If you need a permanent construction layer (or layers) simply create them and turn visibility on and off. Add other entities as required including additional straight lines which will also become temporary construction lines. Draw your straight line (horizontal, vertical or at an arbitrary angle), make it as long as it needs to be as a part of the drawing then switch on construction layer. This gives almost the best of both worlds which I think is what you were actually hoping to achieve. My previous experience in CAD was with the old Draft Choice program, so Im presuming I have some holdover misconceptions. You can then create a new entity remote from but in line with that existing straight line then turn off the construction layer. Greetings, Im (obviously) new to LibreCad, so I have some basic misunderstandings in drawing simple objects with which I need help. What I find fascinating about LibreCAD is that any existing straight line (excluding those that are either polylines or part of a rectangle) can be turned (temporarily) into a construction line by toggling on construction layer. The remaining information about LibreCAD is scattered around various web pages, user discussions, and on YouTube. While I have not used AutoCAD for about 30 years the official literature seems to make this fairly clear. LibreCAD does not have a decent user’s manual and the brief tutorials that exist are partly obsolete geeks do not like to write manuals. Either way both regard such lines as temporary guides to assist in placing other entities. ![]() Start with liberal card with a complete project to create a floor plane, floor plane for house. Construction Lines in LibreCAD are almost the same as those in AutoCAD About Contruction Lines The main difference seems to be that AutoCAD allows for construction circles based on arcs (something that can be replicated in LibreCAD with a normal circle suitably attributed). Its Nicholas and welcome to this course on Libor credit.
