CAD Panacea tip – startup files in BricsCAD

3 Replies

One of the things that might initially baffle a CAD Manager or power user when investigating switching from AutoCAD to BricsCAD is how to set up the startup routines. Head over to CAD Panacea for R.K. McSwain’s concise, handy description of how to do it.

Due to BricsCAD’s high level of compatibility, you can maintain a common folder or set of folders containing LISP and other custom files for both applications. That way, you don’t need to do double maintenance during the transition period. I’ve done this successfully in a highly complex custom environment. Some code and other adjustments were required in places, but all but a handful of my hundreds of AutoCAD LISP files worked as-is in BricsCAD with zero effort.

Having added your AutoCAD custom folder(s) to BricsCAD’s search path, I suggest you make a common startup LISP file (e.g. rename your old acaddoc.lsp to something like CADStartupDoc.lsp) and have tiny stub startup LISP files for each application (acaddoc.lsp and on_doc_load.lsp) that each loads the common startup file.

acaddoc.lsp contents:
(load "CADStartupDoc")

on_doc_load.lsp contents:
(load "CADStartupDoc")

You can add error checking and messaging if you like, but if you have control of your environment you probably won’t even need that. If you find you do need any application-specific code, you can just add it or load it from the acaddoc.lsp or on_doc_load.lsp stubs as appropriate.

CAD-related Twitter exchange of the year

In a Twitter post (now deleted), the AutoCAD twitter account asks us to submit our feature ideas for AutoCAD, and links to the Autodesk Ideas Page:

Just one problem. As R.K. McSwain points out in his reply, the Ideas Page has no section for AutoCAD. There should be one, and should have been one for years, but there isn’t. That tells you all you need to know about how the level of concern Autodesk has about AutoCAD’s future development.

Here’s the exchange in all its glory:

Oops.

The big Bricsys interview 10 – platforms

Leave a reply

This is one of a series of posts covering an extensive interview with Bricsys CEO Erik De Keyser and COO Mark Van Den Bergh.

In this post, R.K. McSwain asks about BricsCAD running on three different platforms. Erik explains why BricsCAD for Mac (and Linux) is so much more complete than AutoCAD for Mac, which has more holes than a block of Swiss cheese.

R.K.: Do all three platforms (Windows, Linux, Mac) contain the same functionality?

Erik: Yes. Sometimes it’s a bit hard with the Mac to bring it along but so far, so good. The only problem sometimes is in the APIs.

We are using wxWidgets and not the Microsoft classes. This gives us the ability, with the same source code more or less, to serve Mac, Linux and Windows. By far Windows is the most important one. By history, all the applications are on Windows, because AutoCAD was only Windows. What we have as APIs, and the most important ones are BRX and .NET. If you want to port an application to Mac, it means our API must support that as well. BRX is doing that for 90 to 95%; there are a couple of functions that only work on Windows. For most of the applications, they can port their application to Linux or the Mac without any problems.

Steve: And you support the Visual LISP COM functions as well, right?

Mark: Yes, we cover them and they are also available on Mac and Linux.

Steve: You have a solution there that Autodesk doesn’t, which gives us the strange situation that BricsCAD for Mac is more AutoCAD-compatible than AutoCAD for Mac.

R.K.: AutoCAD for Mac leaves a lot of holes.

Erik: That’s because they rewrote the whole interface for Cocoa, and we didn’t. We are using one code base. You can be more Catholic than the Pope, yeah? If you rewrite AutoCAD completely for the Mac, the result is many holes, no applications possible, it doesn’t help anybody. We’re better off being pragmatic and doing it the way we did it.

Still, we must say that applications availability for Mac and Linux is not much. That has to do with 95% of our sales being on Windows. We expect that might change for BIM, because more architects are Mac users, partly because the first version of ArchiCAD was on Mac, Vectorworks is, so it’s really an Architect’s machine. We expect that maybe for BIM, it might change and we might sell more versions on the Mac.

Steve: Autodesk doesn’t have a competitor there, does it?

Erik: No, absolutely not.

Mark: I should mention that all of our keys are cross-platform. So when you buy a key, you can run them all. So every time you on decide to run on Mac and later on you decide to switch it to Windows, we don’t have any problem. You can switch whenever you want, from one to the other, on to Linux if you want.

Erik: Again, choice. It’s up to the users.
