De funktioner i Tegn-menuen. |
 |
Funktionerne tilgængelige i dit program afhænger af din programkonfiguration og kan afvige fra denne beskrivelse. Aktuelle oplysninger om betjening af funktionerne kan altid fås ved hjælp af programhjælpen. |
Hver indtastning (sektion, kontur, ..) begynder med en positionsudveksling. En tilbagetrukket position er en fri bevægelse af maskinen med hævet værktøj til startpositionen. 2D-fræsbevægelser udføres f.eks. ved hjælp af position indsnit. En indsnit position er en fræsning af maskinen med sænket værktøj eller indskåret til den specificerede position. Den ønskede fræsedybde for PosnE bestemmes f.eks. ved hjælp af den indskårne dybde af lagerværktøjet eller i henhold til beregningen af fræsedataene i CAM-området.
| Position A (PosnA) (Position tilbagetrukket = fri bevægelse til startposition) |
Indtastningsstartpunkt for grafikken. Med Position A bestemmes starten på en kontur eller en sektion.
Ingienørhjælp kan aktiveres ved hjælp af midterste museknap (alternativt ved hjælp af eller og højre museknap ).
| Position E (PosnE) (Position indsnit = maskinfræsning) |
Indtastningsstøttepunkt af en 2D-polygon absolut i X og Y. Under cursoren input, føres også en linje kontinuerligt som “gummibånd”. Kun PosnA kan indtastes med et tomt lag.
Handlinger:
| ,,: | Position indsnit. |
| ,: | Ingeniørhjælp (se ovenfor). |
| ,: | Abort indtastning. |
| <W>: | Position tilbagetrukket. |
| <C>: | Luk kontur |
Ingienørhjælp kan aktiveres ved hjælp af midterste museknap (alternativt ved hjælp af eller og højre museknap ).
| Position 3D (Posn3D) |
Indtast en absolut position 3D med X, Y, Z-koordinater. Efter cursor input kan koordinaterne redigeres i 3D. Hvis kun 2 koordinater eller Z = 0 indtastes, oprettes der derefter en 2D-position (PosnE). En 3D-position kan ændres ved hjælp af rediger . forskyd position.
Ingienørhjælp kan aktiveres ved hjælp af midterste museknap (alternativt ved hjælp af eller og højre museknap ).
| Punkt (boring) |
Funktionen Punkt placerer en tilbagetrukket position (PosnA) efterfulgt af en indsnit position (PosnE) ved punktinput. Dette punkt, ligesom næsten alle tegnfunktioner, kan indtastes enten ved hjælp af cursoren eller alternativt dets X/Y-koordinater via tastaturet. Efter input markeres punkter med punktsymbolet . Borets dybde bestemmes ved hjælp af den indsnittede dybde af lagerværktøjet.
Bemærk: For indtastning af et punktraster kan man arbejde med fangstgridstøtte. Ved hjælp af operat . serietile kan der oprettes regelmæssige punktjusteringer ved kopiering. Punkter kan forsynes med (boring/fræsning) egenskaber i HCAM.
Ingienørhjælp kan aktiveres ved hjælp af midterste museknap (alternativt ved hjælp af eller og højre museknap ).
| Stræk |
 |
Indtastningspunkt (vektor) for en indsnit eller tilbagetrukket linje. Ved indtastning via tastaturet indtastes adskillelsen i X- og Y-retning mellem den sidste position og målpositionen. Cursoren input adskiller sig ikke fra indtastning af en position.
Ingienørhjælp kan aktiveres ved hjælp af midterste museknap (alternativt ved hjælp af eller og højre museknap ). |

| Free-hand line |
Draw a free-hand line using the cursor. After pressing the key the cursor positions are taken over continuously until release and displayed as frequency polygon (section). Free-hand lines are optimised automatically by the program.
| Spline |
Input a spline using any desired number of support points. the spline resolution (number of the interpolation points) are determined through Input parameters . Spline resolution.
Using the function Spline the next constant curve is drawn through a number of support points. The calculated curve in all cases runs through these points. With small changes in slope these can lie far apart, in tight areas of the curve they should, however, be selected more densely. Points of discontinuity, i.e. kinks in the curve, cannot be input as spline. Here the function must be discontinued and a new spline started. The last position input determines the slope of the curve in the end point.
During the input a line to the position is also carried as “rubber band”. As soon a 3 support positions are input the start of the curve is also drawn. A support point is adopted using . Using the function is ended (last spline position). If, during the input of a spline, a start point is selected near the contour start point, then this point is captured and the contour closed. Further point input creates a new spline with new contour start point.

During the input of the 2nd position a line is carried continuously as “rubber band”. The circle is codrawn with the input of the 3rd position. |
