section information and create sketch from segments of mesh data. These sketches are used for creating solid or surface body.
Sketch		In the Sketch Mode, you can draw line, arc, curve, fillet and etc without mesh data. You can use Sketch such as other CAD modeling software.
3D Mesh Sketch		In the 3D Mesh Sketch Mode, you can draw 3D spline on the mesh or extract section curves from mesh. These curves can be used to create surface or solid body.
3D Sketch		In the 3D Sketch Mode, you can draw 3D splin in the space, extract section from body or create intersection curve between entities. These curves can be used to create surface or solid body.

Examples

The purpose of this quick start guide is to give you a “quick start” understanding of the modeling process in rapidfomXOR. By working through the tutorial procedures, you will learn the fundamentals of rapidformXOR.

Mesh Editing

Healing mesh irregularities and performing a series of mesh optimizations to the imported 3D mesh

CAD Modeling without Mesh Data
