CAD Clinic Civil 3. D Editing Alignments with Civil 3. D7 Nov, 2. 00. 6By Mike Choquette. Use the editing toolbar to dynamically adjust and refine your alignment. In Mays CAD Clinic I covered the basics of what a Civil 3. D alignment object is, as well as how to import and convert polylines into alignments in Civil 3. D 2. 00. 7. In Julys column I described the usefulness of fixed and floating alignment constraints when laying out an alignment with known line and curve data. The September column examined the free alignment constraint and how to use it in a design. This article completes our review of Civil 3. D horizontal alignments by considering techniques to dynamically adjust them once they have been created. Auto. CAD Modify Commands. The simplest way to adjust a Civil 3. A compilation of AutoCAD tips. Read all 100 of them to increase your productivity Autodesk supports the student community by providing students, educators and institutions free access to 3D design software, learning tools, programs and competitions. D alignment is to change it with standard Auto. CAD commands like Move, Rotate, Stretch and Grip Edits. A note to former users of Land Desktop yes, this actually works and works well. Civil 3. D automatically updates an alignment definition as soon as you complete one of these commands. The Auto. CAD Undo and Redo commands are also a valid choice if you change your mind, so go ahead and explore all those alternatives If you are new to Civil 3. D and Auto. CAD in general, we recommend that you also review other CAD Clinic articles about Auto. CADs Modify commands.

Civil 3. D alignments have grips available at the PIs points of intersection, as well as the center point and endpoint of lines and curves though some curves have unique grip configurations based on the constraints chosen at creation. If a free circular curve was assigned a certain radius, moving its PI through a click and drag would cause the curve and its adjacent tangents to be re drawn while holding the same radius value. The grip at the center of a free circular curve can be relocated as a pass through point, which causes the curve radius and accompanying line segment lengths to change in order for them all to remain tangent. Gripping and moving the center point of a line segment lets you relocate that line while maintaining the same bearing, which causes adjacent curves to update accordingly.

If you havent experimented with profiles and corridors yet, keep in mind that changing the alignment can automatically update the existing ground profiles and cross section linework. This flexibility is an excellent example of the dynamic design environment provided by Civil 3. D. Graphical Edits with the Alignments Toolbar. Beyond the core Auto.

D also allows users to graphically edit an alignment through features in the Alignments Layout Tools toolbar. This toolbar appears when you launch the Alignments Edit Alignment Geometry from the pull down menus, or if you select an alignment object, right click and choose Edit Alignment Geometry. Note that this toolbar is only visible during alignment creation and editing it disappears from your screen when not in use. While working with this toolbar you may want to stop yourself from using the Escape key since it will end your alignment editing session and cause the toolbar to disappear. Although this disappearing act conserves screen real estate, it can be a little disconcerting. Instead, when you want to abandon an edit, use the Undo button in the toolbar. If youre like me, that may take some getting used to So, if the toolbar ever evaporates on you before youre done editing, bring it right back in with Alignments Edit Alignment Geometry. On this toolbar, the graphical edit commands include Insert PI, Delete PI and Break Apart PI circled above. Creating a new PI inserts an angle point at the selected location, which can later have a curve fit through it with one of the Create Curve Commands covered in the July and September articles. Deleting a PI does just that it deletes a point of intersection and any curves that pass through it. Blue Note Trip 9 Rar more. This approach re draws an alignment from the first tangents start point through to the following PI if free curves are present illustrated below. Adding or deleting a PI is a significant alignment change that may only be necessary when abandoning one alternative for another, very different layout. The Break Apart PI command removes the single PI grip and replaces it with two line segment endpoint grips. The advantage to having a broken apart PI is that you can select one of these grips and adjust it independently of the other, which allows you to change one tangents bearing or length without adjusting the bearing of the other. If you would like to delete a curve or line segment, use the Delete Sub Entity command. It is sometimes necessary to delete an entity and replace it with another in order to apply different constraints such as to replace a free curve with a set radius with a free curve through a designated pass through point instead. Deleting a free curve causes the alignment to be re drawn through the PI as an angle point. Deleting other kinds of curves or line segments can cause a gap to form in the alignment that is not automatically reconnected. You can bridge this kind of gap by adding more lines and curves, or by dragging line endpoint grips together to form new PIs. Tabular Edits with the Alignments Toolbar. There are also a handful of commands that allow you to adjust alignment features in one of two tabular views. The Sub entity Editor is a modeless dialog box titled Alignment Layout Parameters that lists design properties of an alignment line or curve. Those features that can be edited numerically appear in bold, such as the curve radius shown below. To activate the editor click on the Pick Sub entity button and choose an entity to review. To dismiss the editor, click on the Sub entity Editor button on the toolbar or click the red X in the upper right of the dialog box. The Alignment Grid View command calls up the Alignment Entities Vista in the Panorama window, where you can review each alignment entity as a row in a table. As with the Sub entity Editor, design features that can be edited numerically appear in bold. As a final note, remember that there are Undo and Redo command buttons located in the far right of the toolbar. These let you revisit previous changes while still in the Edit Alignments command. Keep in mind that the core Auto. CAD Undo command Edit Undo undoes all edits completed during your previous edit alignment command, not just the last individual change you made. Therefore its preferable to use Undo and Redo from the toolbar whenever possible, since they only reverse the last incremental change made during an alignment editing session, not the entire session. Summary. As the last portion of our review of Civil 3. D alignments, this article overviews the tools available to adjust and refine horizontal alignments. These dynamic tools offer unprecedented advances over similar editing steps provided by Land Desktop and other traditional civil engineering packages.
