CAD assembly drawings are indispensable drawings for the design of machines or components, and part drawings are the top priority. Whether the dimensioning is reasonable and whether the part drawing is in compliance with the requirements affects the processing quality of the whole part.
In the mechanical CAD software, Haochen CAD Machinery 2011 is a software with high usage rate. It meets the designer's requirements with comprehensive functionality, providing comprehensive and intelligent operational commands from the basic construction line to the final dimensioning. In the following, I will use the Haochen CAD Machinery 2011 downloaded from Haochen CAD official website to draw the “Part 3â€. Through this process, I will briefly demonstrate the drawing method.
1. Click [Haochen Machinery] - [Drawing Tool] - [Series Circle (MC)], quickly draw concentric circles with diameters of [12] and [21], and use the centerline command to quickly draw the circle. Center line.
2. Use the multi-line command [PL] to draw the line [48°] and the long line [18] of the line L1 from the intersection of the center line, and use this end point as the starting point to draw a line with an angle of [18] long [39]. [L2].
3. Using the [Offset] command, the offset lines L1 and L2 are shifted upwards and downwards [7.5], respectively (see Figure 1).

4. Quickly use the offset, arc, trim, command to draw the remaining graphics (Figure 2).

Basically there are two types of Diameter Tape Measure, one is Pipe OD Tape Measure Diameter Circumference, another is ID (Inner Diameter) PP Tape Measure
Pipe OD Tape Measure Diameter Circumference
Product Description:
The 2-meter Pipe OD Tape Measure Diameter Circumference is made of reliable material to satisfy precise diameter measuring requirement.The reading for the perimeter, accurate to 1 mm. The tape is double sided with circumference (measures in cm & inch) and diameter (measures in inch & inch) on the either part. Pipe od tape measure adopts fiberglass tape to deliver water and stain proof effect and to ensure that it is of good elasticity for diameter measuring. The retracting mechanism is built in the durable ABS case, thus service life is extended. Wintape provides the diameter tape measure with other patterns and offers customized logo for you.
ID (Inner Diameter) PP Tape Measure
Product Description:
Inner diameter tape measure is made of PP material that is of excellent stress tensile strength and high elasticity. The scale numbers are already been calculated so the tape gives you the result directly without calculating. The practical ID measuring tape can be adopted in various ways such as pipe and container measuring. The double sided inner diameter measuring tape makes number reading easier and more convenient.
