PEdit

2D Polyline Option

Description

Edit vertices

Edit vertices; prompts you:

Edit vertices: Next/ Previous/ Angle/ Break/ Insert/ Move/ Regen/ SElect/ Straighten/ Width/eXit/ <Next> - enter an option

BricsCAD displays a triangle marker at the start of the polyline, and an X marker at the current vertex.

• Enter Next or Previous to move the marker from vertex to vertex
• Enter the SElect option to select the vertex directly

Note: It is much easier to edit the vertices of a polyline with grips editing.

Next

Moves the X marker to the next vertex. When the marker reaches the last vertex of a closed polyline, it does not move to the "next" (first) vertex.

Previous

Moves the X marker to the previous vertex.

Angle

Changes the angle of the current segment; prompts you:

Included angle for segment (>0 is ccw, 0 is straight, <0 is cw) <0> - enter an angle:

Break

Removes segments from the polyline between the two vertices marked with X markers. This action turns:

• Closed polylines into open polylines
• Open polylines into two polylines, with a gap between them

This action cannot be undone. Prompts you:

Next/Previous/Select/Go/eXit/<Next> - enter an option to move the X marker along the polyline:

• Next - choose the next vertex
• Previous - choose the previous vertex
• Select - moves second X marker directly to another vertex; prompts you:
  

  Select point along segment move to - pick a point on the polyline. The program places the second X marker on the vertex nearest to the pick point; this option is faster than using Next and Previous.

• Go - break the polyline between the first and second marked vertices

• eXit - return to the previous prompt

Note: It is much easier to use the Break or Trim commands to remove part of a polyline.

Insert

Inserts a vertex. A drag line previews the location of the new vertex; prompts you:

Location of vertex - pick a point for the new vertex. The program adds a vertex and a segment:

Move

Moves the current vertex. Ahe drag line previews the new location of the vertex.

Prompts you:

New location for vertex - pick point to move the vertex. The program moves the vertex and associated segments.

Note: It is much easier to move the vertices of a polyline with grips editing.

Regen

Regenerates the polyline to show changes made by the editing actions of this command.

SElect

Moves the X marker directly to another vertex; prompts you:

Select point along segment to edit - pick a point on the polyline; the program places the X marker on the vertex nearest to the pick point. This option is faster than using the Next and Previous options.

Straighten

Removes all segments between two vertices. When you select the start and end points of an multi-segment polyline, the entire polyline is straightened, becoming a single segment; this also applies to closed polylines.

Prompts you:

Straighten: Next/Previous/Select/Go/eXit - enter an option

• Next - moves the second X marker to the next vertex
• Previous - moves the second X marker to the previous vertex
• Select - moves second X marker directly to another vertex; prompts you:
  Select point along segment move to - pick a point on the polyline
  
  
• Go - replaces the segments between the two marked vertices with a single segment:

  

  This action cannot be undone.

• eXit - exits this sub-sub-option; returns to the previous prompt

Width

Changes the width of the current segment; prompts you:

1. Enter new starting width - specifies the width at the starting end of the polyline
2. Enter new ending width - specifies the width at the polyline's end

The "current" segment lays between the X-marked vertex and the next vertex.

eXit

Exits this sub-option; returns to the previous prompt

Close

Closes the polyline by adding a segment between the start and endpoints.

When the polyline is closed, this option reads Open.

Open

Opens closed polylines by removing the last segment drawn to close the polyline.

When the polyline is open, this option reads Close.

Decurve

Reverses the effects the Fit and Spline options.

Fit

Fits a curve to the polyline.

To unfit the polyline, use the Decurve option.

Join

Adds open entities to the selected polyline; prompts you:

Select entities to join - choose an entity:

• Line
• Arc
• Polyline segment and arc
• Helix

This option works only with open and with cojoined entities. Cojoined means that the endpoints of entities meet, such as when drawn with ENDpoint object snap or with the Last point option. The joined entities take on the source polyline's properties, such as color, width, and layer.

