Problem with Fillet Radius command???

[AutoCAD Slave]

Hi,

Sometimes when i use the fillet command set at ZERO to join two lines to a point it tells me it cannot be done and the the lines are not coplanor, what does this mean and why won't the lines join each other??

Thank you in advance.

are you working in 3d? If so, the computer is right. Check to see of they are actually attatched or if one is just floating in space. Adjust accordingly.

Coplanar means "in the same plane". Lines can only be filleted if they are drawn in the same plane. Often when working in 3D your lines may be drawn in different planes.

Select one of the lines, hit Ctrl+1. PROPERTIES docker pops up and then look for the Z value, normally that would be the ht. Remember it. Select the other line and adjusts it's Z value if it is diff.

Alternatively, you can use this lisp.

;;; FLATTEN sets the Z-coordinates of these types of objects to 0
;;; in the World Coordinate System:
;;;  "3DFACE" "ARC" "ATTDEF" "CIRCLE" "DIMENSION" 
;;;  "ELLIPSE" "HATCH" "INSERT" "LINE" "LWPOLYLINE"
;;;  "MTEXT" "POINT" "POLYLINE" "SOLID" "TEXT"

;;; Thanks to Vladimir Livshiz for improvements in polyline handling
;;; and the addition of several other object types.
;;;
;;; You are free to distribute FLATTEN.LSP to others so long as you do not
;;; charge for it.
;;;
;;;-----------------------------------------------------------------------
;;;*Why Use FLATTEN?
;;;
;;; FLATTENing is useful in at least two situations:
;;;  1) You receive a DXF file created by another CAD program and discover
;;;     that all the Z coordinates contain small round-off errors. These
;;;     round-off errors can prevent you from object snapping to
;;;     intersections and make your life difficult in other ways as well.
;;;  2) In a supposedly 2D drawing, you accidentally create one object with
;;;     a Z elevation and end up with a drawing containing objects partly
;;;     in and partly outside the Z=0 X-Y plane. As with the round-off
;;;     problem, this situation can make object snaps and other procedures
;;;     difficult.
;;;
;;; Warning: FLATTEN is not for flattening the custom objects created by
;;; applications such as Autodesk's Architectural Desktop. ADT and similar
;;; programs create "application-defined objects" that only the
;;; application really knows what to do with. FLATTEN has no idea how
;;; to handle application-defined objects, so it leaves them alone.
;;;
;;;-----------------------------------------------------------------------
;;;*How to Use FLATTEN
;;;
;;; This version of FLATTEN works with AutoCAD R12 through 2000.
;;;
;;; To run FLATTEN, load it using AutoCAD's APPLOAD command, or type:
;;;   (load "FLATTEN")
;;; at the AutoCAD command prompt. Once you've loaded FLATTEN.LSP, type:
;;;   FLATTEN
;;; to run it. FLATTEN will tell you what it's about to do and ask you
;;; to confirm that you really want to flatten objects in the current
;;; drawing. If you choose to proceed, FLATTEN prompts you to select objects
;;; to be flattened (press ENTER to flatten all objects in the drawing).
;;; After you've selected objects and pressed ENTER, FLATTEN goes to work.
;;; It reports the number of objects it flattens and the number left
;;; unflattenened (because they were objects not recognized by FLATTEN; see 
;;; the list of supported objects above).
;;;
;;; If you don't like the results, just type U to undo FLATTEN's work.
;;;
;;;-----------------------------------------------------------------------
;;;*Known limitations
;;;  1) FLATTEN doesn't support all of AutoCAD's object types. See above
;;;     for a list of the object types that it does work on.
;;;  2) FLATTEN doesn't flatten objects nested inside of blocks.
;;;     (You can explode blocks before flattening. Alternatively, you can
;;;     WBLOCK block definitions to separate DWG files, run FLATTEN in
;;;     each of them, and then use INSERT in the parent drawing to update
;;;     the block definitions. Neither of these methods will flatten
;;;     existing attributes, though.
;;;  3) FLATTEN flattens objects onto the Z=0 X-Y plane in AutoCAD's
;;;     World Coordinate System (WCS). It doesn't currently support
;;;     flattening onto other UCS planes.

Or use this version from our AutoLISP Archive.

[AutoCAD Slave]

cheers dudes.

[|-TK-|]

Does anyone have a version or other method to flatten drawings containing to many block to use this inside every block?

[Spageddie]

Anyone ever considered the FLATTEN in the express tools ?

[Cadastrophic]

Can Express Tools from R14 be used with 2004? I can't find ET in 2004.
