[View] or [File - Import] Duplicate node/element view / CAD DXF Import Visual Error Troubleshooting

Question: 

I’ve been encountering an issue where MIDAS will show duplicate nodes located near to one another when in reality there is only one node. I am undertaking some detailed modeling, and this issue is making the modeling difficult. 


Answer:

This is a common error occurred in a model that was generated by importing a CAD model. MIDAS has a CAD engine but it is optimized for the range of 500,000 coordinate magnitude or lower. For example, midas Civil can handle up to 500,000 without much issue but if the coordinate magnitude becomes greater than 500,000, then the display error starts occurring. Thsi is regardless of the unit system being used. The same rule applies to 500,000 ft or 500,000 m. 


This display issue does not affect the analysis or design result; however, for the modeling, we recommend to keep midas Civil model close to the origin coordinate. The model can be moved to close to the origin point in CAD file or in midas Civil file. In midas Civil, [Node/Element] > [Translate] > [Move] option can be used.
