how to draw a manhole in 3d

In this practice, you will define the geometry of the manhole by creating a unproblematic schematic of the construction profile. You will build this portion with dimensions that can exist modified from within Autodesk Civil 3D when the part is in use.

This exercise continues from Exercise 1: Defining the New Part in the Construction Itemize.

1. Click View tab Views console Front.

   The view of your Part Builder drawing expanse changes then that y'all see the Rim work plane from a front end view.

2. Aggrandize Modeling. Right-click Work Planes and and then click Add Work Aeroplane. The Create Work Aeroplane dialog box is displayed.
3. Click Offset. Proper name the work aeroplane Superlative of Riser ane and then click OK.
4. The command line asks you to Select reference piece of work plane. Click the xanthous bounding square of the Rim work plane.

   The control line asks you to Select Kickoff from work airplane. Plow on ORTHO. Select a location approximately 12" lower than the Rim work plane in the negative Z direction, and printing enter. In later on steps, you lot volition plant a more precise outset past equating these distances with structure parameters. A 2d piece of work plane is displayed approximately 12" below the first work airplane.

   

5. Repeat Steps ii through 4 to create the following additional work planes, using the following gauge offsets from the referenced work aeroplane:
   • Name: Top of Cone, Showtime: 12" below 'Top of Riser ane'
   • Name: Top of Riser 2, Offset: 24" beneath 'Top of Cone'
   • Name: Peak of Butt, Offset: 85" below 'Height of Riser 2'
   • Name: Bottom of Construction, Commencement: 200" below 'Top of Barrel'

   The new work planes are displayed. The new parameters are displayed under Model Parameters showing you lot the work plane offsets.

6. Change your view to be oriented above the Rim piece of work aeroplane. Expand Work Planes, right-click Rim and and then click Prepare View. The view is oriented to be above the Rim work plane.
7. Add together a circular profile to stand for the diameter of the frame. Correct-click the Rim work plane Add Profile Circular. At the command prompt, select a center signal for the contour at the judge heart of the piece of work plane and a radius of 12", similar to how yous would draw an AutoCAD circle. A circular profile is displayed, and an entry for a circular profile is displayed under the Rim work plane.
8. Aggrandize Work Planes, right-click Rim Add Geometry Point. Place a indicate at the approximate eye of your round contour. A point is displayed at the approximate eye of the round profile.

   

9. Constrain the profile so that the point will be forced to always be located at the middle of the profile. Right-click the Rim piece of work airplane Add together Constraints Concentric. The command line prompts y'all to select a first geometry and a 2d geometry. Select the betoken and the circular contour. The point moves to be at the middle of the circular contour, and a concentric constraint is displayed under the Rim work plane.
10. Add a diameter dimension that you tin after employ equally a structure parameter. Correct-click the Rim work aeroplane Add Dimension Bore. The command line prompts you to select circle or arc geometry. Select the circular profile on the screen. The command line prompts y'all to select a dimension position. Select a location on your screen that is close to the profile, but out of your way. A diameter dimension is displayed on screen as well as under your Model Parameters. The actual fatigued diameter and dimension value are unimportant at this fourth dimension.
11. Depict a circular profile on the Top of Riser 1 work airplane. Right-click the Acme of Riser 1 work airplane, and and so click Add Contour Circular. Post-obit the same process equally Step vii, draw a circular contour. You can use your heart OSNAP to ensure that the center of this contour matches the middle of the profile from the Rim work aeroplane. Set the radius to be only slightly larger than the Rim work aeroplane round profile to ease selection of this contour. The bodily radius is not important at this time. A circular contour is displayed.
12. Add a diameter dimension to the circular profile on the Top of Riser ane work plane. Right-click the Meridian of Riser 1 work plane, and then click Add Dimension Diameter. Follow the aforementioned procedure as footstep ten to place the dimension. A bore dimension is displayed for your second circular profile.
13. Repeat the previous two steps to create a round contour and corresponding dimension on the Top of Cone piece of work plane. You lot have three circular profiles with appropriate dimensions. Your dimensions may expect unlike than the post-obit analogy.
14. Repeat steps xi and 12 to create a circular profile and corresponding dimension for the Tiptop of Riser 2 piece of work airplane; however, this time, make the profile radius approximately twice every bit big (approximately 24" radius/48" bore). You should have four circular profiles displayed, and iv corresponding dimensions displayed in the modeling area, and under Model Parameters node.

    

15. Click View tab Views panel Front. Four profiles from front view are displayed.

    

16. Add a transition between the Rim circular profile and the Superlative of Riser one circular profile. This represents the manhole embrace and frame. Right-click Modifiers and and then click Add together Transition. The command line prompts y'all to Select Start Contour. On the screen, select the circular profile on the Rim work plane. The command line prompts you lot to Select Cease Profile. On the screen, select the circular profile on the Acme of Riser one work plane. A transition is displayed similar to the following illustration:

    

17. Right-click the transition on the screen, and then click Display Order Ship to Back. Add a transition betwixt the Top of Riser 1 circular profile and the Pinnacle of Cone round profile. This represents the manhole cover and frame. Right-click Modifiers and so click Add Transition. The command line prompts you lot to Select Start Profile. On the screen, select the round profile on the Top of Riser 1 piece of work plane. The command line prompts yous to Select End Profile. On the screen, select the circular profile on the Top of Cone piece of work plane.

    Repeat the process to create a transition between the round profiles on the Height of Cone piece of work plane and the Top of Riser two work plane. Remember that you may take to use Display Order Send to Back to transport the transitions to the back, then that you tin cull the profiles. To do this, right-click the transition on the screen, and so click Display Order Transport to Back. Transitions are displayed similar to the following illustration:

    

    These transitions stay dynamic to profiles used to create them, including adjustments to piece of work plane offsets, and bore dimensions.

18. Switch your view back to an overhead view past selecting the Elevation of Butt work plane, right-clicking and choosing Fix View. Your view switches to an overhead view in relation to this piece of work plane.
19. Make two circular profiles with corresponding dimensions on the Top of Barrel work aeroplane. Use steps 11 and 12 for reference. The first should be approximately the aforementioned size as the contour on the Top of Riser 2 work plane (24"R/48"D), the second should exist approximately twice every bit large (48"R/ 96"D). Two circular profiles are displayed on your screen. Ii corresponding dimensions are displayed both on screen and nether Model Parameters.
20. Make one circular profile with a corresponding dimension on the Bottom of Structure piece of work airplane. Utilize steps eleven and 12 for reference. The contour should be approximately the same size as the larger profile on the Top of Barrel work airplane (48"R/ 96"D). You should now take seven (7) total round profiles and corresponding dimensions both on screen and under Model Parameters. Recall that these diameters are gauge at this bespeak. The ones you lot created may not look exactly like the ones displayed in this tutorial.

    

21. Change your view to a Forepart view. The stack of work planes and the transitions created in step 17 are displayed.
22. Following the same methodology for the starting time batch of transitions created in steps 16 and 17, add transitions betwixt the Top of Riser 2 Profile, and the smaller Top of Barrel profile, so the larger Superlative of Butt contour and the Bottom of Construction profile. (You may have to utilize Describe Order to ship certain profiles to the back, in order to cull the correct one for each transition.) The model y'all created should now look similar to the post-obit illustration:

    

23. Alter your view to SW isometric.

    

24. Modify your visual style to Conceptual.

    

25. Change your visual fashion back to 2d wireframe, then alter your view back to Pinnacle view.
