Negative Dimensions, and Setting Line Length On Placement

Two suggestions, or maybe this would be more one and a half I've gotten while messing around with OnShape would be the ability to set "negative" dimensions to flip the side a line or angle is going and the other one is the ability to set line length from the start, I've been using AutoCAD prior to this and swapped to OnShape due to the whole staying home situation and the one thing I miss was the ability to draw my lines out then add dimensions if needed. While I've started getting used to adding dimensions later and starting with the rough shape I feel that along with negative dimensions could speed up the work for many of us.

    Hi @mckeegan_curran - when drawing a line (for example) the length of the line is displayed. After placing the endpoint of the line, you can type in a length value which will then add a dimension automatically and size the line correctly. Once a dimension is created, you can edit it and enter a negative value to flip it to the other side. For a sketch to be considered "robust", in that it won't change unexpectedly, then it must be fully constrained (black) with either dimensions or constraints. Entering the length of a line without adding dimensions, therefore, will not be considered for implementation in Onshape at this time.
