Description
Technical field
The present invention relates to Two-dimensional Engineering graphics fields, and in particular to size marking adaptively adjusts in a kind of two-dimensional engineering graphic
Method.
Background technique
In recent years, in mechanical design field, although threedimensional model design method obtains increasingly extensive application, Two-dimensional Engineering
Drawing is still the final output of enterprise product design and the important evidence of production and processing, and the surface that two-dimensional engineering graphic can express is thick
The markup informations such as rugosity, geometric tolerance, cooperation and dimensional tolerance be threedimensional model it is beyond expression of words and mark.
Currently, enterprise is when carrying out product design, often or using three-dimensional modeling and two dimension due to technical
Engineering drawing and the mode deposited.It how according to threedimensional model, obtains meeting the two of production requirement quickly as engineering drawing, becomes restriction enterprise
The key technology bottleneck of industry engineering drafting efficiency and designing quality.In response to this, classify to product seriation, if
It counts out a kind of parametric method and the Automation Design is carried out to homologous series product, can not only ensure standardization level, the standard of drawing
True rate, moreover it is possible to effective solution repeated labor, heavy workload, the problems such as time-consuming, low efficiency, realize homologous series products from
Dynamicization quickly goes out to scheme.
Realize that homologous series product parameters the Automation Design, content include: that threedimensional model parameterizes automatic modification, two dimension
Drawing automatically generates.On the basis of Drawing, the fast automatic generation method of two-dimensional engineering graphic, content includes: three-dimensional
The automatic modification of model, each view adaptively adjusts in engineering drawing, and engineering drawing size marking adaptively adjusts.
Size is according to the characteristic of three-dimensional figure feature modification in Solid works engineering drawing: the size of modified characteristics is marked,
Its numerical value changes automatically, and position coordinates are constant；The size marking influenced by deformation behaviour, position coordinates variation, numerical value are constant；
The size marking not influenced by changing features, then remain unchanged.
Currently, the problem of size marking encounters in figure when two-dimensional engineering graphic fast automatic generation is broadly divided into two kinds of situations:
(1) as shown in Figure 1 and Figure 2, from Fig. 1 to Fig. 2, FD430 clutch separation pull ring outer diameter increases to 150mm, Qi Tabao by 136mm
Hold it is constant, occur local feature size mark interfered with appearance profile line；(2) as shown in Figure 1, Figure 3, from Fig. 1 to Fig. 3,
Pull ring appearance profile size constancy is separated, pull ring notch increases to 35mm by 13.5mm, other are remained unchanged, and modification dimension line occur
The dimension line not influenced by changing features with other is interfered.It can be seen that in part outline modification, modification size is more than
Template size line length in reserve, the then size marking not influenced by changing features can interfere with the outer contour of part；In part
In local feature deformation, deformation size is more than template size line length in reserve, and deformation size marking also can be dry with other sizes line
It relates to.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and it is adaptive to provide size marking in a kind of two-dimensional engineering graphic
Method of adjustment is answered, this method solves the problems, such as existing size marking dislocation when two-dimensional engineering graphic automatically generates, to two dimension
The size marking position that interference is generated in engineering drawing is readjusted, and engineering drawing size marking is adaptive after realizing the automatic modification of product
Adjustment.
Realizing the technical solution of the object of the invention is:
Size marking self-adapting regulation method in a kind of two-dimensional engineering graphic, includes the following steps:
1) size marking for needing to adjust is determined；
2) size of adjustment size marking distance is determined；
3) the size marking position that needs adjust is adjusted.
In step 1), described determines the size marking for needing to adjust, and includes the following steps:
1-1) define arrays View(), view View(in engineering drawing is obtained with Get View function)；
1-2) defined variable Count obtains " display size in active view with Get Display Dimension Count ()
The number of object "；
1-3) by discriminant function, judges whether the value of Count is equal to and be adjusted sized objects number in view, determination will select
View；If the value of Count be adjusted in view that sized objects number is unequal, proving active view not is to be selected to regard
Figure, then judges next view, until the judgement of all views finishes；
The size marking for 1-4) traversing each view in engineering drawing, determines the size marking quantity of each view；
1-5) defined variable Number, using cyclical function Number=Number+1, judges Number if Number initial value is 1
Whether value is equal to the serial number for needing to adjust size marking, and determination needs to adjust size marking；It needs to adjust if Number value is equal to
The serial number of size marking then proves that current size is to be selected size, carries out in next step；It needs to adjust if Number value is not equal to
The serial number of size marking, then current size is not to be selected size, and judgement terminates, and carries out next size judgement.
In step 2, the size of the whole size marking distance of setting the tone really is that defined variable Number2 obtains modification ruler
Very little input adjusts size value, and defconstant Number3 is default size value, and the change function for bringing position coordinates into can be obtained and need
Adjust distance value.
In step 3), the size marking position adjusted to needs is adjusted, and is included the following steps:
3-1) with the Getposition function under Annotation, the position coordinates of current size are obtained；
3-2) by completing size positions to each size using Solid works secondary development function SetPosition2 function
The adjustment of coordinate.
Step 3-1) in, the position coordinates, the change function of length dimension labeling position coordinate are as follows:
SetPosition2(position(0)+(Number2-Number3)/1000, position(1)+(Number2-
Number3)/1000, position(2))；
The change function of diameter dimension labeling position coordinate are as follows: SetPosition2(position(0)+(Number2-
Number3)/2000, position(1)+(Number2-Number3)/2000, position(2))；
Wherein Number2: input adjustment size, Number3: default size, position(0): X-coordinate, position(1):
Y-coordinate, position(2): Z coordinate.
Size marking self-adapting regulation method in a kind of two-dimensional engineering graphic provided by the invention, this method effective solution
In the two-dimensional engineering graphic quickly generated after Variant Design the problem of size marking location conflicts, Two-dimensional Engineering can be effectively helped
Scheme fast automatic generation, instead of designer's manual setting size marking position, shortens the product design period, improve product
Design efficiency facilitates the standardization of drawing.The method has versatility, the two-dimensional engineering graphic parametrization based on Drawing
Quickly design can be used the method to the adjust automatically of size marking position in figure for automation.

Dim position As Object
Annotation=Di.Get Annotation // acquisition size coordinate position
Position=Annotation.Getposition()
Number = 1
Number ++
If Number=1 Then // selection serial number 1 size
Annotation.SetPosition2(position(0)+(Number2-Number3)/1000,
Position(1)+(Number2-Number3)/1000, position(2))
// 1 size positions coordinate of serial number is adjusted //
···
The size of the Then of ElseIf Number=7 selection serial number 7
Annotation.SetPosition2(position(0)+(Number2-Number3)/1000,
Position(1)+(Number2-Number3)/1000, position(2))
// 7 size positions coordinate of serial number is adjusted //
End If
