草圖幾何疑難排解
The status of constraint is indicated by the color of the sketch entities, and you can use the Profile inspector tool to easily identify issues with your sketch constraints.

這個影片將說明疑難排解草圖幾何的方式。Onshape 使用顏色來表明草圖是不足限制、過多限制或完全限制的。過多限制草圖的圖元會是紅色的。不足限制草圖的圖元會是藍色的，完全限制草圖的圖元則會是黑色的。在這個範例中，分別有不足限制、過多限制或完全限制的草圖。
若要修正定義不足的草圖，可以直接加入尺寸，接著在上方邊線套用「水平」限制條件，最後在各邊套用「固定」限制條件。若要修正過多定義的草圖，請刪除「固定」限制條件，將兩側的直線設定為垂直，再將上方與底部的直線設為水平，然後可再加入新的「固定」限制條件。此時矩形即是完全定義的。
疑難排解是相當重要的。如上方範例所示，當您要使用像是「擠出」的特徵來將草圖做成零件時，可能會注意到某一零件被未正確地擠出，這樣會需要回到草圖中並使用疑難排解來發現草圖的定義是不足的。
Constraint status and colors
The color of sketch entities indicate its constrained status:
- Blue means under-constrained.
- Black means fully constrained.
- Red means a constraint problem (over-constrained).
The color of a constraint icon indicates its constrained status:
- Black on gray means well-defined.
- White on red indicates a problem.
- When selecting, non-fully constrained sketch points (blue and red) are prioritized over any overlapping, fully constrained sketch points (black).
Adding more dimensions or constraints will further constrain the sketch. Dragging entities may help you understand what constraints or dimensions you may want to add.

Using the Profile inspector
The sketch Profile inspector can help identify gaps in sketches, enabling you to close loops as needed. To open the Profile inspector:
- In the Sketch dialog, click the Show sketch diagnostic tools icon
. - Select Profile inspector from the menu.
- In the Profile inspector, click each issue to highlight it in the sketch. You can also use the Previous and Next buttons to cycle through issues. The issue will disappear from the Profile inspector dialog once it is resolved.
