BricsCAD v21 offers many enhancements to 3D modeling tools to help simplify and automate the modeling process.
Dynamic UCS is now supported by the PLAN command. This allows you to select a face for the current UCS and immediately display it in plan view.
The new DMTHREAD command enables you to add a standard parametric thread to a cylindrical face of your 3D solid. You can edit the properties of the thread using the Mechanical Browser.
Drawing views created with the VIEWBASE, VIEWPROJ, OR VIEWSECTION commands represent the threads following drafting standards. The following image show views of a cylinder before and after adding threads.
The DMCHAMFER command offers more flexibility with new asymmetrical, angular, variable symmetrical, variable asymmetrical and variable angular modes.
The DMFILLET command offers more flexibility with a new variable radius mode.
The DMPUSHPULL command includes an option to specify subtract mode (on/off), which is also controlled by DMPUSHPULLSUBTRACT setting.
It also allows you to switch the starting point of the dynamic dimensions on cylindrical faces. Press the Tab key to switch between radial and offset dimensions.
The new VIEWBREAK command enables you to break an associative drawing view of your 3D model created with the VIEWBASE, VIEWPROJ, or VIEWSECTION commands and automatically include break symbols. You can change the appearance of a selected broken view symbol using the Properties panel. The VIEWBREAK command correctly supports dimensions you put on the drawing view before breaking. They remain associative with your 3D model and the drawing view.
3D Entity Snaps
Easily toggle 3D entity snaps on and off by pressing the F4 function key.
The vertices of 3D polylines now support sub-entity selection, the Properties panel, and nearest distance.
Additional enhancements to 3D Polylines enable you to apply 3D constraints to their vertices and edges.
The new PARAMETRICBLOCKIFY command enables you to quickly convert model entities to parametric blocks. Select a parametric block or parametrized entities as input geometry to compare against other geometry in the drawing. Matching geometry is automatically converted to parametric blocks.
Material glossiness has been adjusted to ensure entity details are distinguishable, even with glossy materials. The glossy effect is less intense for light materials and more intense for dark materials.
Solids and Meshes
Convert to Mesh
The CONVTOMESH command is optimized to triangulate planar faces only when necessary and with as few faces as possible. As an example, the original solids on the left are converted to meshes in BricsCAD v20 (center) and BricsCAD v21 (right).
Convert to Solid
The CONVTOSOLID command enables you to convert a mesh to an optimized 3D solid based on the new SMOOTHMESHCONVERT setting.
When set to optimized, coplanar and adjacent faces are merged into a single face. As an example, the original mesh on the left is converted to a solid in BricsCAD v20 (center) and BricsCAD v21 (right).
The Properties panel offers access to additional properties for selected mesh entities. Mesh entities now include Mesh and Geometry properties including the ability to specify smoothness.
The Properties panel also supports mesh sub-entities including faces, edges and vertices enabling you to apply different levels of creasing.
The new GENERATEASSOCATTRS setting controls generation of associative data on 3D solids during modeling. When set to On, 3D solids contain associative data from the moment of creation. This allows BIMSECTIONUPDATE and VIEWBASE commands to produce drawings for which dimensions and tags can be automatically updated after the 3D model changes.
The Twist option is added to the -VIEW command.
The Animation Editor is enhanced to support the animating of exploded views in model space.
Point cloud functionality is significantly faster and more powerful in BricsCAD v21.
The E57 file format is added to the supported files for pre-processing.
When you attach a point cloud that requires pre-processing, it converts 5 to 8 times faster in BricsCAD v21 than in v20. A progress meter at the bottom of the display shows the conversion progress.
The new POINTCLOUDALIGN command automatically rotates a point cloud to optimally align it with the X and Y axis. To determine the best alignment it can analyze the entire point cloud or you can specify the most relevant area.
The point cloud displays bubbles at all the scan locations. It’s at those locations where you will experience the most realistic visual representations.
Double-click one of the bubbles in model space to open the Bubble viewer. You can press the middle mouse button and move the mouse to view the point cloud in any direction from that scan location.
Press the Tab key to cycle between three different visual modes.
The first mode displays the points as their actual colors or in greyscale, depending how the data was scanned.
The second mode displays the points as red, green, or blue according to their normal vectors. The colors correspond to the UCS axes.
The third mode displays the points from light to dark as the distance from the scan location increases.
You can easily sync the drawing view to match the Bubble viewer by pressing Ctrl A.
The new Point Cloud Closest Point entity snap significantly improves your ability to select relevant point cloud points. It uses an imaginary cylinder from the current viewpoint toward the cursor.
The radius of the imaginary cylinder is defined by the Entity snap aperture box setting.
Enable the new Point Cloud Closest Point entity snap along with other 3D entity snaps in the Entity Snap menus, toolbar, and settings.
The new POINTCLOUDEXPORT command allows you to export a cropped selection of a point cloud to a .pts file.
