I am working on a model with rigid bodies and encountered this error as I was developing an early demo version using simplified geometry. My intent was to create a rigid body with MASS21 and TARGE170 elements. The TARGE170 elements were intended to form the outline of the rigid body mainly for visual purposes but could also be used for applying load conditions (in addition to a TARGE170 element for the pilot node). I am open to other suggestions but I have gotten something similar to work with straight lines and splines. It was also unexpected that LMESH can only produce a single TARGE169 element with TSHAP,ARC and could not automatically discretize the arc into smaller pieces using LINE or PARA shaped TARGE170 elements.&lt;\/p&gt;&lt;p&gt;Below is a minimum working example which reproduces the issue. Here though I am creating a line using LARC instead of importing from Parasolid. The example can be run without an error message if the element is changed to TARGE169 but then the element is projected to the X-Y plane.&lt;\/p&gt;<\/p>\n<pre>&lt;span style=\"font-size: 10pt;\"&gt;FINISH&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;\/CLEAR&lt;\/span&gt;&lt;br&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;\/PREP7&lt;\/span&gt;&lt;br&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;K,1,-0.5,0.5,0.1&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;K,2,0.5,0.5,0.1&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;K,3,0,0,0&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;LARC,1,2,3,1&lt;\/span&gt;&lt;br&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;ET,1,TARGE170&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;ALLSEL&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;LATT,,,1&lt;\/span&gt;&lt;br&gt;&lt;span style=\"font-size: 10pt;\"&gt;LMESH,ALL&lt;\/span&gt;<\/pre>\n","protected":false},"template":"","class_list":["post-251118","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi Rahul,Thank you for your response.
