Below is my initial attempt to translate the ProCAD GUI and documentation. A lot of work is still ahead.

Hopefully, this will develop into a series of pages, including a manual, translations, tutorials etcetera. Why not a CAD Mode in Blender?

Feel invited!

Main script window

This table is supposed to be a list with brief descriptions for quick reference. Some clean-up and reordering needed.

I've been using Blender 2.48a ProCAD 2.5 while investigating the script. The documentation I've managed to find is for Blender 2.42 ProCAD 2.2. I have been unable to run ProCAD 2.6 under any version of Blender.

CPA - Circle-Polygon-Arc

CPA (Circle-Polygon-Arc, "Cerchi-Poligoni-Arco") - Create circles, polygons, and arcs inscribed or circumscribed into/onto a circumference. (Edit Mode)

Takes a single vertex as its initial input (use SKEY in script window) and a series of other vertices. Ouput is generated in the coordinates of the active 3D view.

For most options only the principal data are necessary. The other fields can be applied to all figures created.

Input alternatives

Required input for the various available input alternatives.

MIS - Measurements

• MIS (Misurazioni, Measurements) - Returns various measurements.
  • Valid input is either
    • Two 3D cursor points in memory and a vertex at current location of 3D cursor
      • Position the 3D cursor on point 1, press MC.
      • Position the 3D cursor on point 2, press MC.
      • Position the 3D cursor on a vertex, press MIS.
    • Two selected vertices and a vertex at current location of 3D cursor
    • A selected line

ELL - Ellipse

• ELL (ELLISSI, Ellipse) - Create an ellipse.

POL - Polar polyline

• POL - (Edit Mode) Creates a line. Opens a dialogue for polar coordinates relative to the current view and the selected vertex. Automatically selects the created vertex. (Lunghezza=Length, Angolo piano=Planar angle, Angolo incl.=Angle of inclination.) Angles clockwise from Y axis (up in view coordinates). NOTE: An angle of inclination of 90 or -90 degrees will create an endless line unless Lunghezza 3D is enabled.
  • The "Lunghezza XY/3D" button determines if Length is based on Global coordinates (real length of line = Length) or viewport coordinates (appearent length of line in viewport = Length (off, default)).
  • "Angolo relativo" determines if the angles are based on 3D space coordinates (default up in the 3D viewport) or coordinates stored in memory (i.e. in the direction of the stored coordinates).

PAR - Parallel lines

• PAR (Parallela, "Parallel", PKEY) - Create parallel lines. Edit Mode, Vertex and Edge Selection Mode only.
  • A dialogue asks for two inputs: Distance ("Distanza") between the lines and Correction Z ("Correzione Z"), a Z offset.
  • Parallel lines are added in the direction of the 3D cursor, so Distance must always be positive. Valid input include two non-connected vertices.
  • Parallel Multiple (OR Key) - ???
    • Execute PAR on several lines. Output is different in edge and vertex selection modes.

SMU - Bevel, smooth

• SMU (Smussa, "Smooth") - Bevel an angle between two connected lines.
  • Select the first line and click MS to add it to memory. Then select the other line and click SMU to create the bevel. A dialogue opens asking for a number of vertices ("Num.spicchi") and a radius ("Raggio").
  • The lines must be coplanar to ensure there is a common vertex.

RAC - Join, extend

• RAC (Raccorda, "Join") - Extend two lines to a common intersection.
  • If the extension of one line intersects the other line or the extensions of both lines intersect, two lines will be added stretching from that intersection to the nearest two endpoints of the original lines. For non-coplanar lines the appearent intersection in the current view will be created. Arbitrary results is produced for odd input (i.e. intersecting and overlapping lines) with a preference for shortest distance for the extensions returned.
  • The 3D cursor is relocated to the newly added intersection but the two original lines remain selected.

CO

• CO -

SPI - Edge

• SPI - (Spigolo, "Edge") Add two cardinal lines separated by a 90 degrees angle between two vertices. (View coordinates). The 3D cursor is relocated to the newly added vertex.

TAG

• TAG -

SPE

• SPE -

PRO - Project

• PRO (Project, "Proietta") - Project vertices.
  • Projects current vertex selection onto cardinal planes (i.e. XY, XZ, and YZ planes). Created vertices are separate objects included into the current selection set in Object Mode. Vertices are projected relative to the position of the 3D cursor

CCS - Center Cursor-Selection

• CCS - (Center Cursor-Selection) Center cursor between current 3D cursor and active vertex

CCC - Center Cursor-Cursor

• CCC - (Center Cursor-Cursor) Center cursor between 3D cursor and 3D cursor coordinates stored in memory (MC).

Center Selection-Selection

• CSS - (Center Selection-Selection) Center 3D cursor between two selected vertices and add vertex at this position. (Use the /2 and </> buttons on the right to pick other positions than the midposition.) A dialogue follows with the optional choice of adding a perpendicular line (2D, top view) from the location.

MS - Selection to Memory

• MS - (Memory Selection, SKEY) Adds a maximum of 20 selected vertices to memory.

MC - Cursor to Selection

• MC - (Memory Cursor) Adds a maximum of 20 3D cursor positions to memory.

XYZ - move 3D Cursor

• XYZ - Moves the 3D cursor. Dialogue opens for distance. Toggle axes on/off with the X, Y, and Z buttons on the right.

ORT

• ORT -

VDI

• VDI -

S>C

• S>C (Snap Selection-Cursor) - Snap vertices of active object selection to 3D cursor.
  • If excecuted with individual vertices in edit mode, all vertices of the active object are snapped to the 3D cursor. Object centers are not affected.

V3D

• V3D -

DIM

• DIM -

Right panels

• REMDOUB - Automatic removal of double vertices, toggles on/off.
  • Removes doubles below threshold distance.
• <0,001> - Threshold for REMDB
• X, Y, Z -
• / 2 -
• </> -
• C/S -
• DEC: 3 - Decimals to use for rounding (?)
• PROCAD - List of PoCAD hotkeys
• BLENDER - Selected list of Blender hotkeys
• ESCI - (EKEY) Exits the script.
