27-3. Example3 Tutorial Finished Sec Drawings

For this Example 3, I volition travail exhibit how a 2D drawing inwards which I volition utilization the LINE, CIRCLE as well as TRIM commands.

Finished drawing looks like.

So let's start alongside the next settings. I accept defined the Yelow color Line that Layer.

STEP 1

First, nosotros volition depict a horizontal symmetry as well as at its middle at Midpoint, nosotros volition depict a vertical minute symmetry.
At the center, nosotros volition depict the circle using the CIRCLE command as well as ready the diameter 30, or the radius 15.



Command:
Command: _circle
Specify middle betoken for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter]: xv [radius circle no. 3]

Also, because the 2 extreme circles are located symmetrically of the large circle, at the same distance of xxx units depict from the middle of the large circle 2 auxiliary lines (which nosotros volition later on remove) the values xxx as well as hence at their ends the circle alongside the radius 8.

Command: _circle
Specify middle betoken for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <7.5000>: 8 [radius circle no. i as well as 2]

Now, nosotros accept this drawing similar icon below.

Now nosotros bespeak to depict the outer parts of the line. From the middle of a circle is drawn volition move higher elevations of the circle alongside the kickoff drawing. OSNAP push clitoris vogue is turned 'On'.

STEP 2

The kickoff terminate of the circle 4 as well as 5, R = xv as well as hence srednju6, R = 25

Command: _circle
Specify middle betoken for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <8.0000>: xv [radius circle no. 4]

Command:
Command: _circle
Specify middle betoken for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <15.0000>: xv [radius circle no. 5]

Command:
Command: _circle
Specify middle betoken for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <15.0000>: 25 [radius circle no. 6]

STEP 3

Now using OSNAP mode (TANGENT choice is 'On') volition connect at a tangent circles exterior of the drawings. Carefully written report the figure below, plough 'Off' the other connecting betoken OSNAP,  that yous produce non confuse.

STEP 4

You bespeak to click on the LINE ascendancy push clitoris as well as hence target the outer circle of 4/6, 5/6 as well as when the magnetic betoken appears to Tangent, click a Mouse.

STEP 5

Previous activeness to brand all iv external connecting lines. After that, yous bespeak to accept this drawing.

STEP 6

So instantly nosotros bespeak to cutting off (remove) the excess line, as well as nosotros volition utilization the TRIM command.
Select the external lines alongside which yous are connecting the circles. They volition move transformed into a dashed line. All the adjacent footstep every bit yous overstep away on to cutting off, volition take away the contact betwixt the terminate points of selected lines.

STEP 7

Click the correct mouse push clitoris or press Enter to consummate the selection. Now click through the internal parts of a circle that is utilization of the circle that nosotros bespeak to move cutting or trimmed.

Finally, nosotros accept a drawing every bit the kickoff icon of this Blog. Delete helper scarlet lines.
NOTE, This drawing could move drawn inwards a unlike way. Example, depict one-half of the drawing as well as hence mirror it over the symmetry alongside the MIRROR command. (Either vertically or horizontally).
