You never know what might inspire a Tuesday Tip. This time, it came from my favorite streaming music service when it played David Bowie\u2019s 70s hit, Changes<\/em>. I immediately thought about the awesome AutoCAD command, CHSPACE, or Change Space. It\u2019s certainly worth discussing here, but I felt there wasn\u2019t enough meat there to write a full blog on it.<\/p>\n\n\n\n

This happens occasionally, and I\u2019ve been known to package them up into an AutoCAD Potpourri post. You can find the latest one here<\/a>. <\/p>\n\n\n\n

But how do I play off the song for the blog? Well, the answer came in the lyrics; there are four \u201cCh\u2019s\u201d before Changes<\/em> (is it in your head yet?) Fortunately, I know of three other AutoCAD Change commands that start with CH, so here we go!<\/p>\n\n\n\n

AutoCAD Change Commands #1:
Ch – CHSPACE<\/h2>\n\n\n\n

The main entry here gets top billing. Have you ever run into a situation where the text, dimensions, or other objects were drawn in the wrong space? As a Tuesday Tip reader, we\u2019ll assume it was someone else who made the mistake, and you\u2019re tasked with fixing it.<\/p>\n\n\n\n

This is where CHSPACE comes in. This handy command will move your objects from paper space to model space (or vice versa), all while preserving the scale of the objects. No need to redraw or rescale anything. CHSPACE does it all for you.<\/p>\n\n\n\n

Plus, it\u2019s an easy workflow. Issue the command (see the image below for the ribbon location, or just type it in). First of all, this only works from a layout tab. You can\u2019t use it in the Model Space tab. If you do make that mistake, it will remind you.<\/p>\n\n\n\n

You\u2019ll be prompted to select your desired objects. If they are currently in paper space, you\u2019ll be asked to select the viewport to send them into its model space.

If the objects are within an activated viewport (model space), CHSPACE will move them into paper space for you. And again, your scaling will be preserved.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

AutoCAD Change Commands #2:
Ch-Ch – CHANGE<\/h2>\n\n\n\n

Boy, this one goes back a long way. There was a time when changing an object\u2019s properties wasn\u2019t as easy as it is now. We had to use the CHANGE command, which does not appear in the ribbon and is only available from the command line.<\/p>\n\n\n\n

It prompts you to select your objects, then you can select or enter change points (the coordinates of the object \u2013 a most inefficient way of doing that), or you can specify Properties from either the command line or your dynamic input.<\/p>\n\n\n\n

Doing so will present you with a menu (see below) of the available properties you can change. Be aware that if you select something named, like Layer, you\u2019ll have to type it manually, so you\u2019ll probably need to memorize all of your layers and their proper spelling. Riiiight\u2026<\/p>\n\n\n\n

\"AutoCAD<\/a><\/figure>\n\n\n\n

Okay, I get it. There are many easier ways to accomplish this these days. However, it can come in handy if you\u2019re writing scripts or AutoLISP routines. In fact, I\u2019ve used it in the latter myself. Please note that if you do, you might want to turn off DYNPROMPT first.<\/p>\n\n\n\n

AutoCAD Change Commands #3:
Ch-Ch-Ch – CHPROP<\/h2>\n\n\n\n

The third \u201cCh\u201d command is a more direct approach to the previous Change command; it\u2019s called CHPROP, which means Change Prop(erties). And again, it\u2019s command line only. It doesn\u2019t have the option to change an object\u2019s coordinates, and it goes right to the Properties option instead. Streamlining your workflow by saving a few clicks? Who doesn\u2019t like that?<\/p>\n\n\n\n

You\u2019ll get the same menu as you see above, and it works the same way. Well, almost. Notice entry number two in the menu. For some reason, Elevation is not included in the CHPROP menu. I\u2019ll just leave you to ponder that strange omission. But hey, it made for a third \u201cCh\u201d entry.<\/p>\n\n\n\n

AutoCAD Change Commands #4:
Ch-Ch-Ch-Ch – CHURLS<\/h2>\n\n\n\n

Last but not least is a member of the AutoCAD All-Name<\/em> team. It is called CHURLS, and it stands for Change URL\u2019s. And check this out, you can find it in the menu. It\u2019s in the last panel of the Express Tools tab.<\/p>\n\n\n\n

\"CHURLS<\/a><\/figure>\n\n\n\n

Yes, it\u2019s an Express Tool, but like a lot of ET\u2019s it can come in quite handy. In today\u2019s world, it\u2019s not uncommon to attach hyperlinks to certain objects. And, like most things in AutoCAD, they sometimes need to be changed or edited. Granted, you could use the HYPERLINK command, but CHURLS acts as a shortcut for you.<\/p>\n\n\n\n

After launching the command, select your object with the attached URL. Hit enter, and you\u2019ll get the dialog as shown below, showing the current URL, already highlighted. I suggest already having the new URL on your clipboard so you can just paste it over the highlighted old one.<\/p>\n\n\n\n

\"CHURLS<\/a><\/figure>\n\n\n\n

That’s All Folks<\/h2>\n\n\n\n

I\u2019d like to thank the late David Bowie for inspiring this post. I was also lucky to know that AutoCAD has these four \u201cChange\u201d commands. Granted, a couple of them aren\u2019t too useful in today\u2019s world, but two of them are.<\/p>\n\n\n\n

So arm yourself with these CH-powered changes, and make your drawings Hunky Dory<\/em>** again. (** The name of the 1971 album that Changes<\/em> was on.)<\/p>\n\n\n\n

You\u2019ll also be glad to know that no AutoCAD command begins with \u201cHUN.\u201c<\/p>\n\n\n\n
