RsMesh2Surfs :

Question: Why after I clicked Check button, the program said “ Curve network has bad connectivity ”, and it failed to create faces?

Answer: After Check button was clicked, the program will check the connectivity of the curve network. If there is a curve which has one independent end point, the program will fail to create faces and give the prompt “Curve network has bad connectivity”.

Question: How to avoid bad curve network connectivity?

Answer: We recommend you view our training video file http://www.resurf.cn/maindoc/curve_network.rar (3.8MB), this video file will teach you how to create the curve network with good connectivity. To avoid bad connectivity, you need to pay more attention on capturing the end point of the old line when you are starting to create a new line on the mesh. When you move the mouse cursor along a line, there will be a prompt said 'End' or 'Mid' under the cursor(see the attached picture). 'End' means your mouse cursor will snap the end point of the line; 'Mid' means you will snap the interior point of the line. In order to create good connectivity, you need to use 'End' to snap the end line point to make a network knot. Do not use 'Mid' to snap the end point (this is often the reason of bad connectivity). And usually, in order to make sure end snap, you need to zoom in your model. In this way, the bad connectivity is avoided. In order to snap the end point, please keep the Rhino snap functionality open (see the checkbox on the bottom of Rhino window).

Question: Does RhinoResurf support ‘T-junction' in the curve network?

Answer: No. The current RhinoResurf does not support ‘T-junction' in the curve network. We may support it in the future.

Question: What is ‘T-junction' knot in the curve network?

Answer: When an end point of a curve snaps an interior point of another curve, this results in ‘T-junction' in the curve network. Please see the following picture.

Question: Why RsMesh2Surf fail to create surface?

Answer: If RsMesh2Surf can not create surface, it might be 2 cases:
case 1: your model may be closed. Closed model is not supported in the current version;
case 2: your model may not be clean topology. Clean mesh means any two triangle share only one edge; any edge is shared by one triangle (boundary line) or two triangles. This clean mesh gives us good topology connectivity information and helps us to create surface automatically. If the topology is bad, it is very hard to get the correct topology information for automatic running. Therefore, for such bad topology mesh, we recommend user export the model into point type file firstly, then use RsPoints2Surf to convert, RsPoints2Surf means only the point information used for conversion.
