As shown in Figure 2, be the functional block diagram of main frame 10 among Fig. 1.This main frame 10 comprises: receiver module 110, filtering module 120, computing module 130, comparison module 140 and reminding module 150.
Receiver module 110 is used for receiving the part that needs that the user selects from mould design figure file are checked.
Filtering module 120 is used for filtering out the predefined mould design figure file of user and does not need the figure layer checked, obtains view information, markup information and the attribute block information of all parts of above-mentioned selection in the residual graph layer.
Wherein, view information comprises the point, line, surface of each view of component part.In mould design figure file, in general, each part is to represent with three views of this part, for example front view, right view, vertical view.Wherein, front view is the projection of part on frontal plane of projection, just looks back resulting view from the part dead ahead.Right view is from the projection of the to the left resulting part of part front-right on edge-on projecting plane.Vertical view is the projection of resulting part on surface level that look down directly over part.When the design of a part was accurate, three views of this part satisfied following relation: the equal in length of front view and vertical view, and align i.e. " long aligning " mutually; Front view equates with the height of right view, and concordant mutually, i.e. " high concordant "; Vertical view equates with the width of right view, i.e. " wide equating ".
Markup information mainly comprises the length information (comprising numerical value and unit) that marks on each view of this part, as the length that marks on the height and width that mark on the length that marks on the front view and high, the right view, the vertical view and wide.When the design of a part was accurate, the length information that marks on each view of this part should be consistent with the physical size of each view.
In addition, each part has a corresponding attribute block, has write down the length information (comprising numerical value and unit) of this part in this attribute block.When the design of a part was accurate, the length information that writes down in this attribute of component piece should be consistent with the corresponding length information that marks on each view of this part.
In mould design figure file, also might exist some to be used to write down the part out of Memory, but not the attribute block of record part length information, filtering module 120 also is used to filter out the attribute block that these do not write down part length information.
Comparison module 140 is used for by the distance of each relatively more remaining attribute block and each part front view far and near attribute block and each part match that each is remaining.
Computing module 130 is used to calculate the length value of each view of each part that the user selects.
Comparison module 140, the length analog value of each view that also is used for calculating each part of gained compares, whether mate with each view of judging this part, whether whether judge promptly whether are front view and vertical view " long aligning ", front view and right view " height is concordant ", vertical view and right view " wide equating ".
Whether comparison module 140 also is used for when each views registered of this part, and the mark value of each view length of this part is compared with the length value of aforementioned calculation gained respectively, correct with the mark value of judging each view length.
In addition, comparison module 140 also is used for mark value when each view length of this part when correct, the length value that writes down in the attribute block with this part compares with the mark value of each view length respectively, whether correct with the length value that writes down in the attribute block of judging this part, whether length mark value is consistent on the precision that comprises the length value and each view.
Reminding module 150 is used for pointing out the reason modification for reference that makes mistakes when checking that discovery is wrong.For example: when comparison module 140 judges that each view of this part does not match, reminding module 150 promptings " front view and vertical view are long not to align ", or " front view is not concordant with the right view height ", or " vertical view and right view are wide unequal "; The mark value of judging certain view length when comparison module 140 is with the length value of calculating gained when inconsistent, reminding module 150 promptings " * view length/width/height is worth marking error "; When length mark value is inconsistent on the length value that writes down in the attribute block of comparison module 140 these parts of judgement and each view, reminding module 150 promptings " length/width in the attribute block/high value is wrong " or prompting " it is wrong that length/width in the attribute block/height is worth precision ".
