A & B Tip 5 – polyline areas

2 Replies

In this series of posts, I’ll be providing tips that show how to do something in both AutoCAD and BricsCAD, hence A & B.

The Series

The idea behind this series is to provide useful information for several sorts of reader:

  1. AutoCAD users.
  2. BricsCAD users.
  3. People in the process of transitioning from AutoCAD to BricsCAD and who need to know what to do differently (if anything).
  4. People considering transitioning from AutoCAD to BricsCAD and who want to know about the differences and similarities.

What area is that polyline?

There are several ways of determining the area enclosed by a polyline. This post goes through the various methods. You will also notice that in each of the methods, you get the length (perimeter) as a bonus.

Spoiler alert: the most efficient methods are at the bottom. There’s a one-click method in AutoCAD (it needs a little setting up first) and a zero-click method in BricsCAD.

LIST command in AutoCAD

The oldest method is the good old LIST command. Although this has been around for ever, here’s how it works in recent AutoCAD releases. Issue the LIST command, select the polyline, press Enter to finish the selection, and above your floating command line AutoCAD will show something like this:

If this display goes away and you want to see it again, hit F2 and it will return. If you have a docked command line, AutoCAD will display the information on the text screen, which it will then display:

If you have a floating command line but want to see the text screen rather than the over-the-command-line popup, you can switch to it using Ctrl+F2.

LIST command in BricsCAD

The command works in just the same way in BricsCAD as it does in AutoCAD with the docked command line.. The main differences are that the BricsCAD default interface has a docked command line, and that the text screen (called Prompt History in BricsCAD) is displayed even when using a floating command line.

If the text screen goes away or is obscured, you can restore it using the familiar-to-AutoCAD-oldtimers keystroke of F2 (not Ctrl+F2, which toggles the ribbon in BricsCAD).

Unit precision in BricsCAD

Another difference you might notice is that the only whole units are displayed. This is because BricsCAD respects the setting of DIMZIN when displaying values in the AREA command and AutoCAD doesn’t. In this drawing, DIMZIN is set to 8, which suppresses trailing zeroes. Because the area is exactly 448.0, BricsCAD displays it as 448. If DIMZIN is not set to suppress trailing zeroes, this doesn’t happen. If DIMZIN is set to 0, BricsCAD displays the area using the setting for linear units precision, LUPREC. If this is 4, the LIST command will display the area as 448.0000, as it does in AutoCAD.

This respect for DIMZIN applies in other places in BricsCAD too. For the remainder of this post I’ll have DIMZIN set to 0.

AREA command in AutoCAD

Another good old method is the AREA command. Issue the command, use the Object option and pick your polyline. You will be shown the area in two places as shown here:

AREA command in BricsCAD

The AREA command works similarly in BricsCAD. Although the options displayed indicate that the subcommand is Entity rather than Object, you can in fact use either E or O to initiate selection of an object. Unlike AutoCAD, the area is displayed in one place only, the command prompt area:

Note that the AREA command in both applications gives you more options, including adding together several areas.

Properties palette in AutoCAD

If you have the Properties palette visible (Ctrl+1 will toggle it on), you can simply select the polyline and the area will be displayed in the palette, thus:

Note that unlike the AutoCAD AREA command, the Properties palette does respect the value of DIMZIN. To display the trailing zeroes, first set DIMZIN to 0.

Properties palette in BricsAD

Using the Properties palette in BricsCAD is identical to AutoCAD. Here’s the display:

Quick Properties in AutoCAD

Quick Properties is a cursor-based cut-down version of the Properties palette. It’s not what you get when hovering, which is this:

What you want is Quick Properties, which you only get when you select an object, for example:

Unfortunately, Area is missing. It was there once upon a time, but there were performance problems so it was removed by default. However, you can add it back in. Invoke CUI and pick Quick Properties on the left. Scroll down on the right and pick Polyline.

Turn on Area (and Length if you want). Pick OK. Now see what happens when you select a polyline:

Note: in AutoCAD 2014 (and maybe others), the Area option was missing. There’s a workaround, but it’s a complex hack and well beyond the scope of this post.

