Can you really see through Transparent Commands?

While working on a support call today, I derived a solution for a customer that included using a Transparent Command. That got me to wondering how many people actually use the Transparent Commands in Civil 3D. I know that I did not use them very often in past employment engagements. It was not until I started teaching classes on Civil 3D that I fully understood the power of these commands and how they could help me work smarter and not harder.

For example, at one of my past jobs I worked with an older gentleman who was very close to retirement. He was fairly proficient with vanilla AutoCAD, but almost completely illiterate when it came to Civil 3D. I am not knocking the guy, because he was good at what he did. He just did not see the need to learn new software while being on the verge of retirement. A typical scenario for one of his projects was that I would take the survey data and create the surface and then hand the drawing off to him. He would complete the geometric design and give it back to me to produce profile drawings. When I created the profile drawings, I would have to plot them at an exaggerated scale and he would break out his old HP Calculator, complete with card reader, and design the profile on paper.

Then he would had the paper copies back to me and I would input the data into Civil 3D and finalize most of the design before handing it back for his review. At the time, I did not use the Transparent Commands very much because I did not understand what they were. So to input his design data, I would create a layout profile and get the PVI's close to their desired locations and elevations. Then I would open up the profile editor and hand correct the stations and elevations.

Does this sound familiar to you? Well, after a while I learned that there were commands in Civil 3D that run "inside" of other commands and allow us to input specific data in that command. Instead of having to get the PVI's close, I could have used the Profile Station Elevation transparent command to specifically enter the station and elevation of the PVI without having to go back and edit.

Which brings me back to today's case. The customer was working on a paving project. A contractor had constructed a leveling course and the customer had sent his crew out to collect profile elevations at an offset left and right of the center line. He then wanted to show those offsets in his profile view. I didn't want to have to try and create another surface and extract the data from the surface when we already had the point information in the drawing.

I began looking for a Transparent Command that would let me harness that point information and apply it in the profile view. To both the customer's satisfaction and mine I found the transparent command that would allow us to do just that. The command was Profile Station and Elevation from a Cogo Point, or 'SPE.

To use the command we went to the Ribbon and selected Profile Creation Tools from the Create Design panel. Once we entered the profile name in the dialog box and set our styles we invoked the Create Tangents command and then invoked the 'SPE transparent command. We selected the profile view in which to draw the profile and began to pick the point objects we wanted to see in the profile view. Then the steps were repeated for the opposite offset.

If you have not looked into using Transparent Commands, I encourage you to look into them. They can definitely help us work smarter and not harder!

A Couple of Pointers on Pipes

Have you ever needed to modify, or add part sizes to a structure in AutoCAD Civil 3D? Well, in this post I am going to cover how to modify and/or add part sizes in the parts catalog. The first thing I will tell you is that I am no expert in creating parts via the Part Builder in Civil 3D, but I have learned how to modify some of the parameters for existing parts to get the sizes that I need.

So, let's say, for instance, that you need a rectangular junction structure that measures 4' x 5' outside box dimensions and is traffic bearing (8" min wall thickness). How would we go about adding that part size to the current parts catalog? The first thing that we need to do is open up Part Builder. (Note: all of the Screen Captures in this post are from AutoCAD Civil 3D 2010.) The screen cap below shows where to find Part Builder on the Ribbon.

So we open Part Builder and on the Getting Started Dialog box we select what type of part we want to modify. In this case, I am choosing the rectangular structure with circular frame. Then we click on Modify Part Sizes as shown below.

After clicking on Modify Part Sizes Part Builder opens to show the parametric model of the structure and a list of the parameters used to define the structure.

On the right hand side of the Part Builder screen we see an image of the part. The part may or may not be drawn to any particular scale in this area. It really doesn't matter as we are going to assign the values for the parameters that we want anyway. On the left hand side we see a tree that contains listings of the parameters used to create the part along with definitions for geometry and constraints.

If you expand the Size Parameters node in the tree, you will see a list of the different parameters that make up the dimensions of the structure. Notice in the list that there are parameters for the Inside Width (SIW) and the Inside Length (SIL). These are the two parameters that we want to change for our new structure. We may also have to associate the two dimensions with the Wall Thickness (WTh). We can add or modify the appropriate parameters by right-clicking on Size Parameters and selecting edit values from the pop-up menu. This will open up the Edit Part Sizes dialog box.

