The limit is removed once you upgrade to the commercial version, Creo Elements/Direct Modeling. There is, however, a limit to the number of parts you can work with in assembly-it’s 60. For quick concepts in 3D, or quickly reshaping imported 3D CAD data through a neutral file format, CE/Direct Modeling Express offers more than enough functions-far more than what you could rightfully expect from a free program. It’s not as refined as ray-traced rendering, but it’s sufficient to give you a good idea of the finished product’s aesthetic appeal.ĬE/Direct Modeling Express and its predecessor Creo Sketch serve as proof of PTC’s plan to drastically reform its CAD and PLM strategy, shifting from an all-inclusive package to a series of standalone modules. So if you want to work on a SolidWorks, Inventor, or Solid Edge file, you’ll have to convert it from its native format to a neutral format (IGES, STEP).ĬE/Direct Modeling Express has Realism Enhancement options for you to activate ground reflections, shadows, background colors, and rendered surfaces. The software’s present import, or 3D reading, is limited to neutral formats mostly. It’s a lot easier to design interlocking parts (for instance, creating a shaft that must fit into a hole in an existing part) when you don’t need to launch a new modeling window to create a new part. You can, for instance, create a new part within the assembly environment by sketching a profile on a new work plane and extruding it into a solid. The software makes little or no distinction between the two.
In CE/Direct Modeling Express, part modeling and assembly modeling are just a tab away. The software is quite good at guessing your desired constraints, so if you push lines and arcs around in 2D, you’ll find nearby segments reshaping according to how you’re moving the geometry. The software allows you to push, pull, rotate, and move faces and features with little or no concerns for feature history or parametric history-a freedom that’s ideal for exploring design concepts before committing to production or manufacturing.ĬE/Direct Modeling Express’s flexible modeling approach is not just for 3D modeling it extends to 2D sketching as well. You may think of CE/Direct Modeling Express as a trimmed down version of CoCreate, derived from the same underlying technology. CoCreate’s Copilot (the control arrows for moving and rotating features) greets you from its new home, CE/Direct Modeling Express.
If you’ve seen or used Co/Create, PTC’s push-pull CAD modeler, you’ll find yourself in semi-familiar territory. This week, PTC comes out swinging again, with a free direct editing application called Creo Elements/Direct Modeling Express (CE/Direct Modeling Express).
A few weeks ago, we got the first glimpse of a PTC Creo app, in the form of a free paint and draw program called Creo Sketch.
