Autocad examples 2d

And be sure to check out my Tuesday Tips article with an overview of 2D constraints. The specific example I will cover here is for constructing utilities under a major road or highway where we cannot dig a trench due to the high volume of traffic on the road.

Instead, we will propose borehole construction which will dig a hole underneath the road using a casing pipe that will carry the utility pipe.

The diagram below shows the design standards that we must follow for this project. So, looking at the diagram, we can see that the standards call for a range of deflection angles for the entrance and exit of the pipe. Note though that the entrance and exit can be swapped based upon the existing conditions on either side of the road. But, in the real world, the existing ground will vary, the depth to the pipe will need to be adjusted, and the deflection angle will need to follow this adjustment.

Below is our area of design. I have a profile view cut with Civil 3D at a scale of so that we can design this without having to worry about an exaggerated scale. To finalize the geometric constraints, I will add a vertical constraint to one of the vertical lines as there is already a parallel constraint associated to the two lines.

Now, we will need to add the geometric constraints to add the appropriate angle of deflection on either side.

Close Search for. You can make a change in your applied 2d Command according to you. You can change the pattern of 2d Command from this list also. Step If you want to apply 2d Command of a specific color, then choose the color from this list and click on the Preview button of this box.

Step The color of your 2d Command will be changed in red like I set the red color. Step You can also fill color inside blocks of 2d Command by choosing a color from this list. Step For example, I choose a yellow color, then click the preview button, then it will look like this.

Step Now, you can increase or decrease the scale of your 2d Command according to your requirement. For changing it, just click on the box of scale and enter your value. Step And click on the preview button, and your 2d Command will change like this because I scale down it as per my requirement. Step Next, you can also change the angle of the selected 2d Command by changing the value of the angle in the box of the Angle option of this box.

For example, I take 45 degrees as a 2d Command angle and click on the preview tab; then, my 2d Command will be inclined at 45 degrees like this. Step You can also change patterns by seeing the preview of the pattern just by moving the mouse cursor on the pattern, and the pattern will change automatically in your selected block as a preview. Step If you want to remove this 2d Command, then click on the Remove option of the 2d Command creation tab.

Step Then it will ask you to select the boundary of 2d Commanded object, and once you select it, the 2d Command will be removed from your object. Step You can change the color of your selected 2d Command from this option also.

Step You can increase or decrease the visibility of your 2d Command by increasing or decreasing the value of the 2d Command Transparency option. Step You can choose the origin point of 2d Command from this option. Just click on it. Step And choose the origin point on your object. For example, I choose this endpoint as the origin point of my 2d Command.