Quad cursor in BricsCAD

The easiest way to find a polyline area in BricsCAD is just to hover over it. The Quad cursor will appear, giving you the information you need:

Alternatives

If you’re doing this regularly, it makes sense to automate it as much as possible. Depending what you want, menu macros might help. There are also various free LISP routines around that do this sort of thing, for example these by Lee Mac. If you have more specific requirements (e.g. automatic area label, export to CSV), then that’s the sort of thing I do for a living so feel free to get in touch.

A & B Tip 4 – turning on toolbars

In this series of posts, I’ll be providing tips that show how to do something in both AutoCAD and BricsCAD, hence A & B.

  2. BricsCAD users.

Your First Toolbar

If you are using a ribbon-based workspace, you may want to have some toolbars visible, too. There are several reasons you might want to do this. You might want some buttons to be consistently visible, no matter what the ribbon state. Although the QAT in AutoCAD provides some toolbar space, you might want more space than it offers. You might also want toolbar controls that are not available in the QAT; several of them only work in conventional toolbars. You might want the buttons in a different place, such as down one side or on a second screen.

If you have at least one toolbar visible already, things are easy. If you right-click on that toolbar, you will get a menu that allows you to turn on any other toolbar in the same customization group (CUI or CUIx file). Here it is in AutoCAD:

Here’s the equivalent in BricsCAD:

Note that in BricsCAD, the list of toolbars is one level down because the first-level right-click menu in BricsCAD gives you many more interface options.

What if the toolbar you want to turn on is in a different customization group? You can get at those easily enough by right-clicking on any blank (unused) area of a docked toolbar area. AutoCAD:

You can do the same in BricsCAD:

The difference with BricsCAD is that you don’t need to have a docked toolbar with spare space in it to access toolbars in different groups. They’re all available by right-clicking any toolbar button, docked or not.

That’s all easy enough, but what if you don’t have any toolbars visible? You’re stuck in a Catch-22 situation. You need a toolbar to click on to load a toolbar. How do you get that first toolbar loaded?

AutoCAD Interactive Method 1

The first trap to avoid in AutoCAD is using the TOOLBAR command. From Release 13 to AutoCAD 2005, that was useful. With the introduction of CUI files in 2006, the TOOLBAR command became a near-useless cut-down version of the CUI command.

Ignore that. If you’re going to use the CUI interface, use the whole thing. Enter the CUI command. In the top left pane, pick the workspace you want to change:

In the top right pane, pick Customize Workspace. In the left pane, expand the Toolbars part of the tree and turn on one of the toolbars:

Pick Done (top right) and OK (bottom). Your chosen toolbar will appear.

AutoCAD Interactive Method 2

If you have your pull-down menu bar turned on, you can get at the toolbars using the Tools menu as shown here:

You can turn on your pull-down menu bar by setting MENUBAR to 1.

Thanks to James Maeding for pointing that out.

BricsCAD Interactive Method

In BricsCAD, you can turn on toolbars interactively even if there are none visible, without having to deal with the CUI interface. Just right-click in any part of the ribbon, and you will see the same menu you get when right-clicking a toolbar area. That gives you access to all of the toolbars in all of the groups.

AutoCAD Command Line Method

If you want to use the command line to turn on a toolbar, you need to use the -TOOLBAR command (note the leading hyphen). You also need to know the name of the customization group and what the toolbar itself. One example is the Object_Snap toolbar within the ACAD group. The command line required is therefore:

-TOOLBAR ACAD.Object_Snap Show

To be sure this will work in all environments, I recommend you add the special characters _ and . thus:

_.-TOOLBAR ACAD.Object_Snap _Show

BricsCAD Command Line Method

In BricsCAD, you don’t need the leading hyphen in the TOOLBAR command (although you can use it if you like). The customization group and toolbar names will be different, but the syntax is the same. For example:

TOOLBAR BRICSCAD.TB_EntitySnaps Show

The recommended special characters also do the same job in BricsCAD:

_.-TOOLBAR BRICSCAD.TB_EntitySnaps _Show
