At the end of the thread CADDapult writes out some code that seems to do what I want. Question is... how to do enter/use this code. I have not used code in autocad before (have done a small bit in excel).
In order to load lisp files, you have to issue the Appload command at the command line or in the Tools Menu, Load Application, and then in the command line again, type the command BlkXplode. In order to use other lisp files, you have to inspect the file for functions with the pattern: (defun C:SomeNameHere()...) They are Autolisp defined commands.
If there are any nested Blocks as ingredients in the definitions of other Blocks, and you want all of those also Exploded, you would want to run that several times. Or you could alter it to run itself as many times as it continues to find Blocks. In simplest terms:
However, that [and gasty's original] would also find Xrefs [and, if you ever use them, Windows Metafiles] that can't be Exploded. So really, it ought to run through each item in a selection set, and only if it's an Explodable kind of Insert object, Explode it. [Also, doing it that way (Exploding only one at a time), no messing with the QAFLAGS System Variable is necessary.] There should also be some kind of marker so it will know once it has encountered a selection set that contains no ordinary Blocks among the Insert objects it found, and stop checking -- otherwise it would get into an endless loop. I would bet that there's something out there already that will do something like that, but if you don't find it, it wouldn't be hard to work out.
The following program will recursively explode all primary & nested block references (nested to any depth) excluding xrefs, in all drawing layouts (the EXPLODE command will ignore objects in inactive drawing layouts):
Gaston's initial response did what I initally needed (although as Kent mentioned, does need to be rerun for nested blocks). I therefore marked it as the solution. However, Lee's solution is super sweet as it takes the repeat running out of it.
The loft itself works, but if I try to use polyline guides, it fails (with the error code 98037 - not that there's any way of telling what that means!). I've redrawn the guides three or four times in different ways, but they fail each time. I'm absolutely certain the guides intersect the profiles (although I've been wrong before!), but now they've taken error messages out of CAD 2018, tracking down the problem is nigh on impossible...
I've had a play with the paths and different ways of creating them - the weird looping path seems to be the result of joining a 2d polyline and a 3d polyline. I've attached another version of the file with one path I've re-drawn. This time, I've created the path as a polyline in two parts, to see if I could get half the shape to loft, but still no luck...
Went back to the original file and split the yellow profiles in half. This seemed to work for the part I lofted with guides. It doesn't seem to work all the pieces however. Is this intended to be symmetrical? Perhaps constructing a top and then a bottom in pieces might work better.
I tried repeating what you did and breaking the profiles into quarters, then lofting to create surfaces, but I can't even get it to do that! The lofting works, but any sort of guide line I use throws the same 98037 error.
...actually, despite my despairing of CAD's 3d abilities, I couldn't close the file for good and walk away without trying one last thing. My original guide lines running forward from the mid-section profile were formed from a straight line, a spline and then a tighter spline to get the required radius at the front of the object, all joined together. Although it changes the shape of the object slightly (the front radius is larger), a re-drew the guides with only one spline at the front instead of two and all the guides now work - I've attached a revised drawing.
I can't find a reference for the error code numbers anywhere. Is there a way to increase the error message verbosity? Previous versions of AutoCAD generated descriptive error messages, not just error code numbers. Fixing modelling errors with a descriptive guide to the problem is only achievable through trial and error...
I too wish I had access to a definitive list of what the error codes identify. Apparently they are only helpful to the Dev team. Do you have a model you want me to take a look at to see if I can figure out what might be failing?
I've centred the view on the lofting operation I'm trying to get working - there are two profiles - a 6-sided polygon and a 4-sided, long thin rectangle, joined by six polylines I'm trying to use as guides. Selecting any of the guides during the loft causes a modelling error.
I took a look at your model and found that if I zoomed in very tight, many of the lines did not connect at all. I rebuilt much of the geometry and then lofted parts together, ran SURFSCULPT and ended up with this 3D solid.
