Quick Surface is a powerful option for Verisurf Reverse that efficiently creates smooth, high-quality surfaces from meshes derived from scan data or STL files. Quick Surface maintains curvature continuity between adjacent surfaces and is ideal for creating smooth, high-speed toolpaths.


Can this process even be multi-threaded (aside from your multiple 3dm idea) since you would need to re-use the surface after each cut? Seems you need to do either all at once (as it is now, not multi threaded because the circles need to know about eachother) or one at a time but by reusing the surface from the previous cut.

While more folks than ever before are accustomed to working with mesh-based data, the ability to take a point cloud derived mesh and turn it into useful surfaces for use in a CAD system still remains the preserve of costly specialist software from the likes of 3D Systems (with its Geomagic Design X and Wrap systems) and Innovmetric (with Polyworks).


Recognising the market potential for a standalone version of this, Kostadin began development on QuickSurface in the last few years and the first release is out now. The overarching goal of QuickSurface is to provide a set of tools that allow you to take a mesh-based file, typically from a 3D scanner, and turn it into a set of surfaces that can be reused downstream in any CAD system.


For example, it might be that you have a polygon mesh of a scanned part and just need to be able to extract a few key surfaces in order to build mating parts or to take measurements from or work up the remainder of the part.


The last option (and probably the most useful) comes in the form of manual freeform patching tools. Essentially, QuickSurface allows you to sketch in a surface patch layout (using four-sided or quad surfaces) that snaps control points to the surface of your mesh.


Alongside these raw geometry modelling tools, there are also a number of editing tools to help tidy up and build additional features. For example, a number of the operations have symmetry controls built in, so you can define a plane and have the system build a mirror of your surface patches.


When I draw a line to close the perimeter and the face is automatically generated, but al the studs are visible through the face. I know that I can build out from the wall to resolve, but is there a quicker way as I have a large number of walls and angles which would make it a very large task.


I have also considered drawing a 1" line out from each corner on in order to create the raised surface. This is a solution, but hoping for a simpler one because I would still have a tremendous amount of work due to all of the angled surface on the roofline, etc.






Since this particular model is in such a late stage, I have determined that my quickest solution is to select ALL framing members in just a couple grabs, make it a group, then build faces outside of that group. This allows me to give the material some thickness without bleed-through. So far, it is working well and I am making each surface as a group or component, respectively.


Digitized Shape Editor (DSE) and Quick Surface Reconstruction (QSR) are the main workbenches in CATIA for dealing with scanned and point cloud data. DSE is used to import the scan and improve its quality, ultimately generating a mesh. QSR takes this mesh and converts it to surface data that can be used in other CATIA workbenches, such as Generative Shape Design or Part Design, as the basis of a new part.


Quite often, the point clouds are very dense and contain more data than needed. Use commands such as Filter () and Remove () to reduce the number of points. This will help with general performance and can also lead to smoother, cleaner surfaces, especially when dealing with rough or less-than-ideal scans.


After creating the mesh, head to the Quick Surface Reconstruction workbench. The Automatic Surface () tool can be used to quickly generate a surface that matches the meshed shape from DSE. Depending on the end goal, this may be enough to get a usable surface. Other options include PowerFit (), used to adapt to surfaces within curves, or Basic Shapes

(), used to generate primitives such planes and cones around certain areas of the mesh to get more robust features. Curve and Surface Networks can be used to generate surfaces akin to a Multi-Section.


Alternatively, it may be easier to skip creating surfaces directly and instead, trace characteristic curves on the mesh with 3D Curves (). Then, using Generative Shape Design, create a high-quality CATIA surface from these curves.


In the image above, the top of the part primarily consisted of flat faces, which were built using Basic Shapes, ensuring the faces are completely flat, planar, and high-quality. The gear portion at the bottom of the part was converted to a surface with Automatic Surface.


