How to linearly align the selected objects in ZWCAD


Both the ALIGN command of one pair of points and two pairs of points can be used to linearly 
align the selected objects in ZWCADThe method is the following:
Command line:  align
Ribbon: Home » Modify »align

One pair of points: Specify one pair of source and destination points, move the selected 
object from the source point 1 to the destination point 2.
Steps:
Enter ALIGN to start the command;
Select the objects which need to be aligned;
Specify the first source point (e.g. point 1 in picture 1);
Specify the first destination point (e.g. point 2 in picture 1);
Press ENTER to end align, see the result in picture 1.

Techniques of using Shift keyboard in ZWCAD


Issue: 
Shift key on the keyboard is useful for drafting in cad cam software. You want to know some techniques of using the Shift key.

Solution :

  1. To add or delete entities with Shift key in cad drafting software
    After select some entities in the drawing, you want to add more entities to the selection set or delete some entities which are already in the selection set, you can press Shift key on the keyboard and then pick the entities that you want to add or delete.
    OptionsUseShiftToAddToSelection
    Note: This way work only if the ‘Use Shift to add to Selection’ option in Options dialog box is checked.
  2. Use Shift key to snap the specific point in cad design software.
    With the Entities Snap feature, we can advance the definition to design our works. But the detailed setting seems a little more annoying while using. If the snapping modes are turned on too few, it’s not conveniently to capture some points; and it’s easy to capture the wrong points among near distance while the snapping modes are turned on too more.
    Now you can take a try to click the right –mouse button with pressing the Shift keyboard at the same The detailed snap settings will pop up as a list-menu. And you can activate one mode to use. So with Shift button, it’s easy to employ this feature now.
  3. Use Shift button to trim or extend entities. 
    Trim command and Extend command are used frequently while editing drawings. And do you notice the detailed prompt on the command line?
    For Trim command: seclect entity to trim, or press Shift and select entity to extend, or [Edge mode/Fence/Projection]:
    For Extend command: Seclect entity to extend, or press Shift and select entity to trim, or [Edge mode/Fence/Projection]: 
    It means we can switch conveniently between these two commands with the Shift button. That is practical while applying these two commands frequently.

Export Drawings to Other File Formats


Export and convert ZWCAD drawings as other file formats. ZWCAD surports the output file format containing: WMF, DXF, BMP, DWG, DWT, EMF, SVG, PDF, EPS, DWF, SAT.


WMF
Exports drawing files as element files (.wmf) using WMFOUT or EXPORT command. As a Windows metafile format, WMF file includes lots of vector drawings or raster images. Generally, ZWCAD creates WMF files in vector drawings which are easy to pan or scale.

DXF
As a drawing exchange file, DXF file contains text file of drawing information that are accessible for all the other CAD systems. If someone else is using CAD applications capable of identify DXF files, you can share the drawing by saving drawing as DXF file.
User can export files as DXF format using Save or Save As command, select DXF file format from the Tools button of the Export dialog box, when saving the drawing as DXF format. DXF files are also saved as ASCII or binary format.
Specify precise decimal digits as you saving drawing as DXF file, controls floting-precision up to 16 digits for DXF files. You can also click Select Object option to save some objects as DXF file.

BMP
As bitmap file format, BMP is a kind of raster image format. The object displayed on screen together with colored viewport and objects in rendered viewport will be displayed in raster images as well.
Export the entire drawing or partly export the drawing to device-independent raster images using EXPORT command.

DWG
DWG is standard drawing file format generally supported by CAD software.

DWT
You can export drawings as DWT template file using Save or Save As command.

EMF
EMF is fortified Windows relay file.

SVG
SVG is upgradeable vector graphics.
To export a drawing to a BMP, EMF, WMF, or SVG file
  1. Choose File > Export.
  2. In the Export Drawing As File dialog box, under Save As Type, choose the file format.
  3. Specify the name of the file you want to create.
  4. Click Save.
  5. If the selection prompt box displays, choose the entity-selection method, and then create the selection set.
  6. When you have finished selecting entities, press Enter.
Command line EXPORT

PDF
The EXPORT command is available for exporting the drawing as a PDF file.
PDF files allow you to distribute your drawing to others for viewing in Adobe® Acrobat ® Reader®, which is free software that users can download. PDF files can also be viewed, reviewed, and edited in Adobe® Acrobat.

To export a drawing to a PDF file
  1. Choose File > Export.
  2. In Save As Type, choose Portable Document Format (pdf).
  3. Specify the name of the file you want to create.
  4. Click Save.
  5. Choose the entity-selection method, and then create a selection set that contains the entities you want to export.
  6. When you have finished selecting entities, press Enter.
Command line EXPORT

EPS
EPS format is housed PostScript file, a drawing file can be exported as EPS file using EXPORT command.
PostScript file formats are most available for desktop publishing applications. With plotting capability of high resolution, this file format is suited for raster images, such as GIF, PCX and TIFF. Once you have converted the drawing into PostScript format, you can use PostScript font.
To export files as EPS from layout tab, you should execute from File-Plot, to start Plotting dialog box, select plotter as ZWCAD Virtual EPS Plotter, and click Plot to File option, and then click OK to close Plot dialog box. And next, start PLT dialog box, in which user can specify saving path and file name, save the file with extensions .eps.

Controllable Properties of PostScript
When exporting drawing as EPS files in PostScript format, some objects will be rendered. Affects the following properties:
  • Text, attribute definitions and attributes. If replace the font supportive of PostScript with the font with specified conversion text object, text will be plotted in specified PostScript font. Or else, render the text with frame character.
  • Bold font and text control code. If the text with thickness over 0 or contain control code( such as %%O or %%D). But rendered text will not plotted as PostScript font. International symbol and special symbol exported as PostScript font.
  • ISO 8859 Latin/1 character set, if use character value among 127 to 255 for text, explain this text according to ISO 8859 Latin/1. If this character appears in the text reflected to PostScript, re-mapping a version of generating code vector to display ISO character set. The text generated from re-mapping will be exported in PostScript compatible format.
  • Circle, arc, ellipse, elliptic arc. Arcs and circles will be converted into corresponding PostScript path object if they have thickness.
  • Fill solids. Plot the Fill solids in PostScript path.
  • 2D polyline. Exports the 2D (planar) polyline with unify width, PostScript restricts system settings as proximate lines combination with end seal and mitre.

DWF
Export ZWCAD drawings as Web DWF formats, As a two dimension vector file, DWF publish ZWCAD drawings on Web or Intranet network.
DWF file supports realtime panning or scaling and controls how the layers and named views are displayed.

SAT
Exports solids, region, ACIS entities as SAT format using ACISOUT command. Additionally, trimmed ShapeManager objects of the NURBS face, region and 3D solids are also exported as SAT file.

To export an ACIS file
  1. Choose File > Export.
  2. Select the ACIS entities you want to save.
  3. Specify the name of the file you want to create.
  4. Click Save.
Command line EXPORT

Command Reference
ACISOUT: Exports ZWCAD solid objects to an ACIS file
BMPOUT: Saves selected objects to a file in device-independent bitmap format
EXPORT: Saves objects to other file formats
PLOT: Plots a drawing to a plotter, printer, or file
SAVEAS: Saves a copy of the current drawing under a new file name
WBLOCK: Writes objects or a block to a new drawing file
WMFOUT Saves objects to a Windows metafile
System Variables Reference
FACETRES: Adjusts the smoothness of shaded and rendered objects and objects with hidden lines removed
WMFBKGND: Controls the background display when objects are inserted in Windows metafile (WMF) format
