10 Why Concept Design with Creo? Scalable Choose your combination of solutions Interoperable Users can share the same model, while using the right tool for their role Leverage existing models to create new concepts Concepts can be analyzed early in the process, preventing re-modeling later on Time to Value No time wasted recreating concepts Explore more concepts in the same time, improve product quality Reduce Time to Market Less opportunity for errors in model creation 10

11 Creo Layout 11

12 2D Authoring Environment Unconstrained Easy Drafting Sketching Tools Familiar tools for geometry creation Toggle construction mode on and off Sketching Guides Snap geometry to important locations Horizontal, vertical, parallel, perpendicular, equal size, etc. Not a permanent constraint, just a placement guide Touch buffer Determines which entities to reference w/ guides Add / remove references in Idle mode Active geometry tool Geometry dragging Can be configured Number of references in guide queue How long it takes to touch a reference 12

13 2D Authoring Environment Reuse Data From 2D and 3D Models Import data from standard 2D formats DXF, IGES, DWG, DRW, MI, etc. Select which entities to import Import cross sections from the Creo Parametric App Part or assembly Create structure in Layout from the assembly components Preview the cross section on the solid model during import Import raster images using the trace sketch TIFF, JPEG, etc. 13

14 2D Authoring Environment Data Organization Public and Private data By default data is private (configurable) Private data is only visible within the concept design Designate data as Public when it should be available to 3D User Defined Tags Assign a Tag to any group of entities Structure Nodes Create, modify, and reorder product structure Automatically create structure groups from imported data or file Entities have unique membership in no more than one group 14

15 2D Authoring Environment 2D Detailing Use standard or custom drawing formats Create new designs with a format Swap formats as needed Set the concept scale Set the concept text size Dimension your designs Use dimensions as references or Drive geometry with them Graphic indication of growth direction Lock growth direction or entire dimension Type / placement options in RMB menu 15

16 2D Authoring Environment Navigation / Misc. Favorite Views Filmstrip Easily save a zoom level and location to each frame The frame contains a thumbnail of the saved view Recall these saved views at any time Give the views names and comments Drag to reorder the saved views Collapse the filmstrip to maximize screen area 16

17 Basic 3D Integration 2D Layouts in Assemblies Direct Assembly of Creo Layout Creo Layout files can be added to assemblies Layout file is a node in the model tree Acts as a special type of skeleton model Geometry tagged as Public will appear in 3D Curves, planes, axes, points, coordinate systems Use Layout as assembly reference for components 17

18 Basic 3D Integration Reference 2D geometry to create part features Copy Geometry or External Copy Geometry Select references from Layout file Associativity maintained to original Layout file Create Part Features Referencing Layout Geometry Build feature intent on top of 2D geometry Changes made in 2D Layout are reflected in 3D 18

19 Demo Agenda Create 3 concepts for a Cutting Tool Select one of them to add Dimensions Structure Make public Create a part based on the layout Add the layout to an assembly 19

21 Direct Modeling Questionnaire Direct modeling is een manier van 3D modelleren, waarbij de geometrie gecreeerd wordt op het oog i.p.v. op basis van dimensies PTC Creo Direct modellen hebben altijd een plaats in de ruimte o.b.v. coordinaten en dimensies en is dus volledig bepaald Geometrie creeeren op het oog kan echter ook omdat er geen nadruk gelegd wordt op het bematen van het model Direct modeling kan geen gebruik maken van bestaande geometrie van het eigen model of andere modellen Geometrie kan gebruikt worden, echter zal er geen afhankelijkheid gevormd worden Doordat Direct modeling geen referenties of vaste dimensie schema s gebruikt kan direct de wijziging doorgevoerd worden die je voor ogen hebt Juist, er hoeven geen relaties aangepast te worden. Ideaal dus voor concept design, waarbij wijzigingen in het model niet voorzien kunnen worden. 21
