What was new in DataCAD 15?

Where to find the new feature
Helpful hints

DataCAD 15 includes an enhanced Sun Shader built around an all-new rendering engine optimized for speed, enabling you to review complex models with ease. An updated user-interface makes navigation easier and you can now save GoTo Views for later recall. Rendering quality has also been improved by adding support for transparency and smoothing. Incorporating shadow maps into your DataCAD drawings is now automated with a new 'Superimpose Saved Image' feature.

Transparency
Sun Shader 2.0 has support for transparent materials, such as glass. When you assign a transparent material to an object, Sun Shader 2.0 will display it as transparent, enabling you to see through it. Shadow Study mode also supports transparency, so you can see the effect of sunlight through windows.

GoTo Views
The GoTo View toolbar in Sun Shader 2.0 enables you to save view parameters, including rotation angle and zoom level. Click the “Add View” button to add the current view to the list, click on “Update View” to update the selected view with the current view parameters, or click on “Delete View” to delete the selected view from the list. Click the drop-down view menu to select a saved view from the list and display it on the screen.

Layer Manager
Click the Layer Manager toolbar button to open the Sun Shader Layer Manager. It provides access to the layers that were turned on in your model when you launched the Sun Shader from DataCAD. Use it to turn layers in the model on and off without having to close the Sun Shader and return to DataCAD, making it easier to explore construction options and see their effect on the Sun path and shadows. The Layer Manager contains familiar commands, such as All On, Set Active and Active Only. In addition, options for Select All, Deselect All, and Invert Selection are available.

Edge Properties
There is an Edge Properties drop-down toolbar button which contains options for defining the properties of edges in your model. It includes options to use the entity color or a specific color, and the ability to define the width (in pixels) that each edge should be displayed.

Smoothing
Sun Shader 2.0 has support for smoothing in material properties. When enabled, curved edges will not display facets, and will instead appear as smooth curves.

Other toolbars
Other toolbars, added for convenience, include the Zoom Toolbar, the Rotate Toolbar and the Review Toolbar. From left to right, the Zoom Toolbar has buttons for zoom extents and zoom window. The Rotation toolbar has buttons that rotate the model counter-clockwise about the Z axis, clockwise about the Z axis, counter-clockwise about the X axis or clockwise about the X axis. When Shadow Study mode is off, you may use the Review Toolbar to check face winding, draw face normals, draw vertex normals, and also to show the positive (outside) face, the negative (inside) face, or both.

Shadow Study Results
Shadow study results, including location, date and time, and Sun position, are now displayed as text in the upper left of the Sun Shader viewing window when Shadow Study mode is enabled.

Pan/Zoom/Rotate Widget
The Pan/Zoom/Rotate widget is available in the "View" pull-down menu. When checked, it is displayed in the lower right corner of the Sun Shader 2.0 interface. Clicking the left and right arrows rotates the model about the Z axis, while clicking the up and down arrows rotates the model about the X axis. Pressing and holding the [Shift] key while clicking the arrows will pan in the selected direction. Clicking the center circle restores the model to the initial view. Clicking the middle circle and then dragging the cursor clockwise about the center point zooms in on the model, while dragging counter-clockwise zooms out.

Sun Shader 2.0 is accessed via the “Sun Shader” option in the “View” pull-down menu, or the Sun Shader button on either the “Rendering” or “Viewer” toolbar.

An option labeled “Flatten all entities to zero” has been added to the Export dialog when exporting a file to DXF or DWG format. When checked, DataCAD will automatically change the Z-Base and Z-Height of all entities in the resultant DXF or DWG file to zero, placing them flat on the ground plane.

The option to ignore the drawing-level Clip Cube has been added to the [Ctrl]+[Right-click] context menu for XREF entities. It is remembered on a per-XREF basis, and is off by default. If you check this option, the XREF will ignore the drawing-level Clip Cube and display the entire XREF outside of the Clip Cube. When un-checked, only portions of the XREF that lie inside the drawing-level Clip Cube will be displayed; any portion of the XREF which is outside the clipping boundary will be suppressed from the view.

