The H-Factor

Today we got a drawing that would crash because the designer had duplicate pipes right on top of each other. There is a quick way to check for and fix this.

The AutoCAD Express command OVERKILL will delete duplicate objects, among other things. Either type in OVERKILL at the command prompt or pick it from Express->Modify->Delete Duplicate Objects.

After you select your objects, this brings up the following dialog box:

Notice that you can have it ignore certain settings when deciding if objects are identical. I can't think of any situations right off the top of my head where I might use this, but no doubt there are some you might think of.

I don't recommend checking any of these options, so uncheck them all.

Play around with it and feel free to report anything you have learned about it.

If you are still on AutoCAD 2000, it’s way past time to get off of it and upgrade. That goes for 2000i and 2002, too.

We are adding new features and functionality to the current versions of HydraCAD (V43, 44 and 45) and some of these features do not translate back to V42 (2000).

One of these is the ability to color code sloping pipe, a feature which is found inside the Size Pipe dialog box. Drawings sized using V43 or newer and then opened with V42 will get a fixnump error when attempting to size pipe in that version.

The solution to this is to start a new drawing in V42 and insert the broken drawing into it. The real solution is to stop using V42.

Almost daily I get calls from customers saying that when they type in Open they don't get a dialog box but a command line asking for a file name, or their pipe sizes come in with the word -LENGTH- instead fo the actual length. AutoCAD variables are usually at fault.

Here are the most common offenders and their correct settings for this and similar problems.

The following list is taken from our Frequently Asked Questions page in the Updates and Support area of our website.

We hear from a number of customers who have trouble with one of three related things in AutoCAD 2006:

1. A regen causes machine to lock up
2. Switching between layout tabs causes machine to lock up
3. Previewing a plot causes machine to lock up

While these three things are not limited to the 2006 version of AutoCAD, they do seem more prevalent on that release. Inevitably these problems all point to the graphics card. Either there is not enough memory on it or more likely the card is not compatible with AutoCAD 2006 or later.

An easy way to verify if your card is okay with AutoCAD is to visit their Graphics Hardware List and look up your card to see if it is fully approved. If it is not approved then I recommend that you get a new graphics card. Which one? any one that is Autodesk Certified will do you well. The graphics card we are using on our newer machines is the NVIDIA Quadro FX 1400 and yes, it does work well.

I just signed up for classes at Autodesk University, held once again this year in Las Vegas. This is an annual four day orgy in all things AutoCAD and we send 3-5 people each year to brush up on programming skills and learn new features about Autodesk programs and how to properly use them. You can expect to see a few posts about those after this year’s AU which always takes place the week right after Thankgiving.

AU is open to anyone willing to spend the time and money to be there. Each year over 3000 programmers, users and management types go to see what is up with technology, the internet and new releases. You can choose from a vast array of courses on a number of different ‘tracks’. There are no tests (unless you are trying to get certification, which you can) but there is a lot of information that is taught and extensive handouts are given.

You may not know this, but if you are on the Autodesk Subscription plan then you are able to access the handouts and courseware electronically after AU has concluded. You can access the AU 2005 courseware now at Autodesk Subscription Site

Many people I know have a bunch of AutoCAD seats in their company and get pretty frustrated trying to keep them straight. AutoCAD has two ways to make this easier:

First is a Network License. With this you can install, say, a five user networked AutoCAD on a server and users can ‘check-out’ a copy as they need it. When they close AutoCAD the copy is returned to the server for use by someone else. Since each of these seats costs more than their stand alone counterparts, this is best only when you might have eight or nine sometimes-users. If each of your users is going to be using a license full time, then this is not for you.

Second is a Multi-Seat Single Serial Number License. This is ideal when you or your IT person is tired of keeping track of 20+ serial numbers. All your existing seats are consolidated into one copy of the AutoCAD media with one serial number. Purchasing this option costs the same as if you bought individual single station seats.

The great thing about this second option is that when you need more seats, we can just add them to your existing serial number and you will not have to wait for the new media from us or keep track of more CDs on your end. When a user installs the new seat, they will be able to tap into that pool of new
authorizations. Voila!

In other news since there are now 9, 12, 53, 100+ planets in our solar system, maybe we need a better way to manage those…
