WHAT'S NEW IN CREO PARAMETRIC 3.0
Fundamentals (nguyên tắc cơ bản): A central or primary rule or principle on which something is based.
3D Printing is Available: Click File —» Print —» 3D Print to print parts and assemblies that were created in Creo Parametric using STL (stereolithography) files as an input to the software of the 3D printer. Most 3D printers use STL files as input. With the user-defined printer you can prepare your model for printing as described in the list below.
PTC Mathcad Prime is integrated (kết hợp cái gì đó để nó hoàn toàn trở thành một bộ phận của một cái khác; hợp nhất; hoà nhập) with Creo Parametric: You can use the embedded (gắn vào) worksheet as a scratch pad to record design notes, to solve simple to complex calculations, and as the mathematical source for parameters in the model. This makes it easier and faster to document engineering knowledge and design intent inside the model and is a powerful way to link the two together. You can use the embedded PTC Mathcad worksheet to derive (tìm thấy...từ) design parameters to use in Creo Parametric or to analyze (phân tích) dimensions from your model using the extensive array of mathematical tools in PTC Mathcad.
Improvements in Mass Properties are physical attributes of a mechanical part that relate to how the component will behave in an environment. These properties include familiar attributes such as the weight and volume of the object. They also include more advanced physical information such as its center of mass and moments of inertia.
View Normal Orientation: You can orient planar entities normal to the view direction —» Click View —» Saved Orientations —» View Normal to orient the model so that the selected planar reference, such as a surface, sketch, datum plane, or cross section, is normal to the view direction. If a second reference is selected, the model is oriented towards the top of the graphics area, as if the reference was selected as Reference 2 in the Orientation dialog box.
Reorienting the Model Is Easier:You can orient your model to be normal to a plane, planar surface, cylinder, linear edge, or three vertices —» Click View —» Named View —» View Normal (You can select a planar face, a cylindrical face, or a conical face and choose to orient the model normal to that reference).
Customizing Shortcut Menus: You can remove and reorder commands in shortcut menus. This increases productivity by having easy access to the commands you use most frequently and by removing the commands you do not use —» click File —» Options —»Shortcut Menu (Shortcut menus are also modernized to improve usability).
CREO 3.0 DESIGN EXPLORATION
Design Exploration Is Available: You can use Design Exploration to explore changes to a design without committing (cam kết) to the change —» click File —» Manage Session —» Design Exploration session —» Start/Open. Changing a product design and exploring new ideas is a technical challenge, especially when developing complex systems with many interdependent components. Typically, this process involves manual backup of models to folders, repeatedly closing and cleaning the Creo Parametric session, and manually revisiting and reviewing massive iterations (làm lại, làm đi làm lại; lặp đi lặp lại) until making a decision. Design Exploration helps to streamline (hợp lý hoá) the process of evaluating (định giá; đánh giá) new designs and deciding on changes to the design. In Creo Parametric, open a model. To start exploring new ideas —» click File —» Manage Session —» Design Exploration session —» Start to open a Design Exploration session and then in the Name box, type a name for the session.
This is where all your exploration ideas are stored. A snapshot of your Creo Parametric session content is saved to the checkpoint Pre-modified. You can now start to experiment with your design without risking the original models. As you make changes, you can add checkpoints. Each checkpoint stores only the incremental model changes since the last checkpoint. For your additional clarification, you can provide a checkpoint name, comments, and also define keywords to use, for example, in a search for the checkpoint at a later time. You can switch between checkpoints without losing information. In your Design Exploration session, multiple model iterations are replaced as they are captured in the active checkpoint. That eliminates the need to manually backup models to different locations or clean up your session each time you want to switch between different design iterations.
When manipulating models in an active checkpoint that already has successors, you can create new checkpoint sequences and form different branches. With branching, you can develop and evaluate multiple ideas, simultaneously. Every branch represents a different direction of the design. If some checkpoints along the branch are no longer needed you can delete them without losing information in a later iteration (repetition of a mathematical or computational procedure applied to the result of a previous application, typically as a means of obtaining successively closer approximations to the solution of a problem). If you shorten the branch, iterations from a deleted checkpoint are merged into its successor.
You can also delete a complete branch. You can navigate the Checkpoint Tree in Tree view, or in Timeline view. Checkpoints along the active path appear in a darker font making it easier to locate earlier checkpoints in same sequence. You can browse different branches that appear in a lighter grey font. When you are ready to make a decision, you can accept the checkpoint with the chosen design and then return to the Creo Parametric session. You can keep entire session data in the specified .TMZ file. All model iterations along the path to this checkpoint will be applied to the models from which you started the Design Exploration session.
Storing Changes in Design Exploration: Others can review your proposed changes. If you want your design reviewed by others, you can distribute the .TMZ file containing your design. Others can then explore your ideas or add their own. By default, Design Exploration stores only incremental changes. The first Pre-modified checkpoint stores only the paths to the locations of the starting models. If you plan to send session data to a user that does not have access to same the file system or to the locations of the original models, you can have all the start models added into the .TMZ file. The content of the .TMZ file is encrypted and compressed to avoid confusing the experimental design with the actual design.
CREO 3.0 PART MODELING & FLEXIBLE MODELING
Creo Flexible Modeling: You can untrim surfaces for native or imported geometry —» select a surface to copy and then click Model —» Copy —» Click Model —» Paste —» and then right-click to select Untrim to envelope or Untrim to domain (phạm vi; lĩnh vực) of definition (xác định, định nghĩa).
