| Summary | 0000888: Add more measurement capablity to the length/distance constraint | ||||
| Description | At the moment the Length tool works in the following manner: Select 1 line - a dim is created in parallel with line Select 1 line and a point - a dim is created perpendicular to line Select any 2 points - a dim is created parallel to 2 points New additional capability: Select any 2 Lines: If the 2 lines are parallel - a dim is created perpendicular to line If the 2 lines are not parallel - a dim is created same as the angle feature Note: dim is short for dimension line. | ||||

> If the 2 lines are parallel - a dim is created perpendicular to line > If the 2 lines are not parallel - a dim is created same as the angle feature Both can be done by choosing a point of the 1st line and a 2nd line. Btw, trying to set a dim directly to two lines could be problematic: * parallel: what happens if you remove the parallelism after setting the dim? * non-parallel: how do you define the distance between two non-parallel lines? |

Let me start by saying that the FC dimensioning works as it is intended and it works great. I am not criticizing it in any way. It is getting the job done! Here is the background for this feature request: 1. Even though the dimensioning works the way it was intended, it took me a while to get used to it. 2. I thought adding these 2 features would make FC an easier transition for folks coming from Solidworks,Siemens NX,Inventor, & PRO-E. In these programs you just select objects (line to line, line to circle, circle to circle, line to arc, etc) not the vertex points. It's very intuitive and think that the FC users would love it. Clarifications: * Non-parallel, the dimension should be an angle, not a distance. * Parallel, if the lines are no longer parallel, either remove the dimension or convert it to an angle such as the non-parallel case. |

Maybe I just missed the point but IMO this would be a confusing behaviour. Nevertheless, I assign it to the programmer who wrote most of the sketcher code and then it's up to him to decide if it's useful or not. |

I am not sure what a dimension is here in the Sketcher context. Is it a constraint? Starting in v0.16 there are reference constraints (reference dimension) that may be in the direction of what you indicate. |

Hi everyone This is a very old ticket, I am trying to clean up mantis a bit. I think this is not a good idea for the reasons Werner stated. But also doing something that does not fit well with the FreeCAD work flow just because some other program works that way, is not in itself a good reason to do something, in my opinion. I was going to ask for opinions first but I think its more efficient to just close this, we can reopen it if you disagree. |