I've always trued to avoid generating/using surfaces - I tend to only encounter them when a 3d modelling operation (like loft or extrude) goes wrong - I'll certainly review their usefulness based on what you say.
AutoLISP is a dialect of the programming language Lisp built specifically for use with the full version of AutoCAD and its derivatives, which include AutoCAD Map 3D, AutoCAD Architecture and AutoCAD Mechanical.[1] Neither the application programming interface (API) nor the interpreter to execute AutoLISP code is included in the AutoCAD LT product line (up to Release 2023, AutoCAD LT 2024 includes AutoLISP).[2] A subset of AutoLISP functions is included in the browser-based AutoCAD web app.
AutoLISP is a small, dynamically scoped, dynamically typed Lisp language dialect with garbage collection, immutable list structure, and settable symbols, lacking in such regular Lisp features as macro system, records definition facilities, arrays, functions with variable number of arguments or let bindings. Aside from the core language, most of the primitive functions are for geometry, accessing AutoCAD's internal DWG database, or manipulation of graphical entities in AutoCAD. The properties of these graphical entities are revealed to AutoLISP as association lists in which values are paired with AutoCAD group codes that indicate properties such as definitional points, radii, colors, layers, linetypes, etc. AutoCAD loads AutoLISP code from .LSP files.[3]
AutoLISP code can interact with the user through AutoCAD's graphical editor by use of primitive functions that allow the user to pick points, choose objects on screen, and input numbers and other data. AutoLisp also has a built-in graphical user interface (GUI) mini- or domain-specific language (DSL), the Dialog Control Language, for creating modal dialog boxes with automated layout, within AutoCAD.[3]
AutoLISP was derived from an early version of XLISP, which was created by David Betz.[4] The language was introduced in AutoCAD Version 2.18 in January 1986, and continued to be enhanced in successive releases up to release 13 in February 1995. After that, its development was neglected by Autodesk in favor of more fashionable development environments like Visual Basic for Applications (VBA), .NET Framework, and ObjectARX. However, it has remained AutoCAD's main user customizing language.
Vital-LISP, a considerably enhanced version of AutoLISP including an integrated development environment (IDE), debugger, compiler, and ActiveX support, was developed and sold by third-party developer Basis Software. Vital LISP was a superset of the existing AutoLISP language that added VBA-like access to the AutoCAD object model, reactors (event handling for AutoCAD objects), general ActiveX support, and some other general Lisp functions. Autodesk purchased this, renamed it Visual LISP, and briefly sold it as an add-on to AutoCAD release 14 released in May 1997. It was incorporated into AutoCAD 2000 released in March 1999, as a replacement for AutoLISP. Since then, Autodesk has ceased major enhancements to Visual LISP and focused more effort on VBA and .NET, and C++. As of January 31, 2014[update], Autodesk ended support for VBA versions before 7.1, as part of a long-term process of changing from VBA to .NET for user customizing.[5][6]
AutoLISP has such a strong following that other computer-aided design (CAD) application vendors add it to their products. Bricscad, IntelliCAD, DraftSight and others have AutoLISP functionality, so that AutoLISP users can consider using them as an alternative to AutoCAD. Most development involving AutoLISP since AutoCAD 2000 is performed within Visual LISP since the original AutoLISP engine was replaced with the Visual LISP engine. There are thousands of utilities and applications that have been developed using AutoLISP or Visual LISP (distributed as LSP, FAS and VLX files).[7][8]
The above code defines a new function which generates an AutoCAD point object at a given point, with a one-line text object displaying the X and Y coordinates beside it. The name of the function includes a special prefix 'c:', which causes AutoCAD to recognize the function as a regular command. The user, upon typing 'pointlabel' at the AutoCAD command line, would be prompted to pick a point, either by typing the X and Y coordinates, or clicking a location in the drawing. The function would then place a marker at that point, and create a one-line text object next to it, containing the X and Y coordinates of the point expressed relative to the active User Coordinate System (UCS). The function requires no parameters, and contains one local variable ('pnt').