When copying a surface or quilt (khâu... vào giữa hai lần áo) you can use new options to untrim the geometry to its original definition or to the envelope of its definition. Surfaces can be untrimmed from both imported and native geometry. To untrim a surface, copy and paste the surface and then under Options in SURFACE: Copy either untrim to an envelope of the selected surface or untrim to the original domain of the surface. This creates an untrimmed dependent copy of the surface. In addition to untrimming a single surface, you can also untrim an entire quilt into individual surfaces. You can untrim the quilt to an envelope or to the original domain and create untrimmed surfaces for each patch in the surface.
Enhancements (sự làm thêm, tăng) to the Collapse Feature: You can collapse any set of consecutive (tiếp liền nhau) or geometrically-related features from Creo Parametric or Creo Direct —» click Model —» Editing —» Collapse (If all geometrically-related features are selected, the resulting feature is an Independent Geometry feature). If a set of consecutive features is selected, the resulting feature is an Incremental Geometry feature. If the first feature is an import feature, the other features are collapsed into that import feature. Intent references are maintained and you have the option to keep Analysis, Annotation, Publish Geometry, and Cosmetic features.
Chordal Rounds: You can create a chordal (A chord of a circle is a straight line segment whose endpoints both lie on the circle. A secant line, or just secant, is the infinite line extension of a chord. More generally, a chord is a line segment joining two points on any curve, for instance an ellipse. A chord that passes through a circle's center point is the circle's diameter. Every diameter is a chord, but not every chord is a diameter) or constant-width round —» click Model —» Round (in the Round tab —» click Sets —» Chordal).
Reorder Is Enhanced: Reorder functionality supports more flexible workflows —» click Model —» Operations —» Reorder. Use the Feature Reorder dialog box for more flexible workflows when reordering features. You can still drag and drop features in the Model Tree, however, the Feature Reorder dialog box gives you more visibility into how reordering will impact other features. For example, if you move Extrude 2 after Round 4 you can see that the features depending on Extrude 2 are moved along with it. You can also reorder to and from groups and move nonsequential features.
Read Only Features Are Easy to Identify: Features set to Read Only are easy to identify in the Model Tree —» click Model —» Operations —» Read Only —» Set all as read only and all the features are grouped together in the Model Tree. A lock icon appears next to Read Only Features. You can expand the Read Only Features but cannot modify the feature or references. In the Graphics window, you can see the dimensions for the feature, but cannot edit the dimensions. If you select Set as last read only, features from the beginning of the Model tree to the feature you select are set to Read Only Features.
Boundary Blend Enhancements: Resulting surface and connection quality is improved for Boundary Blend —» click Model —» Boundary Blend. Boundary Blend is significantly improved, resulting in smoother surfaces and connections. Resulting surfaces are degree 5. A new Optimize option is added to further improve the quality of a single surface with 4 boundaries. This optimizes the connection influence throughout the surface and produces a smoother surface, especially in the corners.
Flatten Quilt Enhancement: You can flatten complex, freeform geometry —» click Model —» Surfaces —» Flatten Quilt. The Flatten Quilt feature is enhanced to handle more complicated geometric scenarios (viễn tưởng) where the quilt to flatten is not rectangular in shape. There is also support for symmetry.
Chamfer Support in Creo Flexible Modeling: Chamfers are supported in Creo Flexible Modeling with the tools to recognize chamfers and edit chamfers and with functionality to remove and recreate chamfers during Flexible Modeling operations —» click Flexible Modeling —» Rounds/Chamfers —» Recognize Chamfers or click Flexible Modeling —» Edit Chamfer.
Enhanced Rounds Support in Creo Flexible Modeling: Conic (hình nón) and curvature (độ cong) continuous rounds are supported in Creo Flexible Modeling, and you can choose not to treat round-like geometry as an engineering round —» click Flexible Modeling —» Edit Round or click Flexible Modeling —» Rounds/Chamfers —» When you click Edit Round the current characteristics of a round surface appear and you can remove the round, or change the type to Circular, Conic, C2 Continuous, D1 x D2 Conic, or D1 x D2 C2.
Tangency Propagation (phổ biến, truyền bá) and Control in Creo Flexible Modeling: You can maintain tangent (đường tiếp tuyến (đường thẳng chạm vào bên ngoài một đường cong mà không đi xuyên qua)) connections to adjacent (góc kề, gần kề) geometry when you make geometric modifications to selected geometry. Geometry that is selected for modification with a tool on the Flexible Modeling tab such as Move, Offset, or Modify Analytic may be connected with tangency to neighboring surfaces. If that is the case, you may want the neighboring surfaces to be adjusted along with the primary surface to maintain that tangent connection —» click Flexible Modeling —» and then in the Move, Offset, or Modify Analytic tool, click the icon "Keep existing tangency to surface directly..."
Pattern Propagation in Creo Flexible Modeling: Propagating changes from one pattern member to all other pattern members is more flexible. Geometric changes made to any pattern member with tools on the Flexible Modeling tab such as Move, Offset, Modify Analytic, Edit Round, and Edit Chamfer, can be propagated out to all other members of the pattern. Make your geometric edits where they make the most sense to you and then easily propagate the changes to other pattern members —» click Flexible Modeling —» and then in the tab for the Move, Offset, Modify Analytic, Edit Round, or Edit Chanfer tool, —» click Options.
New Flexible Pattern Tool in Creo Flexible Modeling: Use Flexible Patttern tool to create Directiton, Axis, Fill, Table, Curve, and Point. To create a pattern, user select references to define the pattern leader, and select a pattern type to determine how the pattern instances are created. Pattern creation methods vary depending on the pattern type. For each pattern type, user define additional items such as a direction, an area to fill, an axis, placement points, or a sketch. User can define the spacing between pattern members, and the number of pattern members.
