Inventor – Creative Design With Autodesk Inventor 2010/2011™

image I am very pleased to announce that I am working with Dennis Jeffrey at Tekni!

He has assembled a team of experts to create the new Web Based training series titled Creative Design with Autodesk Inventor 2010.  Many training programs just ‘throw the information at you’; we (authors)  don’t want a repeat of the status quo, non-intuitive and inflexible methods sometimes employed.  We are developing a complete training course focused on real world application, and a start to finish methodology.

The Creative Series is designed to give the student a better sense of direction and confidence. Students work at their own pace and receive mentoring when needed.  Furthermore we have spent a great deal of time focusing the lessons around solid ‘real world’ design practice. Details, notes, and exercises detail why certain steps are counter-productive, and what can be done to create more efficient and flexible designs.  As the students move from one lesson to the next, they will have developed an awareness of some things that could go wrong in the current lesson, and are conscious of these while studying the steps.  This allows the student to gain more self-confidence as they verify that their cultivated concerns were substantiated. 

While nothing can replace real world practice, this course was designed to put the student a step ahead of the basic (and some advanced) problems that traditional lessons can’t identify.  The result is with designers and engineers that have more self confidence about applying solid design practice in their workplace, what to do when something does go wrong, and how to use that knowledge in an adaptive way at your company.

I have spent numerous days on each of my segments in the series, going through each portion and applying the lesson to the examples provided.  I focused my troubleshooting skills on creating powerful examples that work well and are easily adaptable.  Bulleted lists of commonly known issues and new insights are furnished in the lesson so that the student gets the benefit of past and present research and adaptations.

The Creative Design series is scheduled to be available by the end of 2009, but we will begin releasing packaged segments earlier.  Check in with us in the mean time as things become available.

Civil 3D – Rotate/Translate selection of Points

In Land Desktop rotating a selection of points was a piece of cake.  Well….if you had Lisp code, and we had tons of it.  Since writing about solutions (and actually solving them) takes more time that writing code, my group doesn’t really have a great deal of new code turned out, and use mostly native AutoCAD/Civil commands and features.  I’d love to finish .NET’ing all my old LISP, but I just don’t have the time and money.  I tried to get dirt on fellow coders, but coercion and blackmail will not work on Christopher (he is a clean cu chap), so I guess I am stuck with work-arounds.

The situation in the image below is nothing new to anyone dealing with Point data coming in, especially when it is fill for an existing design.  The backsight is wrong.

If you don’t have a survey network loaded, then you may be scratching your head.  There are no tools to select a group of points and modify them using standard AutoCAD tools.  You can get a group, but you still can’t affect a group with the touchy feely interface that you understand.


Identify the group of points that are wrong, and make a Point Group, and position it at the top of the Group List.  Set both of it’s styles to be Standard.  Then take the ‘All Points’ Group, and send it just below the new Group.  Set it’s styles to be ‘<none>’ for both styles.  No big Mystery here, just filtering out the problem points.

Now the key is how you have organized your Object Layers.  Mine are all “PNT-*”.  So I go to the command line and lock all layers, and unlock the Point layers. “-la lo * unl pnt-*”

When I window the area, only the visible points will be selected.  All the rest of the entities are locked by layer.  Here a simple rotate by reference command gets me going.


We used to have a really nice tool written by Dexter Lundy, that selected LDD Points by Description, Point Range, and Elevation Range.  That will probably be the next tool I recode.  It wasn’t possible to get it in 2007 when I last investigated it, but I believe it would be a cinch to get working now…..hint hint.