Note: XREFs that have an XClip active will ignore the drawing-level Clip Cube.

The toggle "Remember Layer Settings for GoTo Views" has been removed from the "Reference File Management..." menu in the "Insert" pull-down. It has been renamed "GTV Link," and can be found in the Reference File Manager, the XREF Properties dialog, and the [Ctrl]+[Right-click] context menu for XREFs. This setting is remembered on a per-XREF basis.

The GTV Link feature now supports per-XREF highlighting in addition to the per-XREF-layer highlighting that was previously supported. Using this feature, you can insert an XREF and assign highlight color, line type and line spacing, and then save a GoTo View in the host drawing. You can then assign different (or no) highlight color, line type and spacing, save another GoTo View in the host drawing, and DataCAD will remember these settings when switching between GoTo Views.

If the "GTV Link" in the Reference File Manager is set to "On," the status of the "Ignore Clip Cube" setting is remembered with the host-level GoTo Views in the drawing.

When an XREF is inserted with an enlargement factor, that same enlargement factor is now applied to the overshoot value for any objects in the XREF that have overshoot assigned by entity. Previously, no enlargement factor was assigned to overshoot.

The "Current Color" toggle in the Text/Arrow/Smart Arrows/Color menu will draw the arrow heads using the current layer color. Using this setting saves you the step of defining a color for arrow heads, and is remembered on a per-drawing basis.

The "Current Wgt" option in the Text/Arrows/Smart Arrows/Weight menu will draw the arrow heads using the current line weight. Using this setting saves you the step of defining a line weight for arrow heads, and is remembered on a per-drawing basis.

Smart Arrow styles "Closed" and "Dot" support the KnockOut setting. When enabled, they will obscure any other information which occupies the same coordinates in the drawing area.

“Smart Arrow" has been added to the list of entities supported by selection mask. When selecting entities, choose “Mask,” pick “Entity” and then toggle “Smart Arrow” on. When you return to the selection menu, DataCAD will only select Smart Arrows.

The "1st Ortho" toggle in the Smart Arrows menu has been enhanced. When on, only the first segment of the Smart Arrow leader will be orthogonal, regardless of whether "Ortho Mode" is on or off in the "Tools" pull-down menu. Previously, if Ortho Mode was checked all segments of the leader would be drawn orthogonal; in order to draw only the first segment orthogonal, you had to turn 1st Ortho on and turn Ortho Mode off.

The [Ctrl]+[Right-click] context menu has been enhanced to display new options when executed while the cursor is positioned over a blank space in the drawing area.

·Selecting "Paste" will paste the contents of the Windows Clipboard.

· Selecting "Paste Special" will open the "Paste Special" dialog enabling you to select from the available formats (if applicable) to paste the contents of the Clipboard.

· Selecting "Paste As Symbol" will enable you to paste the current contents of the Clipboard as a symbol in the drawing, provided the Clipboard contains DataCAD information.

· Choosing "Clipboard Select" invokes the Clipboard Selection mode so that you can choose information to Copy to the Clipboard.

· Selecting "Save all drawing symbols to a folder" enables you to save all symbols currently instanced in the drawing to a selected folder on your hard drive. Note: DataCAD will not save nested-level symbols or symbols which are no longer instanced.

A temporary boundary box is displayed when creating or resizing MText and PText entities. Even if the MText or PText entity has “Boundary” turned off, this temporary box is displayed when you are placing or resizing the entity to show the limits of the object. This boundary is temporary, and disappears as soon as you complete the process of defining the word wrap edge. It will not display or print. There is a corresponding dcadwin.ini key that can disable this feature. See item 1 in the “New dcadwin.ini keys” section for details.

Smart walls that are drawn on different layers support the ability to have their intersections cleaned using the "T Intersect," "L Intersect," and "X Intersect" commands in the Cleanup menu. Layer Search must be toggled on for these to work. Previously, only Smart walls that were drawn on the same layer could have their intersections cleaned.

