Pro/E curved surface designs experience 1, the distinction of Curve and Tangetchain. Do two for instance successive quadrilateral curved surface, curved surface A cited Curve1, when founding curved surface B, had better cite the Tangentchain of A is not his primitive Curve. Because although the edge of the A on the principle (Tangentchain) namely Curve1, but after generating curved surface, its edge had had the deviation on precision with primitive Curve. What what thought to assure curved surface is successional, answer to choose Tangentchain as far as possible. Compensatory: When defining attrib border condition, tangentchain need not choose curved surface (because be originally on curved surface) , and Curve needs to choose tangent curved surface, pass the curved surface that this Curve founds before namely. (Direction of axes of PivotDir(of the 2) , option when becoming sectional to scan) understand. Regard primitive trochoid as above all the combination of countless origin, what be in in either origin is sectional consult for: The tangent that origin, origin is in, and cross origin and as perpendicular as Datum face linear (can understand it to found Point-on-plane axis) . A very good example is the mouse face tutorial of Ice, regard the Datum that becomes sectional to scan as in order to separate modular side the face, because this can assure either,scanning orders the part of drawing of patterns of place. (3) , found successive mixture curved surface, its Curve wants successive definition, in order to make sure curvature is successive; And curved surface can be generated apart first, establish the join range among again. (4) , when founding a curve through the dot, can undertake fine tuning with Tweak, recommend choice datum plane to undertake planar adjustment, choose another again next fiducial undertake modulatory, such reference point won't run in disorder. (5) , if demand of curved surface quality is higher, use as far as possible quadrilateral curved surface. (6) , scanning curved surface arranges advanced face as far as possible, because it cannot define attrib border join. (7) , when occurrence ＞ when 4 edges, can extend attrib border line sometimes and intersect, form thereby quadrilateral curved surface, undertake cutting handling again next. (8) , those who become sectional to scan is perpendicular at primitive contrail: Contrail of vector of X of primitive contrail ＋ is local coordinate fastens origin: Primitive contrail can inspect countless gather of the dot, these are nodded even if local coordinate fastens origin; Z axis: The tangent way that primitive contrail handles in origin; X axis: Primitive contrail forms as perpendicular as Z axis plane in either point point, this plane and X vector contrail form point of intersection, origin points to point of intersection to form X axis namely; Y axis: Decide by axis of origin, Z, X axis. (9) , perpendicular the curved surface law at orbit to NormtoSurf: Local coordinate fastens origin: Primitive contrail can inspect countless gather of the dot, these are nodded even if local coordinate fastens origin; Z axis: Tangent contrail can inspect countless gather of the dot, every tangent of the dot is Z axis; X axis: By Z the axis can fix the plane that XY axis is in, the curved surface that crosses primitive contrail with another intersects, get X shaft namely; Y axis: Decide by axis of origin, Z, X axis. (10) , perpendicular the use law at orbit to orbit UseNormTraj: Local coordinate fastens origin: Primitive contrail can inspect countless gather of the dot, these are nodded even if local coordinate fastens origin; Z axis: Tangent contrail can inspect countless gather of the dot, every tangent of the dot is Z axis; X axis: Origin points to a law to orbit, it is X axis namely; Y axis: Decide by axis of origin, Z, X axis. (11) , tangent contrail: Use at defining sectional tie. 2, general flow: Dot, line, face, just be hypostatic next! When tectonic Surface, curve must successive; When if be in,doing Surface, cannot when set Normal, Tangent, it is commonly in front Curve was not done good, but first Free, after modification Curve, again Redefine! 3, OK also such: ? Kui of anxiety of tip of Chun Xi of tuft of  talk in one's sleep newly-risens sun? of  that  arrives next among modelling go doing curved surface.

This is the move that I make curved surface commonly.

4, I am perpendicular to the understanding of axes direction at (primitive contrail chooses plane to go up in place) of umbriferous contrail sectional maintain appearance and tie. Myself feeling is right Curver and T-chain. I feel bemused, but Tallrain place tells let me understand a few doubt previously 5, it is OK that I think, should be in only the definition is tangent it is to be able to give Gao Liang (orchid color) the tangent curved surface that correspondence chooses by the side of, can define tangent, compound of course the error with the curve after and little presence of original attrib border meeting, serious view uses original attrib border BOUNDARY, but can cause PATCH increase so; If want,accomplish G2 or should the curve, attrib border and compound! And PATCH is opposite a bit lesser have future job profit.

After all curved surface just designs the job begin! Can the amount that through adjusting reference point reduces Patch. Can the amount that through adjusting reference point reduces Patch. 6, not all curved surface is OK, and compound the face that crosses a curve to make is a whole, control very easily! 7, I will do a summary: (1):BWhen ONDARY if be whole border, need not integrated curve, use border directly, if be broken border too, use certainly compound (approximate) attrib border (G1 above ability is OK and only compound) , advantage is to be able to define G1, g2; can control this curved surface very well, attach most importance to especially to follow-up measure should.

Although can be put in so called error, but can accept completely to general electric equipment product! ! (2):ILOT is very the command of VONDERFUL, everybody must understand adequately, use extensively, be in especially when the basis separates modular side in ID shop front and Mo Ju, he can assure those who divide modular face both sides to dial feel part, use first become sectional scanning does referenced curved surface (certain choose feels PILOT way planar) of direction, spreading noumenon curved surface next, this is to be about the referenced range that makes before reference, (G1 or G2 see you.

8, scanning curved surface arranges advanced face as far as possible, because it cannot define attrib border join. 9, about advanced the direction that sweeps the X that sweep past, Y, Z decides an issue I and you have different opinion: NORMTOORIGINTRAJ:Z: ?  backbone Liu Le of 5 that Xing relatively Zuo : ?

Everybody says 10.

Still have a bit: Just discover in last few days, the curved surface that Style does is being done as Surface on quality. The curved surface that can do with Surface should do me to feel be when Bound less with Style, after had better combining broken border approximately again state face, although the likelihood after state face cannot create entity, can be the same as curved surface curved surface face of outspread have a youthful look is hypostatic, do I say not to know everybody to you can understand so? The attrib border line that uses complex face occasionally does blending, can do Cure with attrib border line first (have two end points only) the range that such making is controlled easily.
