Modifying entities - Express

Modify

Move/Copy/Rotate
  1. Move, copy, rotate and scale objects with a single command.
To move, copy, rotate and scale objects with a single command
  1. Do one of the following:
  2. Choose Express > Modify > Move/Copy/Rotate.
  3. Type mocoro and press Enter key.
  4. Select the desired entities and press Enter.
  5. Specify a base point.
  6. Type one of the following method of entering and press Enter:
  7. Move Move the selected entities in a new position after having specified the displacement point.
  8. Copy Copy the selected entities in a new position after having specified the displacement point. Press Enter to go back to the main options menu.
  9. Rotate Rotate the selected entities by the angular value specified by the user. Specify another point to determine the angle in relation to the base point or digit an angular value and press Enter.
  10. Scale Scale the selected entities. Specify a point to determine the scale factor or digit the scale factor and press Enter.
  11. Base Reset the position of the base point. Specify the new position of the base point.
  12. Undo Delete the last change.
  13. Exit Ends the command.
Extended Clip
  1. Clips xrefs or images with lines and curves.
    Allows curved clipping of blocks, xref drawings, images, and Wipeouts using polylines, circles, arcs, ellipses or texts.
To make an extended clip
  1. Do one of the following:
  2. Select Express > Modify > Extended Clip.
  3. Type clipit and then press Enter.
  4. Draw arcs, circles, and/or polylines to define clipping boundaries for blocks, xrefs, images and wipeouts.
  5. Pick a polyline, circle, arc, ellipse or text object for clipping edge...
  6. Pick an image, a wipeout, or an xref/block to clip...
  7. Enter the maximum allowable error distance for resolution of arc segments <0.1>:
  8. Clipit makes clipping to curved boundaries workable by traversing arc segments with a series of short straight segments. Clipit lets you specify the maximum distance between the midpoint of any given segment and the arc to control the precision with which it traverses arc segments.
  9. Entering a large error value generates fewer segments and faster progeCAD performance, but arcs appear less smooth. On the contrary, entering a very small value results in smooth clipping of arcs, but slows down progeCAD during the regeneration process of a drawing.
  10. Note To increase performance, enter relatively large values while creating your drawing and, when you are ready to plot, use CLIPIT again and specify a smaller error value for arc resolution.

  11. Pick (dynamic) Specify a point to select the angle or type an angular value and press Enter key. Click a point to determine the distance between the lines and the columns. Specify with the mouse another point to determine the area to be filled. Press Enter key to end.
  12. Measure Specify a point to select the angle or digit an angular value and press Enter. Click a point to determine the distance between the lines and the columns. Specify with the mouse another point to determine the area to be filled.
  13. Divide Specify a point to select the angle or digit an angular value then press Enter. Click a point to determine the distance between the lines and the columns. Digit the number of columns and press Enter. Digit the number of lines and press Enter.
Extended offset
  1. This offset command improved version, offers many advantages among which are: the layer control, the undo and multiple options.
To execute extended offset
  1. Do one of the following:
  2. Choose Express > Modify > Extended Offset.
  3. Type exoffset and press Enter key.
  4. Click two points or digit the distance and press Enter to define the offset.
  5. Digit Option and press Enter to access to the advanced options.
    Digit one of the following options and press Enter:
  6. Distance Reset the distance for the offset. Click two points or digit the distance and press Enter to define the offset.
  7. Layer Specifies the layer for the new objects. Digit one of the following options:
  8. Source Place the new entities on the same layer of the reference entities.
  9. Current Places the new entities on the current layer.
  10. Gaptype Sets and changes the offset mode controlled by the variable OFFSETGAPTYPE. Digit one of the following options and press Enter:

Delete duplicate objects
  1. Removes unnecessary objects which geometry is redundant by deleting duplicates and combining line and arc segments that overlap. For example:
  2. · Duplicate copies of objects are deleted
  3. · An arc drawn directly over a portion of a circle is deleted.
  4. · Two lines drawn at the same angle so that they partially overlap are combined to form a single line.
  5. · A duplicate line and/or arc segments within polylines are removed.
To delete duplicate objects
  1. Do one of the following:
  2. Choose Express > Modify > Delete duplicate objects.
  3. Type overkill and then press Enter.
  4. After having selected objects in the overkill dialog box, set options for deleting duplicate objects and then confirm with OK.
  5.  
  • Object comparison settings: the settings of this section of the dialog box control how OVERKILL compares objects.
  • Ignore options: all the options under Ignore have similar behaviour. For example, when the Ignore Layers option is selected, OVERKILL ignores object layers when comparing objects. Thus, two overlapping objects that reside on different layers may be considered equivalent. This option allows objects on different layers that overlap to be deleted or modified, to resolve duplication and/or overlap.
  • Numeric fuzz: the Numeric Fuzz value allows you to set the precision with which OVERKILL makes numeric comparisons. If this value is 0, two objects being compared must match before OVERKILL deletes or modifies one of them. On the other hand, if the fuzz value is higher than 0, two objects being compared do not have to match one of them to be deleted or modified.
    The fuzz value works in this way for other numeric comparisons such as X, Y and Z coordinate comparisons, as well as object comparisons involving scale, height, width, and so on.
  • Lines, Arcs and Plines: the settings of this section of the dialog concern how overkill deals with lines, arcs and plines.
  • PLINES - Optimize segments within plines. When the Plines option is selected, overkill checks individual line and arc segments within selected plines and removes any duplicate or unnecessary vertices. Also, if a pline segment duplicates a line or an arc object, one of them is deleted. If this option is not selected, overkill examines each pline as a single unit; that is, it deletes a pline only if it is a duplicate of another pline.
  •  
  • OVERLAP - Combine co-linear objects that partially overlap. The Overlap option controls how overkill handles objects that partially overlap one another. When this option is selected, objects that overlap are combined to form a single object. Otherwise, if this option is not selected, overkill does not change partially overlapping objects.
    For example, you have a horizontal line and another horizontal line drawn from the midpoint of the first line to a point beyond the end of the first line. (See the following illustration) The second line partially overlaps the first line. If the Overlap option is selected, overkill combines the two lines to form a single line that extends from the leftmost point to the rightmost point. If the Overlap option is not selected, no change is made.
    (The red X marks show the endpoints of the first line and the blue X marks show the endpoints of the second line.)
  •  
  • END to END - Combine co-linear objects when aligned end to end.
    Using this option, you can combine co-linear objects that have common endpoints. The following illustration shows how overkill works with the End to End option: the red X marks show the endpoints of the first line and arc. The blue X marks show the endpoints of the second line and arc.