Added "Relocate" to the [Ctrl]+[Right-click] context menu for associative dimensions. Selecting this option puts DataCAD into dimension placement mode, so that you may reposition the dimension line using the existing dimension points.

The "Bisect" function in the Geometry/Tangents menu supports the ability to select Smart walls. Previously, only 2D lines were supported. After selecting “Bisect” from the “Tangents” menu, choose two Smart walls. DataCAD will rotate your cursor to match the angle of a line that would bisect the angle between the two walls.

The "Justify" command in the "Text" menu supports the ability to select 2D Lines, 3D Lines and Smart walls as the line of justification, using the "Entity" option in that menu. After selecting a justification line, and then exiting and returning to the menu, a "Prev. Line" option is now available, enabling you to use the previously selected justification line.

The "1-Line Trim" command in the "Cleanup" menu supports the ability to select individual wall lines of Smart walls when defining the “Trim To” line. Previously, this function was limited to selecting the control line.

A "Prev. Line" option has been added to the Cleanup/1 Line Trim menu. It enables you to choose a previously selected line as the trim-to line for the command. After choosing "Prev. Line," you then pick the outside of the line, and then proceed with choosing lines to trim.

An "Entity" toggle has been added to the "Mirror" menu which enables you to select a 2D Line, 3D Line or Smart wall to act as the line of reflection. The status of this setting is remembered on a per-drawing basis.

DataCAD supports the ability to select Circles in the "Line To Poly" function of the Polyline/Edit menu.

Area, Perimeter and Volume have been added to the list of information returned on the Coordinates/Hints toolbar when you "Identify" a bitmap.

The new toggle named "WYSIWYG" has been added to the Plotter menu. This toggle is only available when "Pen Sort" is off. When enabled, print order is exactly the same as screen display order, resulting in "What You See Is What You Get."

Added a "3-Sided Only" option to the 3D Explode/To Polygons command. When activated, exploding an object will result in a collection of 3-sided polygons. This can be useful when exporting a model to a rendering application.

The Layer Manager has new layer status indicators. If the layer name is drawn in black text, the layer is turned on. If the layer name is underlined, it is the current active layer. If the layer name is gray, the layer is turned off. If the layer name is red with a strikethrough, the layer is on and locked. If the layer name is gray with strikethrough, the layer is off and locked.

When you pick "Import" (and then either Replace or Merge) in the "Layers" menu to import a layer, the "Load from which file" dialog appears. The default name in the "File name" field is the same name as the layer which is currently active in the drawing, and was previously limited to eight characters. This limitation has been lifted, and the function now supports long layer names.

Show PText/MText Boundary On Entry/Resize
If TRUE, DataCAD will display a temporary boundary box around MText and PText entities when creating or resizing them.
If FALSE, a temporary boundary box will not be shown.

No LockSize
If FALSE, Lock Size is available in the Text and Dimension/Text Style menus (with Text Scale enabled).
If TRUE, the Lock Size button will no longer be displayed in the Text or Dimension, Text Style menus.

Shortcut Keys Invoke Alias
If FALSE, single-letter keyboard interrupts continue to function as they always have.
If TRUE, DataCAD directly accesses the Command Line Alias function and executes the selected command. This mode of command entry more closely mimics that of AutoCAD, and enables you to customize the keyboard commands. For example, you could set the [a] key to take you to the "Arrow" menu instead of the "Architect" menu. Multi-character aliases are also supported, for example "ZE" for "Zoom/Extents."

Spacebar For Distance Input
If FALSE, it is not necessary to press the [Spacebar] to invoke keyboard input.
If TRUE, direct distance input is disabled and you must press the [Spacebar] to invoke keyboard input.

The following extended character codes have been added:

1066# : Pen Sort On
1067# : Pen Sort Off
1068# : WYSIWYG On
1069# : WYSIWYG Off
1079# : Hatch On
1080# : Hatch Off
1081# : Fill On
1082# : Fill Off
1083# : Bitmaps On
1084# : Bitmaps Off
