As you can imagine, given the vast capabilities of
AutoCAD, there are a lot of
commands available.
Drawing.
| SHORTCUT/ COMMAND | DESCRIPTION |
|---|
| L/ LINE | Create a simple line |
| MI/ MIRROR | Produce a mirror copy of an object |
| MLINE | Create multiple parallel lines |
| PL/ PLINE | Make a polyline |
To create a hollow solid:
- Click Solid tab > Feature panel > Hollow to display the Hollow Solid dialog:
- Use the dialog to remove a face of a solid and offset it to create a hollow solid.
- Move the cursor over a solid.
- Click the face of the solid you want to remove to highlight it.
Create tube and pipe runs
- With an assembly file open, click Environments tab Begin panel Tube and Pipe .
- In the Model browser or graphics window, right-click the blank area and select Create Pipe Run.
- Do either of the following:
- Click OK to close the dialog box.
In the following steps, you will create an Autodesk Civil 3D pipe network from the polyline. Click Home tab Create Design panel Pipe Network drop-down Create Pipe Network From Object Find.
To Draw a Plumbing Run
- If necessary, activate the Plumbing workspace.
- On the Plumbing Line tab of the Plumbing tool palette, select a plumbing line tool.
- On the Design tab of the Properties palette, under General, specify a plumbing line style.
- Specify a system.
- Specify an elevation.
Select the profile view. Click Profile tab Launch Pad panel Draw Parts In Profile View Find. In the drawing, select the pipe network parts you wish to add to the profile view, or enter E to select an entire pipe network. Select a profile view.
To Create Pipe Networks From Objects
- Click Home tab Create Design panel Pipe Network drop-down Create Pipe Network From Object Find.
- In the drawing, select the object.
- In the Create Pipe Network From Object dialog box, specify a name for the pipe network.
- In the Description field, enter an optional description for the pipe network.
After you acquire an object snap point, use direct distance to specify points at precise distances along alignment paths from the acquired object snap point. To specify a point prompt, select an object snap, move the cursor to display an alignment path, then enter a distance at the prompt.
ARRAYEDIT (Command)
- Select array. Selects an array for editing.
- Source. Activates an editing state in which you can update the associative array by editing one of its items.
- Replace.
- Base point.
- Rows.
- Columns (rectangular arrays)
- Levels.
- Method (path arrays)
A curve which can be turned continuously inside an equilateral triangle. There are an infinite number of delta curves, but the simplest are the circle and lens-shaped -biangle. All the curves of height have the same perimeter .
To dimension a radius, first select the circle and then specify the position of the dimension line (and the dimension value). The dimension value can be written in any angle on the circle. Regardless of the end point position, the dimension value is always the radius. Insert > Dimensioning > Radius dimension.
A radius of a circle is the length of a line from the center of a circle to its perimeter. When measuring a curved bend you can measure from the inside of the bend or outside to yield the inside or outside radius respectively. From that, you can deduce your true center-line radius.
You can determine the degree of any curve by first finding the circumference of a circle. Multiply the radius of any circle by π, a numerical constant that begins with 3.142, and represents the relationship between a circle's diameter to its circumference. Multiply that product by 2.
Help
- Click Analyze tab Inquiry panel Continuous Distance. Find.
- Select Base or Continuous.
- Select two points to display the distance between the points.
- Select another point.
- When you finish selecting points, press Enter to view the total of the distances.
A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.
Help
- Click Annotate tab Dimensions panel Dimension. Find.
- Hover over an arc or an arc segment in a polyline.
- At the prompt, enter L (Arc Length).
- Select the arc or the arc segment in a polyline.
- Click to place the dimension line.
- Repeat steps to continue dimensioning or press Enter to end dimensioning.