Now remember, our intent here is to add a part size that will correspond to the desired dimensions of the structure we are calling for in our design, a 4'x5' box with 8 inch walls. We need to look at the available part sizes in the list to see if we need to add a size or modify an existing one. In this case click in the cell for SIW, then click on the Edit Sizes button (2nd from left at the top of the dialog box). This brings up another dialog box with all of the sizes that have been input for this parameter. Notice that there is not a 40 inch measurement, so we will have to add that one. Click the add button and a new field is created at the bottom of the list. Type in the value, in our case 40.0000. The unit of inches is the default here.

Next move over to the SIL column and repeat the above steps to add a par size of 52.0000 inches. Then check the WTh column and make sure that there is a 8" Wall thickness in the list. Next we need to look at how we are able to add a part with the dimensions that we just created to our parts list. We need to make sure that the wall thickness can be assigned to the new structure from the list of wall thicknesses that are in the list.

Click on the drop down in the middle of the top row of buttons in the dialog box. Then select Parameter Configuration from the list. The Data Storage row should be set to list for the three parameters that we have looked at above. Once this is done, click OK to close the dialog box and then click on the disk icon in the upper left hand corner of the Part Builder. This saves he new part parameters. Now we can close part builder. After closing Part Builder, we need to type "partcatalogregen" on the command line to update our part catalog with the new parameters. Now we edit our parts list and select the appropriate part sizes from the lists for SIW, SIL and WTh.

Another little tidbit that some users have seemed to forgotten. When showing a crossing pipe in a profile view, create a style with crossing pipe in the title and switch on the crossing components on the Profile tab in the view directions box on the display tab. This will cause the pipe to show a a section in the profile view.

Another Round with Dragged State Labels

Yesterday, while at a customer's office I noticed something that I had not seen before when it comes to dragged state labels, with points anyway. Take a look at the image below. I have created to random points in a drawing with the Point Marker Style for each set to Basic and the Point Label Styles are Point#-Elevation-Description and a style the I created with the coordinate information in it.

So, as you can see I have changed the colors of the text and added the coordinates. But then we looked at the dragged state for the point with the OOTB Point#-Elevation-Description Label Style. I was showing the customer how the label reacted when it was dragged out from the point. The customer asked the obvious question about the location of the leader in the dragged state and wanted the leader attached to the middle of the top line of text. This is where something interesting happened. When I changed the display of the dragged state from "As Composed" to "Stacked Text", the elements of the labels where rearranged. I had not noticed this in previous versions and that was probably because I typically used the Dragged State in the As Composed display mode.

I started digging in to see if I could deduce what had happened. The conclusion that I came to was that the Stacked Text display mode uses the order in which the label components are created. The next screen capture will show what I mean.

You will notice here that the component names are listed in the following order: Point Description, Point Number and Point Elev. And looking back at the label in a dragged state with the display mode set to "Stacked Text" we see that the label has been adjusted to match the order shown in the Label Style Composer.

To prove my theorem, I created a style the contained the same information and added the coordinate data. I was careful that I created the label components in the order that I wanted them to be displayed in the stacked text display mode. The result was as expected.

As you can see from the shot above, the the dragged state is what we would expect in a point label of this variety. Sometimes it is the little nuances of Civil 3D that make you go hhhmmmm.

Brought to You by the Fine Folks at Auotdesk Support

I was looking at different Civil 3D blogs a few weeks back and found one that is being written by the Civil 3D Support team at Autodesk. Not only do these folks do a bang-up job of helping all of us with our technical support questions, but they somehow find time in their busy schedules to blog too! The topics covered are very informative and take on a different perspective by approaching topics from the technical support standpoint. If you would like to check out their blog, click here.

These guys even find time to create the occasional video also. Here is one that covers just about anything you want to know about the Ribbon interface in AutoCAD Civil and Civil 3D 2010. Enjoy!

On another note, ALACAD will be on the road in the next few weeks presenting our Autodesk 2010 Discover Tour. Follow this link to our website and sign up for a city near you. Hope to see you there!