Once the QSR surfaces have been created, these can be used in any of the standard CATIA part workbenches. You may need to Split/Trim/Fillet these individual surfaces to get a finalized shape. Above, the Basic Shapes were filleted and trimmed, then Joined with the Automatic Surfaces to create the final model skin.


For this one, a solid was generated from the joined surface in the prior step. From here, any standard Part Design commands, such as Pad, Pocket, Hole, Chamfer, etc. could be used to modify, tweak, update or otherwise redesign this part.


Please go ahead and submit the idea. I find it more of a nuisance when the surface region was present in an early generation of the model and causes all kind of errors and regeneration issues when you make an assembly cut at a later stage.


A long time ago (version 18 ish?) the work around to create a surface region on a component that then sees an assy cut was to open the part and create the region in part mode. The region (or partial region) was then available in assy mode. I am sure I got this gem of wisdom when I was at PTC, a methodology document written by a Mechanica Consultant other than myself.


The AMI Chemi family of instruments combines a variety of temperature-programmed techniques, including: temperature-programmed desorption (TPD), temperature-programmed oxidation (TPO), temperature-programmed reduction (TPR), and temperature-programmed reaction (TPRx). The AMI Chemi family of instruments can also perform pulse chemisorption, dynamic BET, and gas-phase iso-thermal reaction experiments. The AMI family includes high-pressure instruments with the AMI-300HP; sulfur resistant models with the AMI-300S, kinetic determining instrumentation with the AMI-300 SSITKA, and the new AMI-300ir for direct determination of adsorption/desorption surface process.


The AMI Physi family of instruments combines a variety of dynamic and static techniques for surface area, pore size distribution, and pore volume determination. The AMI-surface DX is a fully automated high-throughput (4 station) Dynamic BET analyzer that uses the absorption peak for highly accurate results. The AMI-meso series of instruments employ the static volumetric method for surface characterization of meso-porous materials. The AMI-micro series of instruments employ the static volumetric method for the determination of surface properties for meso-, micro-, and nano-porous materials.


Quick series gas adsorption analyzer continues the many advantages of TOP, compact body, very small dead volume, stable vacuum, excellent cold bath liquid surface constant technology, is the best choice for research and development, quality control.


QUICK series instruments perform better in the scene of rapid detection of large quantities of samples. The instrument mainly detects the specific surface area of the sample and the pore size distribution over 2 nm. It can also detect the adsorption capacity of the sample to specific gases. The instrument is designed with a four-station common Dewar bottle to ensure no error in parallel tests and more stable test results


In this work we investigate the extent and magnitude to which viscous dripping of the lithospheric root and subsequent mantle uprising controls the plateau uplift in the Peruvian section of the Central Andes using numerical geodynamic experiments. Model predictions satisfactorily explain the nearly axisymmetric pattern of surface uplift with higher surface elevation of the Western and Eastern cordilleras and relatively lower elevation in the Altiplano associated with thicker crust and high seismic wave speed sub-Moho anomaly interpreted from seismic tomography model18. Our results have implications for understanding the role of lithospheric drips that presumably control the rapid surface uplift (10 and 6 Ma) in Bolivian Altiplano37, as well as Miocene Arizaro basin in Puna Plateau41 and other parts of the Andean orogenic system.


Overall, the results of this work suggest that lithospheric drips and induced crustal flow can explain enigmatic cause of rapid topographic uplift, basin formation, and the paradoxic relationship between the relatively thicker crust underlain by lower surface topography in central Andes and that lithospheric drips play a pivotal role in the evolution of Cordilleran orogenic cycle39.


Numerical calculations are carried out by the SOPALE numerical software that uses arbitrary Lagrangian-Eularian finite element techniques to solve for the plane strain deformation of complex viscoplastic behavior of materials75. This technique is useful for treating finite deformations, and for tracking boundaries such as free surface and motion of internal particles at any depth and readers are referred to following studies for further explanations on how numerical (governing equations) calculations are conducted52,75,76,77.
