Measure Distance button disabled when viewing a Linked Object Post by bgoodr Mon 12:43 am Use-case: I need to measure the distance between two vertices between two vertices on the same, or different, arbitrarily linked-from objects within the linked-to objects 3D view. The first activates a task dialog with advanced options to choose which types of measurements to make, to choose to save those measurements as objects in the document and optionally with selection filters. from centerpoint for circles and ellipses and maybe from center of mass of arbitrary faces and middle point of arbitrary edgesĪs for interface I would like to have at least two measurement commands: "Measure" and "Quick measure".Part/compound, same as shell/solid but differentiated per shape type.mass (for solids with assigned density).Would be a good idea to describe desired interface, measurement modes and such. Experience in using CAD software is beneficial.Familiarity with any or all of the following will be helpful.Understand of FreeCAD API is obviously beneficial.Programming languages are C++ and Python.This work will provide an introduction to the FreeCAD code base and the use of supporting software such as OpenCascade and Qt. Work must be repeated, for example in creating a Dimension in a drawing when the corresponding measurement already exists in the 3D model.New users find the diversity of measuring tools confusing.Individual workbenches have created measurement tools that filled the needs of that workbench only.A single method of measuring objects would smooth workflow and reduce learning time. There are currently several ways of measuring objects in FreeCAD: Draft Dimensions, TechDraw Dimensions, Manipulator Caliper, Measure Distance, Measure Linear, etc. The solution which will be picked is based on the implementation of the algorithm, but usually, it does a rounding to the closest value.This page is describes a potential Google Summer of Code project regarding upgrades to FreeCAD's measurement functions. If you notice with respect to the center of the circle you could say that the first solution you are presenting is for the negative solution ( $x=-5$), while the second solution is $x=+5$. For that equation there are two solutions $x_1 = -5$, and $x_2 =5$, which are both equally valid. ![]() The reason why you have the problem is that at some point you have an equation of the form $x^2 = 25$. $(x_0, y_0)$ the coordinates of the center.So in this particular scenario, one of the points that define the vertical blue line is part of the circle, therefore it needs to satisfy an equation of the following form: So they try to convert them in mathematical formulas. One thing to remember, is that parametric modelers try to solve the constraints. UPDATE: to explain why its fully constrained However, you might be able to use a function in the dimension (e.g. The problem in this case is that the angle in most cases will not be a round number. One way would be to give the angle with the horizontal, instead of providing the 5mm length. ![]()
