AutoCAD - 3D objects Grip

jbbWV9LH — Tue, 13 Sep 2022 13:44:08 GMT

This problem just occurred without me making any system changes.

Basic issue - 2D rectangle has grips that allow me to stretch (this is good). When I extrude into a 3D object, the grips remain (problem). Never used to happen. Not sure what settings changed and I can't find solution anywhere. I only want the corner grips for moving the 3D object.

screenshot-1 shows 2D and the 3D version of it. I cirlced the grips that just started appearing.

screenshot-2 - shows 3D of how the object is supposed to appear.

3D Object Snap On - turned off

Object Snap On - turned on

Only command that has worked but requires input for each 3D object is BREP. Never had to input this before.

You can use PRESSPULL for an enclosed area.
or
Try making a REGION inside there. That will EXTRUDE into a 3D Solid.

Those options don't quite work for me and I am more concerned of fixing a setting issue rather then other ways to make my object.. I have in-house software that works perfectly with how I have made these objects for years.

Standard method I use:

rectangle - create dimensioned rectangle polyline

extrude - set depth of box

This method randomly started to create a 3D object that can be stretched (never used to). I need that setting to be fixed but I am not sure how or what the setting may be that changed.

SUBOBJSELECTIONMODE and/or GRIPSUBOBJMODE System Variables, perhaps? [I didn't explore them thoroughly, but they look related to the question.]

When you edit the solid not using the grips it changes the solid type. When the solid is a box (or any of the primitive solids as well as extrusions), the grips appear. If you do something outside of grip editing like presspull the solid type goes away and it changes to just a solid.

you can use the BREP command to remove the 'history' of a primitive. It will leave you with fewer grips.

Might be good time to share old/new DWG files that show the difference, plus screenshots that are not 2D views.

Jbb.....CADnoob is on the right path. there are a number of ways, like you said, to generate a solid from a rectangle. i feel it may rest in the SOLIDHIST & SHOWHIST settings that seemingly jumped its status. SOLIDHIST tells acad to keep the rectangle and any other primitives that you used to create the solid. although invisible, unless the other settiing SHOWHIST is set to on or 2, etc. the BREP command that CADnoob speaks of deletes the history of the shapes you select to be " BREPPED". AND even though you may BREP all or some of the graphics, if these settings are not changed, from the BREP point forward you will again be saving the history of shapes used to build your solid. if you are provided grips on a solid, there is some history behind the scenes that acad is hanging on to. if you wish to start where you are, clean of history shapes, execute the BREP command and select all the graphics. i would do it twice. before exectuing the BREP command, you may want to s4et the showhist system variable to 1 so you would have a better understanding of where these fugitive shapes are seated at. but at the end of the day, what i hear you wanting to do is

1. set system variable SOLIDHIST to 0.

2. set system variable SHOWHIST to 1.

3. perform BREP.

4. set system variable SHOWHIST to 0.

setting the SHOWHIST back to 0 is sort of a mute point after setting the SOLIDHIST to 0. Because the file will no longer save any of the shapes you use to create your solid. so if you SOLIDHIST 0......then it irrelevant what the setting of SHOWHIST is set at, for there will be no history to speak of, after the fact.

extrude on!!!

I looked into all these suggestions - nothing worked.

Based on everything I read, the history of the geometry to the 3D solid is remaining even though SOLIDHIST and SHOWHIST are set to 0.

My next attempts to fix were:

Tried resetting settings to default - didn't change anything.

Imported colleagues autocad settings - didn't change anything.

Two pictures below:

1 - extruded - shows the grips at the midpoints I can't remove still

2 - BREP - how I would like my 3D solids to appear without requiring the solid to be "BREPPED"

With the creation of solid primitives, there grips are created by default (at least from everything I'm seeing). If something has changed, from the way it used to work, then it used to be broken and now is functioning as intended as far as i can tell. Have you had any third party apps or lisps that you used to use that are no longer there?

If you don't like BREP you can use SOLIDEDIT and then clean. It will make it a non primitive solid as well i believe.

Perhaps change the cui or make a macro to convert it after the solid is created.
