Silhouette curves are commonly used for generating parting lines for plastic part design, or for use in multi-body part design.
A silhouette curve represents the contour of the model relative to a specific pull direction. The curve can include both the inner and outer design model boundaries, as shown below. The curve can be best explained by imagining a light shining on the model. The curve is placed wherever there is a silhouette.
The models shown below show two examples of silhouette curves created on similar models. In the left model, the silhouette curve feature creates two curves because the straight faces were excluded, and in the right model, it creates a single curve around the entire model because nothing was excluded.
You can use the mouse wheel to move around the scene. The movement is based on a pivot point, as shown in Figure 1–21.
Note that the mouse wheel functionality changes depending on the command you are currently using. To Zoom, Pan, or Orbit a model, in the Quick Access Toolbar or Navigation Bar, click(Select), and then use the mouse wheel as follows:
• Zoom - Scroll the mouse wheel up to zoom in and down to zoom out. • Pan - Hold the mouse wheel and then move the mouse to pan. • Orbit - Hold <Shift> and the mouse wheel, and then move the mouse to orbit around the scene.
• When you zoom, the current location of the cursor is the pivot point. • Pan and Orbit use the pivot point defined by the most recent zoom.
Autodesk Moldflow Synergy, also known as just Synergy, is the graphical user interface for Autodesk Moldflow Insight.
It provides a quick, simple method of preparing, running and post-processing an analysis for a model.
It also has fast, easy-to-use wizards for creating multiple cavities, runner systems, cooling circuits, mold boundaries and inserts.
Included with Autodesk Moldflow Synergy is a material searching capability for the extensive material database.
Material creation tools exist to import, change/modify and create materials to be used for any Autodesk Moldflow Insight analysis.
To communicate your results with colleagues, Autodesk Moldflow Insight has a report generation facility that creates reports. You can customize the reports to contain any of the results derived from an analysis. The reports can contain images of the part(s) analyzed, including any of the animated results. One report can contain results from any number of analyses or studies.
Solid View creates a viewport and several layers. The viewport is placed on the Vports layer, which is created if required. Each viewport is given a name. This name is used to create four layers per viewport: <name>-DIM (dimensions), <name>-HAT (hatching), <name>-HID (hidden lines), and <name>-VIS (visible lines).
Do not put anything else on these layers (except for the layer Dimensions), because Solid Drawing automatically deletes and updates the information stored on them.
Change the linetype for the -HID layers so that they display with hidden lines, as shown here:
You can change the color of any of the layers as required.
Hatching created in sectional views uses the current values set in the Hatch command. Double-click on the hatching to modify it once it is in the drawing.
I recently spent some time in the 3D sketch environment (not something that I do often). It has been a while; definitely before the Inventor 2017 release. I used to find it tough to sketch and know what plane I was on, and I mostly only used the Project to Curve option. I wanted to share some of the cool features that I found and will certainly use to “control” my 3D sketches.
There are the (Ortho Mode) and (Snap Object) options in the Status bar at the bottom of the graphics window that enable you to better control how the entities are sketched. With Ortho Mode enabled, you can restrict sketching to the X, Y, and Z planes. With Snap Object enabled, you can snap new entities to existing ones. Nice! Definitely makes sketching entities more accurate.
Additional status bar options are available to enable/disable dynamic dimensioning, inferring constraints, or to show/hide constraints.
There is more 3D sketching control added with the addition of options (shortcut menu) that help you align and reorient the model to accurately sketch your entities.
Use Align to Plane align to sketching triad to a plane.
Use the Orient Z and Orient to World to reorient the sketching triad to a custom Z direction or to the world coordinate system.
Use Snap Intersection to snap an entity to the intersection of entities. Ortho Mode must be enabled.
You might be thinking that I am a bit of control freak at this point (you possibly are correct), but there is still more to get excited about. Constraints! Yup... there are more constraints to use. In addition to the pre-2017 constraints, there are options to constrain to a planar face, constrain parallel with the X, Y, or Z axis, or constrain with the XY, YZ, or XZ planes. The equal constraint has also been added.
You can copy and paste sketches in the same sketch or in a different one. Then I can use the 3D transform tool to manipulate its location in the sketch. It uses the familiar triad to translate (along an axis or in a plane) or rotate.
Lastly, I love the new sketch tool that enables me to sketch directly on a curved face. Awesome!
I certainly encourage you to look at how this environment has improved over the last few releases. You might find a lot more use for 3D sketches and all the “control” it offers.
In the webcast (which you can view here) I talked about how we customized Revit to work for landscape architecture where the base elements were limited or, in one case, needed a new element, to show landscape specific information. The customization process we used is beyond the scope of the fundamentals level class but all the methods I used are covered in Autodesk Revit 2017 BIM Management: Template and Family Creation.
The subtitle of the webcast was “Planting Components, Planting Areas, and Planting Schedules” so, you can see where the customization was most needed – all around plants.
