Abstract
The invention discloses a method for performing frame selection of an entity by using a closed graph. The method is characterized by comprising the following steps of S1, selecting a closed polyline in a CAD drawing program; S2, extracting an object with a contour in the polyline; and S3, moving the object to a new layer. According to the method, the problem of reduced working efficiency of object selection is solved, and the problems of time waste, high error rate and high missing rate due to manual selection by users are avoided, so that the effect of improving the working efficiency is achieved.
Description
Technical field
The present invention relates to graph processing technique field, more particularly, to a kind of use closed figure carries out the side that frame selects entity
Method.
Background technology
With the continuous development of information technology, cad graphics system software has become as drawing personnel or designers not
The drafting instrument that can lack.Due to the lifting of scientific and technological level, the capacity expansion of storage device, designer is often in a cad
A lot of entities are drawn in drawing.So huge and intensive entity sets, is selecting single or part to cad system operators
A very big difficult problem is brought during entity.The intensive of entity is so that user chooses the probability of target entity to reduce.
Generally, the entity of cad figure can be processed by the control instruction in cad system, control instruction can
To include pruning entity orders, skew entity orders, entity chamfering order, mirror image entity orders and array entity orders etc..
At present in cad graphics process, it is more to run into object, very tired when wanting to pick out certain partial objects
Difficult.
Further, since during entity selection, user cannot foresee that control instruction is final to preselected entity
Treatment effect, therefore, after user can only be processed to the entity of selection by control instruction, just can know that the reality of selection
Whether body meets needs.If be unsatisfactory for, that proves that selection is wrong, and user must execute the order of rollback on cad, and entity is extensive
State to before command process re-starts selection again, causes to repeat to select often, so virtually to cause much not
Necessary work, leads to work efficiency drop.
Content of the invention
The technical problem to be solved in the present invention is: provides a kind of use closed figure to carry out the method that frame selects entity, energy
Enough select the entity of a closing, internal to internal for the entity or entity object being intersected with entity is picked out.
In order to solve the above problems, the invention provides a kind of use closed figure carries out the method that frame selects entity, it is special
Levy and be, the method comprising the steps of:
S1, choose the multi-section-line of closing in cad mapping program；
S2, extraction object within multi-section-line for the profile；
S3, described object is moved to new layer.
In this specific embodiment, described step 1, particularly as follows: when running into font, first Font processing is become multi-section-line, is led to
Cross modified line order and described Font processing is become multi-section-line.
In this specific embodiment, described object includes character layer.
In this specific embodiment, comprise the steps: in described s2
S21, in cad system, using feature function xyp_lib order provide interface obtain multi-section-line summit
Collection；
S22, the face override command wp utilizing in cad, carry out object choice according to vertex set；
S23, selection selection mode.
In this specific embodiment, run in described s2 multiple closings multi-section-line when, also include following method:
S21, the xyp-get-curvedivptlst function calling in cad, choose the peripheral vertex set of multi-section-line；
S22, the face override command wp utilizing in cad, carry out object choice according to vertex set；
S23, selection selection mode.
In this specific embodiment, in s21, described vertex set includes the coordinate on some summits.
In this specific embodiment, the method for described s2 also includes:
S21, in cad system, using ap order load evp.lsp order；
S22, operation evp order；
S23, selection selection mode.
In this specific embodiment, described selection mode, including inframe object is selected and inframe and with frame intersected object
Selected.
In this specific embodiment, in s3, new layer can be moved selected objects into by carriage return order.
The invention has the benefit that present invention reduces selecting the work efficiency problem of object, it is to avoid user passes through
Select by hand, the problem of time-consuming and fallibility leakiness, and then reached the effect improving work efficiency.
