New in 3D Solid Modeling

The 3D History now displays the results of the new command of the Mechanica module – Flanging.

A possibility to change the construction order in the 3D history tree has been implemented, an element of the end of the 3D construction history has appeared. Now the history elements can be swapped if it does not destroy the model, as well as hide some of the elements (for example, to analyze the model).

In the Presspull (PRESSPULL) command now it has become possible to move part of a selected face.

The Extrude (EXTRUDE) command now takes into account internal closed contours (holes).

In the Presspull (PRESSPULL) and Extrude (EXTRUDE) commands, a possibility has been added to align 2 faces: one created using extrusion and one created on the model.

In the parametric modeling mode, it has become possible to create a model with a hole in the Stretching by sections mode.

A search bar has appeared in the Parameters Manager window.

Now you can edit the color of lines and text of dimensional constraints. Often, such constraints were very difficult to distinguish on the screen, especially when the grid was on. The DYNCONSTRAINTSCOLOR and DYNCONSTRAINTSTXTCOLOR system variables are responsible for these colors, and you can set the color in the Color > Dimensional constraints of the Options dialog.

 

In the following cases, the visual style is automatically set to Top SW Iso:

• When entering sketch editing mode (PSADD), if there are no 3D constructions in the docu-ment, and the view is oriented along one of the WCS axes;
• When entering the 3D block editing mode (3DBEDIT).

Also, in the 3D block editing mode (3DBEDIT), the display style is automatically set to Gouraud shaded with edges.

The program behavior has been fixed, when in the 3D block editing mode, after launching any 3D command or switching the 3D modeling, the ribbon each time switched to the 3D Block Editor tab.

The work of angular 3D constraint (3DANGLE) at large angles has been fixed. For this, when applying a 3D angular constraint, the user is given the opportunity to set the rotation axis so that it can be unambiguously determined how to measure angles of more than 180 degrees.

The bug due to which a crash occurred when trying to extrude a contour containing an ellipse or spline has been fixed.

An incorrect behavior of the Presspull (PRESSPULL) command when moving multiple faces has been fixed.

The bug due to which the angular constraint did not save the direction and could suddenly start counting in the other direction has been fixed.

The bug where it was not possible to create a 2D constraint to align a polyline vertex with a point has been fixed.

The bug due to which changes to hide 3D objects using isolation in files with 3D models were not saved has been fixed.

In the 3D Module command Convert to Solid (CONVTOSOLID), the error of converting a mesh to a solid, which occurs when the mesh was located at a large distance from the coordinate origin, has been fixed. In this case, the level of detail during the conversion turned out to be too low.

Blocks containing solid objects (3D solids) or parametric bodies is now edited in a separate editor, which is called by double-click on such a block with the 3DBEDIT command.

The 3D Block Editor context tab appears on the ribbon with additional tools for 3D editing, buttons for saving the result and exiting the editing mode. The tab lacks a number of commands that are present in the standard block editor, for example, for working with attributes. However, these commands can still be called from other ribbon tabs, menu, or command line.

If there is no license for the 3D module, editing 3D blocks using standard methods will still be available, but without the ability to use 3D editing commands.

In the drawing explorer, 3D blocks have been moved to a separate section.

The 3DREFEDIT command is used to edit references.

A new Section command of 3D-module in the 3D Tools ribbon tab of the Direct modeling section creates and object of Region type that represents a 2D cross section of 3D objects, including 3D solids, surfaces and meshes.

Previously, in order to create a drawing in a layout, it was necessary to create projections of 3D objects in model space and then insert them into layouts using viewports. An additional option has been implemented in the nanoCAD 22, using which you can create 2D views directly in layouts without duplicating them in the model space.

The mode of auto-applying constraints is implemented in parametric modeling, when building flat sketches of future models. Now you don't have to waste time creating geometric constraints - the system independently parameterizes the object.

nanoCAD can now design 3D parts from sheet metal. Here, for example, are parts typical of those that can be designed with the new sheet metal module:

Among the new commands are the following:

The basic tools (Sheet solid, Bend edge, Bend over segment, and Fold by sketch) create standard parts from sheet metal. Folds can be bent and unbent at any time, and corners are handled by a variety of reliefs and bends.

For specific sheet metal parts, there are the Shell and Ruled shell tools, plus additional tools quickly add commonly used sheet metal elements, such as these ones:

• Collars

• Holes

• Plates

• Shutters

• Stamps

• Stiffeners

• Undercuts

The Unbend tool makes flat drawings of 3D sheet metal parts.

Each release of nanoCAD adds new commands. To make it easier to focus on the design at hand, the primary 3D modeling commands are now grouped by mode in the Modeling Modes section of the 3D Tools ribbon:

• Parametric

• Direct

• Sheet 

• Meshes

When users switch between modeling types, the ribbon automatically changes the commands displayed to those specific to the selected modeling mode. For example, when a user selects Parametric modeling mode, the ribbon changes to show commands for creating 3D geometry based on parametric sketches.

When the user selects Direct modeling mode, the ribbon display commands for creating standard 3D models and operations related to direct modeling.

When the user selects Sheet metal mode, the commands are those useful for this mode, such as Sheet solid, Shell, and Unbend.

When the user selects Meshes modeling mode, the commands standard for creating 3D surfaces become available.

Commands that apply to all types of modeling such as, for example: Chamfers and Rounds, Boolean operations, commands of construction geometry, manipulation and others are always visible to a user.

nanoCAD makes it more convenient to work in sketch mode when using the ribbon interface. There no longer is a need to switch between tabs, as after launching 2D sketch mode, all tools necessary for creating parametric sketches are shown by the ribbon. The most frequently used commands are always at hand; there are no superfluous ones.

nanoCAD adds two more types of 3D constraints: 3D-tangency and 3D-symmetry. These are in addition to the 3D-insert, 3D-merge, and 3D-corner constraints from previous releases.

The 3D-tangency constraint joins surface tangents that are more complex than what the existing 3D-merge constraint can handle. It creates tangents between, for example, the following objects:

• Cylinders to planes or cylinders

• Cones to planes

• Spheres to cylinders or planes

• Circular edges to straight or circular edges

The 3D-symmetry constraint aligns 3D solid elements symmetric to a selected plane.