Follow-up Q & A
As always, we had a lot of good questions for follow-up. Here are a recap of the questions along with my answers:
Q. Will this info apply to REVIT LT 2017?
A. Much of what is covered in the training guide can be used with Revit LT. There are some limitations including Shaped Edited floors, which are used for creating hardscape and area plantings with multiple slopes.
Q. Are there exercises in the book on how to calculate the volume of dirt for the above ground planting areas?
Q. I've seen in many projects that utilize the RPC trees (in a lot of quantity) becoming fairly heavy and hard to move around in... Is this still an issue, have you seen this in some of your larger projects?
A. Yes, RPC (Rich Photorealistic Content) components can become cumbersome. In this case you might want to place 2D elements where having 3D elements is not needed. For example, we used a 2D bamboo component in some areas in the practices. These components can hold all the same information as the 3D components and show up correctly in the schedules.
Q. Does Revit have any plans to further develop plant libraries that come 'out of the box' to help users avoid the daunting task of building up a complete plant library from scratch? Seems like that would be a deal breaker for many.
A. I haven’t heard about anything yet and I do understand that this is a big issue. My recommendation as you are starting out is to create the plant libraries you need as you need them. This way you will build your library as you build the number of projects in Revit. Of course, if you have someone hanging around doing nothing…
Q. After planting areas have been placed, how do they appear on sheets? We've only seen them in views thus far, as color blocks.
A. For the webcast I was showing the color blocks because they look pretty:) You can have patterns applied as shown below. These patterns are typically setup in the material.
If they are not showing it could be that the Fill Pattern Graphics for the view have been turned off. You can fix that in the Visibility/Graphics Overrides dialog box as shown below.
This turns on the patterns for all floors – not just the planting floors. You can turn off the Surface Patterns of individual floors by using Override Graphics in Views>By Element...
Q. If the LIM Project is merged with an Architects Revit Project, can the floors be filtered or will they all show up in the project browser?
(LIM= Landscape Information Modeling – this is a term I used in the webcast.)
A. When you link Revit projects with each other you can control the project categories separately.
I interpreted the term floors in this question to be levels (rather than hardscape or planting floors) because this is what shows in the Project Browser. In the Autodesk Revit 2017 for Landscape Architecture training guide we cover how to link Revit models and how to copy and monitor levels between the projects. A more advanced use of Visibility/Graphic Overrides is to control the visibility of categories of elements in the Revit Links tab. This is covered in the Autodesk Revit 2017 Collaboration Tools training guide where we go more in-depth of how to use linking in projects.
Q. Regarding the spacing on boxwood floor planting, she changed the on center from 6 to 9 – I’m a bit confused on subject.
A. Sorry about the confusion – I probably went a bit too fast! In one example I showed that we created a custom instance parameter that lists typical spacing (in inches) as shown below. When you select from the list it establishes the Analysis Results that are then used in the schedules to tell you how many plants are needed for a specific planting area based on the spacing.
Q. You mention the custom content created for the book, but the book does not cover how to create the custom content or schedules.
A. Yes, a lot of the custom content we created for the book (and covered in this webcast) is beyond the scope of a fundamentals level training guide. If you are going to be creating the content and setting up the schedules and custom parameters for your company, you will also need the information covered in Autodesk Revit 2017 BIM Management: Template and Family Creation. There are no practices in this book now that are geared specifically to Landscape design but the methods are the same no matter what schedule you are building.
Isolines are lines drawn on a curved surface to indicate that the surface exists. The Isolines variable controls how many isolines display on curved solids. The default value is 4. A larger number creates a more tightly curved object, as shown here.
Silhouette edges (Dispsilh) are lines that indicate where a curved surface disappears from sight, as shown here.
The Isolines and Dispsilh variables affect the plotting of shapes when the lines are hidden. Facet resolution (Facetres) sets the smoothness of shaded and rendered objects, and objects with hidden lines removed, as shown here.
When you are starting a simulation project the first question you need to ask yourself: is this an existing part? The answer to such question defines the procedure you are going to follow to complete the simulation project.
Construction entities are used as a reference and do not create solid geometry. It is common to use construction lines in sketching to indicate that arcs or circles lie along the same line or to indicate the midpoint of a line. An example of a use for construction circles is shown here:
To sketch a construction entity, in the Format panel, click (Construction) and sketch an entity (e.g., line, arc, etc.). To toggle an already sketched entity from solid to construction (or vice versa), select the entity and click the icon again.
The AutoCAD software has two methods of controlling light intensity: photometric and generic. These can be set in the Units dialog box (usually in a template file) or in the Visualize tab > expanded Lights panel > Lighting Units flyout, as shown here:
The Generic option uses default lighting without any lighting units. The International (lux) and American (foot candles) options enable photometric lighting.
Additional photometric lights that have a precise intensity, color, and falloff rate are included in the Photometric Lights tool palette, as shown here:
