Inserting a Sketch Picture in SolidWorks

1.                  Save the image as a jpeg in the folder where you wish to save the SolidWorks part file.  Otherwise the image will not be referenced by the part file
2.                  Open a part file and save it to folder containing the image. Create a sketch on the top plane for example
3.                  Go to Tools/Sketch Tools/Sketch Picture
4.                  Browse to the folder containing the image (I have saved the image as a jpeg). Select the image and ‘Open’.
5.                  The image will be inserted with one corner on the origin. 
In the Property Manager you can edit the position of the image relative to the Origin or its inclination using the first three dialogue boxes

 You can adjust the size of the image by editing the dimensions in the 4th and 5th dialogue boxes

6.                  Confirm ‘Sketch Picture’

Problems Filleting and Chamfering in SketchUp

Coming from a background of using SolidWorks the Fillet and Chamfer tools would be regularly used in the designing and modeling of products. But since starting to use SketchUp, I found that the absence of this two features made it difficult and cumbersome to create projects. There are of course ways around it but time and patience, run out fast. So on searching through the vast number of plugin's available in SketchUp, I discovered RoundCorner created by Fredo6.

This plugin is a must have for all SketchUp users and is pretty straight forward to use and install. Indeed Fredo6 has a number of very useful plugin's developed which are worth a look at.

RoundCorner is a simple tool with a few (sort of) complicated settings. At its simplest, here’s what it does:

Click on an icon in the Round Corner toolbar to activate one of the “modes”: Round, Sharp or Bevel.
RoundCorner can make rounded edges with round or sharp corners. It can also make bevels (far right).

Pick the edges you want to round by clicking them. Click again to deselect an edge. You can also click a face to select all of its edges, or a vertex (where endpoints meet) to select its connected edges.

Pick edges, faces or vertices.

Press Tab on your keyboard to bring up the Parameters dialog box. Enter an offset distance and the number of facets (segments) your new rounded edges should have. Click OK to close the dialog box.

Use the Parameters dialog box to specify an offset and a number of sides. Using a small number of sides yields more usable models.

Increasing the number of sides on your rounded corners increases your face count exponentially.

When you're ready, click somewhere in empty space to run the script.

So many settings

There are plenty of settings in the toolbar that appears in your modeling window when you activate one of the tools; take a look at the plugin’s handy documentation to see what everything does (Tools > Fredo6 Collection > RoundCorner > Documentation...)

Details, details
  • You can download RoundCorner (as well as all of Fredo6's other plugins) from theRuby Library Depot.
  • Fredo6 makes his plug-ins available as donationware, meaning that they're free to download and use, but that payment is always gladly accepted. I highly encourage you to support his efforts.
  • This SketchUcation thread provides good discussion and examples.
  • This Pushpull Bar post is helpful, too.
  • So is this video that Fredo6 made.
  • RoundCorner works on both Macs and PCs.
  1. Unzip the folder you downloaded.
  2. Move both things inside that folder (another folder called ROUNDCORNER_Dir_xx and a file called ZLoader_Roundcorner.rb) into your Plugins folder.
  3. Make sure you have the latest version of LibFredo6 installed, too (there should be a link to it on the same download page.) It contains things that all of Fredo6’s scripts need to work. Download and unzip it, then move its contents (a folder called LIBFREDO6_Dir_xx and a file called LibFredo6.rb) into your Plugins folder.
  4. Restart SketchUp.
  5. Choose View > Tool Palettes > Round Corner to activate the tool.

Galway Education Centre to give schools Google Sketchup Pro for FREE

The Galway Education Centre has signed a contract with Google to distribute 3D modelling application Google Sketchup Pro for free to all interested Irish primary and secondary schools.

The application lets students create 3D models from scratch or by using existing data. They can import drawings, photos, aerial images and other data and can then use the application’s tools to create 3D models. Sketchup can be used design and create project for Technical Graphics, Materials Technology Wood, Construction Studies and Technology at second level. These design can be then present in a ranges of formats in a portfolio for examination and assessment. 

Google offers an extensive range of online video tutorials in which users can develop an understanding of the software from beginning to end.

Galway Education Centre is distributing the software FREE to all schools, simply contact the Education Centre for details. This is an excellent tool in the development of visual understanding of objects at second level and Galway Education Centre and Bernard Kirk must be commended for their innovation in providing this to schools.
