![]() ![]() From FreeCAD's strong mechanical background, we learned the importance of always working with solid objects. Architectural objects are always solids.Here are, for example, a couple of interesting features of FreeCAD's Arch Workbench that you'll hardly find in other BIM apps: As it is still under development, don't expect to find here the same tools and level of completion as grown-up commercial alternatives such as Revit or ArchiCAD, but on the other hand, FreeCAD being used in a much bigger scope than these applications, the Arch Workbench greatly benefits from the other disciplines FreeCAD caters to, and offers some features rarely seen in traditional BIM applications. The purpose of the Arch Workbench is to offer a complete BIM workflow inside FreeCAD. Also check our tutorials section, and on youtube you will also find a lot more of FreeCAD tutorials. The Getting started page is a must read, if you have no previous experience with FreeCAD. In any case, you should be prepared to look for yourself for further information about how FreeCAD works on the FreeCAD documentation wiki. I will try to make it simple enough so you don't need any previous experience with FreeCAD, but having some experience with 3D or BIM applications will be useful. I have to zoom in to make sure I'm using the right end points.This tutorial aims at giving you the basics to work with the Arch Workbench. Trimming tries to modify the entities to be only within one side of the limiting border, but tangential lines doesn't cut entities into halves.Ģ, move the subsequent entities by moving it's startpoint to the end point of the previous moved entities, by snap to end points only. Since your connections are mostly tangential, a very tricky case for "trimming". It's not trivial for most users to notice this gype of gaps, without enabling the debugging code for hatching. one of the intersections between the two construction circles is the rotation center. you may draw construction circles centered at each end point of this partial, with a radius of the distance between those two end points. I have to zoom in to make sure I'm using the right end points.ģ, continue until I moved away exact one sixth of the contour Ĥ, given a partial contour of one sixth of the whole contour, still need to define a rotation center from which the one sixth of contour spans 60 degrees. I explode the polylines, and move entities away:ġ, move first entity away by some offset Ģ, move the subsequent entities by moving its startpoint to the end point of the previous moved entities, by snap to end points only. ![]() I didn't spend time to check whether these gaps are from polyline creation (if so, it's a bug of polyline). Trimming tries to modify the entities to be only within one side of the limiting border, but a tangential line doesn't cut entities into halves. Please test the contour on the right side (on layer 2) I took some time to modify your drawing to create a continuous contour, and hatching works after that. Some troubleshooting shows it's a contour connection issue instead of a bug of LibreCAD.īasically, there are many gaps at 0.001 or 0.0001 level in your contour. ![]()
