Cut and carve characters design, and design process is recorded among data file in real time;
9th step, the type face steelframe physical model that the 8th step is completed is assembled, and interference checking is carried out in assembly environment, will
Inspection result is exported into excel forms;And crucial point coordinates can be installed in assembly environment measurement;
Tenth step, according to the 9th step interference checking result, in assembly environment, passes through to the type face steelframe that there is interference situation
The mode of line cutting carries out grooving design, solves interference problem, and modification result is preserved to part;
11st step, according to the modification result in the tenth step, output element Two-dimensional Engineering map file, work is completed.
5. the design method of metal plate sculpture type face steelframe intelligent design system according to claim 4, it is characterized in that, the 6th
In step, the end face method for repairing and mending, including four steps;
Sought according to the indicatrix extreme coordinates data of type face steelframe physical model in bias curve end-point data xml document
Look for corresponding bias curve extreme coordinates data;
According to the end-point data recorded in xml document and indicatrix end points and bias curve end in the steelframe physical model of type face
The triangle pair type face steelframe entity that point is constituted carries out excision operation, obtains two kinds of operating results:TRUE and FALSE;
ToExcision result is TRUE result in step, by the end-point data recorded in xml document and type face steelframe entity mould
The triangle that indicatrix end points and bias curve end points are constituted in type is extended continuation and type face steelframe physical model is carried out
Excision;
ForExcision result is FALSE result in step, according to the end-point data recorded in xml document and type face steelframe
The triangle pair type face steelframe entity that indicatrix end points and bias curve end points are constituted in physical model carries out stretching repairing behaviour
Make.
6. the design method of metal plate sculpture type face steelframe intelligent design system according to claim 4, it is characterised in that the
In eight steps, made a mistake and when causing design process to be interrupted when due to physical model mistake or computer software and hardware, data text
The last entity steelframe numbering for completing operation is record in part, when re-starting the design of the 8th step, design system can be with
Record in data file proceeds type face steelframe grooving from interruption position, split and design of carving characters.