When editing multiple polylines, prompts you:

Enter fuzz distance or [Jointype] - do one of the following:

• Press Enter to create one or more polylines with cojoined lines, polylines, and arcs in the selection set.
• Enter a so-called 'fuzz distance' then press Enter to create one or more polylines from the entities in the selection set. When endpoints are within the fuzz distance, the entities are extended or trimmed.
• Type J to specify the type of joining; prompts you:
  Specify type of joining: [Extend/Add/Both] - enter an option to specify what happens when entities lie within the fuzz distance:
     Extend - extends or trims segments to the nearest endpoints
     Add - adds linear segments between the nearest endpoints
     Both - extends or trims if possible, otherwise adds linear segments

The program then reports the number of polylines created.

Linetype-mode

Determines how linetype appear on polylines; prompts you:

Linetype continuous along polyline: ON/OFF <OFF> - enter an option:

• ON - linetypes start and stop at the polyline's start and endpoints
• OFF - linetypes start and stop at each vertex

This option is stored in the PLineGen variable.

Reverse

Reverses the direction of the polyline: the starting point is now its end point, and vice versa. The polyline does not change its look with this operation. This option affects operations that depend on the direction of a polyline, such as vertex editing. The polyline does not change its look with this operation, except that the triangle marker moves to the other end of open polylines.

Spline

Converts the polyline into a spline.

All width information is lost; use the Width option to reapply width. The spline is a Bezier-spline whose smoothing is defined by the SplineType system variable.

Taper

Tapers the width of the entire polyline from one end to the other; prompts you:

• Enter new starting polyline width - specify the width at the starting end of the polyline
• Enter new ending polyline width - specify the width at the polyline's end

Width

Changes the width of all segments; prompts you:

Enter new width for all segments - specify a width

This option overrides tapered widths.

Undo

Undoes the last action.

eXit

Exits the command.

3D Polyline Option

Description

Edit vertices

Edit vertices; prompts you:

Edit vertices: Next/ Previous/ Break/ Insert/ Move/ Regen/ SElect/ Straighten/ eXit/<Next> - see the options for 2D polylines, above

The Angle and Width options are missing from the prompt, because 3D polylines cannot contain arc segments and cannot have width.

3D Polyface Mesh Option

Description

Edit vertices

Moves vertices; prompts you:

Edit vertex (0,0): Select/Next/Previous/Left/RIght/Up/Down/Move/REgen/eXit - enter an option. BricsCAD displays a triangle marker on the home vertex (0,0) and an X marker on the current vertex.

It is easier to move vertices using grips.

Select

Moves X marker directly to another vertex; prompts you:

Select point along segment to edit - pick a point on the mesh.

The program places the X marker on the vertex nearest to the pick point. This option is faster than using the Next and Previous options.

Next

Moves the X marker to the next vertex. When the marker reaches the last vertex, it does not move to the "next' (first) vertex.

Previous

Moves the X marker to the previous vertex.

Left

Moves the X marker to the vertex on the left.

RIght

Moves the X marker to the vertex on the right.

Up

Moves the X marker to the higher-numbered vertex.

Down

Moves the X marker to the lower-numbered vertex.

Move

Moves the current vertex; prompts you:

New location for vertex - pick a point to move the vertex. The drag line previews the new location of the vertex.

BricsCAD moves the vertex and associated faces.

REgen

Regenerates the polyline to show changes made by the editing actions of this command.

eXit

Exits this sub-option; returns to the previous prompt line.

Desmooth

Removes the Bezier-spline smoothing of 3D meshes.

Mclose

Closes the 3D mesh in the m direction:

When the mesh is closed, this option reads MOpen.

Mopen

Opens the 3D mesh in the m direction. When the mesh is closed, this option reads MClose.

Nclose

Closes the 3D mesh in the n direction:

When the mesh is closed, this option reads NOpen.

Nopen

Open the 3D mesh in the n direction. When the mesh is closed, this option reads NClose.

Undo

Undoes the last action.

eXit

Exits the command.
