Hi, I have been working on Lead Screw Bolt side and while importing the file in STEP format from SolidWorks. it shows me a info of about having NURBS in my geometry which is logical as i have been using Helix command for making threads on bolt. But issue is, it is taking really hard time to make simple mesh like hours and hours. I already had issues while importing the Geometry in IGES format which convert my solid part into surface. Suggest me How to Deal with NURBS to make good mesh in short time

The ANSYS Project File is attached

Just Lead.wbpz

You did not get a good translation from SolidWorks.
Try exporting a Parasolid and import that into DesignModeler.

I tried to export parasolid format file into design modular but Still getting NURBS and a bad spline ( Shown in attached picture). This spline is not Prominent in DM but in mesh condition it comes out. More, the Space claim is not opening this format file.

Please rename the Parasolid file and use a .txt file extension so you can attach it to your reply. SolidWorks may not have created clean geometry.
Did you try the Repair tool in DM?

This is the File of lead Screw. and as you asked to tell you about using the repair tool. yes, I tried them to remove champers and small edges and merged faces but all in Vain. Luckily, after hours and hours the simple STEP AP214 format gave me a Meshed part without doing any fancy edge removals and face merges. I just want to know why this happened and for the next time, what should we do if anyone stuck at that point.

Here is the error in DM. The Repair tool in DM cannot repair this.
I expect you can tighten the tolerance in SolidWorks before you export the geometry.

Most of your problems are caused by the four tiny blends on these edges. If you didn't have those, everything would be much easier and faster. In SolidWorks, delete these four blends and export that solid.
