Able2Extract PDF Converter Review

Often times in the world of CAD and engineering we find ourselves with a PDF document that we wish we could modify but can't. The solution used to be we had to recreate the document in its native program from scratch. This was especially painful if we were dealing with a complicated AutoCAD drawing in PDF format. Luckily, those days are long gone. Investintech has created the best PDF conversion software around and one of the best benefits is being able to convert those pesky PDFs back into DWG or DXF files. Not  only does it convert PDF to AutoCAD, it also does the whole range of Office products including Excel, Word, PPT, and others. How awesome is that? It's easy to use and there are Windows, Mac, and Linux versions available.

You can see some document conversion examples on their website as well as a link to download a free trial here: http://www.investintech.com/able2extract.html

How to Convert PDF to AutoCAD

One question many CAD users ask is if there is an easy way to convert PDF to AutoCAD format. Well, now there is an easy, and best of all, FREE solution for you. PDFAutoCAD is a free PDF to DWG  and DXF conversion for AutoCAD-designed PDFs.

Some of its distinct features are:

• High quality conversions with lines, arcs, scale presets and texts preserved, and no need for further touch-ups.
• Files of up to 40MB can be uploaded and converted quickly.
• All uploaded user data, including emails, is deleted in accordance with their privacy policy.
• Everything is free - they support themselves via ads on the homepage (please, don’t be confused by them).

I've used this site myself and find it very useful. Check it out here.

3D Boat Design Software

I recently found a nice 3D boat design software to help you design anything that floats. If you have ever wanted to design a boat yourself then this is the program for you. 3DBoatDesign is a versatile CAD software package that is easy to use yet also powerful at the same time. Some feature of 3DBoatDesign include enhanced hydrostatic calculations, easy 3d scaling, rotating, and moving, hull sculptor, resistance calculations and more!

3DBoatDesign is to boats as NoLimits Simulator is to roller coasters - simply the best available software to everyday consumers and affordable too!

Drafting and Dimensioning in Solid Edge Tutorial

Ally PLM has created another wonderful Lunch Bytes Solid Edge video tutorial. This time the topic they cover is Solid Edge drafting, dimensioning, and annotation tips and tricks. More detailed topics include how to create drawings in Solid Edge, how to create a quicksheet template, how to add different views, how to create dimensions and annotations, how to make sheet metal callouts, and more. Watch this awesome Solid Edge tutorial below:

Android Application Programming Basics

Today I’m going to share a few of my notes about Android Application programming basics. Recently I’ve been trying to learn how to program Android applications. This post is not directly related to CAD but I will hopefully one day be creating some Android applications for CAD users.

Android Programming Acronyms

• SDK = software development kit
• DP = density pixels
• IDE = Integrated Development Environment
• UI = User Interface

Android apps are written in Java. I think it’s much harder to learn than writing macros for CATIA V5. When you write a macro, you can type up the code in a simple text editor and it is read top to bottom like a book. When writing code for Android applications, code must be inserted into at least three different locations within the Eclipse IDE software.

Pages or screens in Android apps are known as Activities. An Intent is a communicator with another application and you use it to change screens. To create a new activity right click on package: New>Class. Give it a name and set Super class as Activity, which will be a java file. Each activity needs a layout file (.xml) created by going to New>Android xml. Name it file_name.xml. Xml is a way to organize information with structure (as opposed to just using a text file). The xml file is used to organize the layout and properties of all the text, input boxes, buttons, images, etc. Buttons use a method called OnClickListener.

Alright, that might have sounded confusing to you, especially if you’ve never programmed before, so I’m going to leave it at that for now. Would you like to learn more about Android application programming? Please let me know and I will write more detailed posts. I’ve recently created two Android applications and they are available in the Google Play store for Free here.

In your opinion, what are the best CAD apps out there?

CATIA Lego Training Download

I’ve long looked for a good LEGO CAD program and today I’ve finally found one. John B Cearns, founder and

owner of Solid Engineering Solutions, has created an outstanding exercise to help students learn how to use CATIA’s Assembly Design workbench while being super fun at the same time.

While building the Lego model you’ll learn how to use catalogs in CATIA to create different Lego blocks in 3D. Not all the parts required to make the Four Wheeler and Rebel Wrecker are present in the CATParts folder. There are 72 parts missing from this folder but they have provided 12 tabulated parts for you to use to easily create the missing 72 parts. Step by step instructions are provided in the documentation for both sets.  The Four Wheeler contains 102 different parts and the total parts are 338. The Rebel Wrecker contains 123 different parts and the total parts are 468.

The free download contains all instructions necessary to assemble the Four Wheel and Rebel Wrecker. Or, if you just want to build the physical Lego sets you could just do that as well using these instructions. Get them here:

After you have created these two CATProduct models, there is a wealth of Kinematics joints you can perform on them: Revolute Joint, Cylindrical Joint, Spherical Joint, Rigid Joint, Universal Joint, Gear Joint, Cable Joint, and Rack Joint. The Lego parts also use a relation law created by a Multiple Value User Parameter to define the color: PartBody.Color = PartBodyColor.

This exercise is a great example if you want to use CATIA or other CAD software as a Lego design software. Many different bricks can be created from the template of a few using catalogs. All around, I highly recommend checking out this tutorial because, as I said, it is a lot of fun and very educational too (and it's free)!

Please note: CATIA V5 R19 is required.

Default Text Sizes in CATIA V5

How do you change the default tree text size in CATIA?

To change the default size of the text in the specification tree in CATIA V5, click on the tree. This will allow you to first set the size of the tree text to how you want it by zooming in or out. Once satisfied, instead of clicking on the tree again click on the axis system in the lower right hand corner of the screen. This should change the default size of the specification tree, even if you should close CATIA and open it again the text size should remain the same. 

How do you change the compass size in CATIA V5?

 

Another common question is how to change the size of the compass. I recently just switched over my PC to Windows 7 OS and the compass is smaller now than it was while I was running Windows XP. In addition to this, when I right click on so geometry in the spec tree and open the Parents and Children window in CATIA the default text size is so small I can't easily read it. Thus, I have to zoom in on it every single time which is really annoying and wastes valuable time (I'm a CAD engineer and am always striving for the most efficient way to do things). There does not appear to be an option under Tools > Options to change this setting. The best answer I could find involves editing the CATIA Environment file (env.txt) as so:

CATWidthMMOfScreen= 340 which is the screen width value in millimeters => measured on your screen.
CATHeightMMOfScreen= 200, the screen height value in millimeters => measured on your screen.
CATWidthPixelOfScreen= 1920, the horizontal screen resolution set in your computer display properties panel.
CATHeightPixelOfScreen=1200 is the vertical screen resolution set in your computer display properties panel.

The location of the CATIA environment file depends on how you or your administrator have set it up. Listed below are the default CATEnv file locations: 

Windows XP:

C:\Documents and Settings\All Users\Application Data\DassaultSystemes\CATEnv
C:\Documents and Settings\username\Application Data\DassaultSystemes\CATEnv

Windows 7:

C:\ProgramData\DassaultSystemes\CATEnv
C:\Users\username\AppData\Roaming\DassaultSystemes\CATEnv
