Civil 3D – Part Builder Context Solution Part 2

Part Builder Context Solution Part 1

Ok, at last, the end of the journey.  We covered getting the model values out of an existing part.  The remaining issue lies with what to do now that we have a mandatory context added to the structure type.  Each time we create a new form of that structure type, that variable will be added to the Part XML file with all the other OEM required variables, such as “SHBTh”.  This would not be a problem except that we still cannot get our non-OEM variables forced into the part model parameters.

As you may recall from earlier discussions, adding an existing catalog parameter to the model parameters is verboten.  Consequently without some assistance, each new part would require yet another context parameter to be created in the list.  Eventually the list of copies of the same variables would be ridiculous.

What we did figure out is that we can link a required context parameter that is created in the part XML, to a parameter we used in the model parameters.

The basic outline is as follows:

  • Create the new part, using the proper structure type.
  • Validate the part and save it.
  • Create the model to its completion, adding any model parameters as needed.
  • Configure the Required Context Parameter to be a range or a list as desired.
  • Save the part and exit.
  • Edit the Part XML, and change the MODEL parameter’s equation to equal the Required Context Parameter.
  • Save the file and perform a catalog regen, and a catalog validation.
  • Check the part validation file to confirm all is well.  If it says there is a duplicate parameter, return to the Part XML, find the parameter definition that is a duplicate, and delete it so that only one parameter definition remains

Civil 3D – Revised Part Builder News

Ok, whew! We did it. After weeks of rework the custom parameters have been introduced and now stay put!  We have ranges and lists without error.

We….

I say we, because my new associate, David Neill, was working it at the same time. He suggested reintroducing an old issue into the new arrangement of edits. He was right.

David is the moderator of the LinkedIn site Civil 3D Part Builder.  He discusses these problems and many more.  If you are not part of the group, check it out. http://www.linkedin.com/groups?gid=1789091&trk=myg_ugrp_ovr

Autodesk

As many of you know I have been trying to get some input from the big dogs on this.  Indications were pointing to some poor bastard over there was being asked to answer a couple simple questions on my behalf.  While some of the conversations I had left me with the impression that Autodesk was employing the “is it worth our time?” evaluation, the official settlement is that they don’t have the ability to assist.  

The teams that were involved in that phase of the development have redistributed an in many cases have been laid off.  I know both of these issues to be absolutely true, not only in Civil, but in Manufacturing as well. 

Is it worth their time?  I don’t think so.  Really.  One popular professional said, “Insert a block an get on with it”.  After spending hundreds of hours pouring over these issues and answering questions, I agree.  Do I use the parts, Yes.  I already have them built.  I continue to build them for people for a fee.  However I still see very efficient designs using null structures every day.

Will they fix it in revision one day.  I think so.  But it may wait for a an architecture overhaul.  I really have no idea.

There are so few using that part of the software, that our pleas for help are often not heard.  I have stated that rather than address it, they simply ignore it. I can’t say that since I have been replied to about the issues.  What I can say is that commenting on the blogs is not enough.  You have a VAR, use them.  Who knows, they may comp you a year of subscription to get off their back.  Hmmm….

Autodesk has called the hand, and well it’s a push. They can’t help, but David and I will show you what we can to get it going.

So…..

I will explain the issues.  After that, if you need detailed help, you can email me.  Perhaps we can work something out.

Revision

This post was revised.  There was some contention that certain statements were not true.  Information I gathered indicated otherwise, but in the end, I cannot prove beyond a doubt hat I was not lied to.  Therefore this revision will correct a possible error.  An apology will follow in another post so that it will not be overlooked.

Civil 3D – Part Builder Comments Please

Ok, Part Builder is not easy. Evan with a tutorial and a workflow, it’s still not easy.

There is at least 1 person in the community that has had trouble with the series outcome.  I need to know how everyone did.

Good, Bad, and otherwise.  Please offer us your comments.

If there is a bug in the procedure, I need to get it fixed for everyone else.

Civil 3D – Part Builder Part 7

Back to Part Builder Part 6

In the last session we created the Structures in the Civil 3D environment.  In this session we will modify the configuration to add the slopes to a list, in order to change the structure to be consistent with the corridor side slope.

Open up Wingwall Sloped in Part Builder.  Since we have something that hopefully works, let’s save a new part.  This way we have both.  “If it aint broke, then don’t try and fix it”.  Let’s try Wingwall Variable Slope.

Pick the ‘Save As’ button on the toolbar. The ‘Save Part Family As…’ dialog will appear allowing us to change the Chapter, Part Name, and Part Description.  Leave the chapter as Inlet-Outlet-Custom, cut change the Name and Description to Wingwall Variable Slope.

Hit OK.

Right Click Size parameters and select Edit Configuration.

Backup your model

Before we begin, I seriously and strenuously suggest you back up your model.  Don’t do the saveas (which is fine I suppose), but instead use Windows explorer to copy the .DWG and .XML files to a backup location. The VISTA path to these items is C:\ProgramData\Autodesk\C3D 2009\enu\Pipes Catalog\US Imperial Structures\Inlet-Outlet-Custom\

Map the User Parameters to the Application

You may remember the parameters that were handed down when we verified the structure a few sessions ago.  These ‘handed down’ parameters are those that the application uses in it’s controls, and were assigned when we used the Part Configuration Undefined Bounding Shape.  Without these, the structure cannot be modified. These parameters are SHBTh, SHBW, and SVPC, which are the Thickness, Base Width, and the Vertical Pipe Clearance respectively. We used the user parameters (like bThick) to buffer our equations from the application controls, and to make it easier to understand when reading the parameter list.  When we go back to make changes, we can disconnect the application parameters, and toy with our user parameters, and then attach them when we are done.

Let’s set these values before we proceed farther.  Edit the Model Parameters as follows:

SHBTh = 6

SHBW = 24

SVPC = 24

Now we have given something solid to these values, we can map these to the user parameters we created.

bThick = SHBTh

bWidth = SHBW

Now that the parameters have been set, we need to change the bounding shape to be a box.  Right now, the application will only display the structure as a 3D solid, and many styles will not display

this.  To simplify your model in some cases, we need the bounding shape to be a box.

Back to Part 4

Ok, it’s been awhile.  Everyone knows I am studying for the test, but I feel so bad for all the people who have been emailing me about the series.  I will run through the ‘Homework’, and then complete the configuration session soon hereafter.

Homework Review

We left off with your homework, which was to transfer the Toe plane out, and complete the transitions. I’ll recap it as I run through.

Create the Toe Plane, Offset from the Right Plane a distance of ‘(bHeight-bThick)*bSlope’.  Insert the Anchors.

Don’t forget the model parameters for the offset distances.
